RESUMO

We report the first preparation of a monoclonal antibody (mAb) that can immobilize a palladium (Pd)-complex. The allylic amination reaction using a supramolecular catalyst consisting of the Pd-complex and mAb selectively gives the (R)-enantiomer product with an enantiomeric excess (ee) of 98 ± 2%. This is in sharp contrast to the reaction catalyzed by a conventional Pd-catalyst (ee < 2%).

RESUMO

The effects of foliar Se biofortification (Se+) of the lettuce on the transfer and toxicity of Hg from soil contaminated with HgCl2 (H) and soil collected near the former Hg smelter in Idrija (I), to terrestrial food chain are explored, with Spanish slug as a primary consumer. Foliar application of Se significantly increased Se content in the lettuce, with no detected toxic effects. Mercury exerted toxic effects on plants, decreasing plant biomass, photochemical efficiency of the photosystem II (Fv/Fm) and the total chlorophyll content. Selenium biofortification (Se+ test group) had no effect on Hg bioaccumulation in plants. In slugs, different responses were observed in H and I groups; the I/Se+ subgroup was the most strongly affected by Hg toxicity, exhibiting lower biomass, feeding and growth rate and a higher hepatopancreas/ muscle Hg translocation, pointing to a higher Hg mobility in comparison to H group. Selenium increased Hg bioavailability for slugs, but with opposite physiological responses: alleviating stress in H/Se+ and inducing it in I/Se+ group, indicating different mechanisms of Hg-Se interactions in the food chain under HgCl2 and Idrija soil exposures that can be mainly attributed to different Hg speciation and ligand environment in the soil.

RESUMO

BACKGROUND: We analyse the distribution of Gastropods and Chitons from shallow to deep waters along the southwestern Atlantic Ocean off Argentina and discuss possible factors determining the observed biogeographic patterns. RESULTS: Three major biogeographic groups are defined on the basis of Gastropod and Chiton species associations, i.e., continental shelf (< 350 m), upper continental slope (> 350-2000 m) and lower continental slope (2000-3000 m). Bathymetry appears as the main factor modifying large-scale distribution of the fauna at a. In this scenario, species associations are determined by marine currents that clearly occur at a particular and well defined depth. No arrangement of species by geographic location was found in assemblages from the continental shelf and upper continental slope. CONCLUSIONS: We hypothesize that depth and marine currents are the main factor affecting the distribution of Gastropods and Chitons along the SW Atlantic between 200 and 3000 m depth.

RESUMO

The deep-water mollusks collected during the Marion Dufresne (MD55) expedition to the southeastern Brazilian coast in 1987 have been studied in several recent works. The present paper lists and diagnoses 19 species belonging to the vetigastropod families Calliostomatidae, Colloniidae, Margaritidae, and Solariellidae. A new species, Calliostoma valkuri sp. nov., is described. It is mainly characterized by a very short teleoconch I, with limits marked by conspicuous varices and sculpture consisting of 3 spiral threads; sculpture of the teleoconch II consisting of spiral cords with thorn-like projections; and the presence of two strongly marked cords on the median portion of the whorls. Based on the MD55 samples and complementary specimens from other expeditions, the following species have their geographical and/or bathymetrical range extended: Bathymophila euspira, Calliostoma gemmosum, Calliostoma rude, Callogaza watsoni, Gaza compta, Falsimargarita terespira, Homalopoma boffii, Lamellitrochus cancapae comb. nov., Lamellitrochus pourtalesi, Margarites imperialis, and Solariella quinni.

RESUMO

Ongoing surveys for skinks of the genus Lerista in north Queensland have resulted in the collection of voucher specimens from two populations formerly assigned to Lerista storri Greer, McDonald Lawrie, 1983 that are geographically isolated from the type population and show a degree of morphological variation differing from the type population. Analysis of recently collected material has confirmed both populations are specifically distinct to the type population, with one being more closely related to Lerista ameles Greer, 1979, another little known, north Queensland species. Consequently, these populations are described as Lerista alia sp. nov. and Lerista parameles sp. nov. The morphological diversity of L. storri is thereby restricted, necessitating a redescription. The conservation status of all these taxa is discussed.

RESUMO

The complete larval and first crab stages of the decorator crab Camposcia retusa (Latreille, 1829) are described and illustrated based on laboratory-reared material for the first time. Specimens were obtained from larvae hatched from adult crabs collected from coral reefs of Queensland, Australia. Newly hatched larvae were successfully reared to settlement as the first-stage crabs. Larval development consisted of two zoeal stages and one megalopal stage. The morphology of each larval stage was compared with those available from a previous study using material from the Red Sea. Due to substantial differences in morphology of the second zoeal and megalopal stages between the two studies, we argue that these larval stages described by the earlier report may not be that of C. retusa. Finally, the morphological characters of both larval and first crab stages of C. retusa are also compared with the corresponding stages of previously reported Inachidae.

RESUMO

Leptobrachella (Anura: Megophryidae) is currently composed of seventy-one species distributed in China and Southeast Asia (Frost 2018). Fourteen species of Leptobrachella are currently known from southern China: L. alpina (Fei, Ye Li, 1990), L. laui (Sung, Yang Wang, 2014), L. liui (Fei Ye, 1990), L. mangshanensis (Hou, Zhang, Hu, Li, Shi, Chen, Mo Wang, 2018), L. maoershanensis (Yuan, Sun, Chen, Rowley Che, 2017), L. oshanensis (Liu, 1950), L. purpura (Yang, Zeng Wang, 2018), L. tengchongensis (Yang, Wang, Chen Rao, 2016), L. wuhuangmontis (Wang, Yang Wang, 2018), L. yingjiangensis (Yang, Zeng Wang, 2018), L. yunkaiensis (Wang, Li, Lyu Wang, 2018), L. ventripunctata (Fei, Ye Li, 1990), L. pelodytoides (Boulenger, 1893) and L. sungi (Lathrop, Murphy, Orlov Ho, 1998) and the first eleven species are endemic of this region (AmphibiaChina 2018). Many new species in this genus were discovered based on molecular, morphometric and bioacoustic data in recent years (Frost 2018). In comparison to molecular and morphological data, bioacoustics is especially useful in species identification of Leptobrachella in field surveys (Rowley et al. 2016). Although the advertisement calls of many Leptobrachella species were described along with the species descriptions (e.g., Rowley et al. 2016), the advertisement calls of only three Chinese endemic species (L. alpinus; L. laui and L. oshanensis) are known (Jiang et al. 2002; Matsui 2006; Xu et al. 2005). Here, we describe the advertisement calls of L. liui, which inhabits rocky streams in southeastern China (Fujian, Jiangxi and Zhejinag) and is morphologically diagnosed by the combination of a set of external color traits (Fig. 1).

RESUMO

Gothograptid retiolitines were distinctive in being one of the very few graptolite groups to thrive through the late Wenlock extinction event that killed off most graptoloid species, and their distinctive construction may have been a factor in this success amid environmental adversity. New and rich material from two localities in Poland and five localities in Lithuania contains Gothograptus nassa, Gothograptus obtectus and four new species. The detailed morphology and reconstruction of the tubarium shows its specific features, different from other lundgreni Biozone retiolitines. The tubarium is narrow, elongated, finite, massive and compact. The thecal orifices are hidden by simple hoods or by extraordinary reticulated veils, which may cover the ventral walls. The colonies of Gothograptus species from the lundgreni Biozone are short, usually having eight pairs of thecae, whereas species from the post-lundgreni interval may reach more than 20 pairs of thecae. A common feature of Gothograptus species is the presence of singular genicular structures tightly covering thecal orifices. Reticulated hoods and veils are characteristic of species from the lundgreni Biozone. The most common such structures are nassa hoods, located on the proximal thecae in some species from the lundgreni Biozone, and on every theca of post-lundgreni species. Only Gothograptus domeyki n. sp. has no genicular processes on most thecae. Within a total of four species from the lundgreni Biozone and three species from the nassa and praedeubeli Biozones, we describe here the new species Gothograptus domeyki and Gothograptus velo from the lundgreni Biozone, Gothograptus diminutus from the parvus/nassa Biozone, and Gothograptus auriculatus from the dubius/nassa and praedeubeli biozones; G. auriculatus n. sp. is the youngest form of the genus Gothograptus. Variation within the genus Gothograptus during the post-lundgreni interval period is shown for the first time.

RESUMO

An unfamiliar gastropod was collected from a deep-sea whale carcass at the base of the São Paulo Ridge in the Southwest Atlantic by the manned research submersible Shinkai 6500, and is here described as a new species of the abyssochrysoidean genus Rubyspira, R. brasiliensis sp. nov., following morphological and molecular phylogenetic examinations. There are only two other known species in the genus, which occur together in the Monterey Submarine Canyon off California. The present new species was shown by the molecular analysis to be closer to one of the Californian species than the other. It was found aggregated on and around a whale carcass at a depth of 4204 m, which represents the deepest record of whale- fall ecosystems ever discovered.

RESUMO

Fasciolariids are buccinoid neogastropods and key predators in the tropics and subtropics, comprising more than 500 species in the subfamilies Fasciolariinae, Fusininae and Peristerniinae. Tulip shells, horse-conchs, spindles, etc., have been grouped into heterogeneous combinations of unrelated species, while several generic names have been used to group conchologically similar species. The latest molecular phylogenetic study conflicts with the current circumscription of many genera, and even more so, with the three currently recognized subfamilies. This work is the first morphological approach to the phylogeny of fasciolariids, using a parsimony analysis in TnT of 53 taxa based on 100 characters. This analysis reveals a monophyletic Fasciolariidae, with the genera Dolicholatirus and Teralatirus representing the most basal clade in the family, followed by three nodes that correspond to a fusinine grade, which includes the genus Pseudolatirus (Peristerniinae). A terminal clade groups the peristerniine genera Peristernia and Fusolatirus, fasciolariines and the remaining peristerniines. Although none of these clades correspond to currently accepted taxonomic groups, the latter two clades are corroborated in the most recent multilocus molecular phylogeny. This study supports the utility of morphological data in the recovery of groups, even in the molecular era.

RESUMO

We present a critical evaluation of the taxonomy, stratigraphy and biogeography of the turritellid gastropods of the Miocene Paratethys Sea. 159 species-level names and 6 infrasubspecific names have been used for Paratethyan Turritellidae since 1848. Of these, only 35 species are accepted herein as valid species, with some uncertainties due to poor preservation or limited access to type material. Maximum diversities occurred during the early middle Miocene (Langhian, Badenian) coinciding with the Miocene Climatic Optimum. Whilst early Miocene turritellid assemblages are characterized by large to very large species of Peyrotia, Turritella and Allmonia, middle Miocene assemblages are predominated by medium-sized species of Archimediella, Helminthia, Oligodia and Ptychidia. The taxonomic composition of these faunas, with representatives of Archimediella, Helminthia, Mesalia and Vermicularia suggests a biogeographic affiliation with Atlantic and especially West African faunas.                Turritellinella new gen. is established as new genus for the eastern Atlantic-Mediterranean Turritella tricarinata/communis complex. Viennella is described as new genus with Turritella incisaeformis Csepreghy-Meznerics 1956 as type species. Allmonia new gen. is introduced as new genus for European Cenozoic Protominae previously placed in Protoma. For the first time, inner lirae are documented as conchological features of Turritellidae.                Six species are described as new, three within the Turritellinae: Archimediella carpathica new sp., Ptychidia erynella new sp. and Viennella ignorata new sp., and three within the Pareorinae: Mesalia sovisi new sp., Mesalia stryriaca new sp. and Mesalia bohnhavasae new sp.. Ptychidia austrorotundata new nom. is proposed as new name Turritella turris rotundata Schaffer 1912, non Turritella rotundata Grzybowski 1899. We designate lectotypes for Turritella gradata Menke in Hörnes, 1855, Haustator striatellatus Sacco, 1895, Allmonia carniolica (Stache, 1858) and Allmonia alterniplicata (Sacco, 1895). Neotypes are designated for Archimediella abundans (Handmann, 1882), Archimediella hoernesi (Rolle, 1856), Ptychidia partschi (Rolle, 1856), Ptychidia? ernesti (Handmann, 1882). Rhabdosis Townes, 1970 (Hymenoptera, Ichneumonidae) is a junior homonym of Rhabdosis Handmann 1882 (Gastropoda, Turritellidae) and will need a new name.

RESUMO

This paper provides a current overview of the diversity of the marine water mite family Pontarachnidae of the Mediterranean Sea. The checklist includes ten species from two genera, i.e. Litarachna Walter, 1925 and Pontarachna Philippi, 1840. Two species i.e., Litarachna muratsezgini sp. nov. and Pontarachna turcica sp. nov. from the Gulf of Antalya (Levantine Sea, Turkey), are described as new for science. Moreover, the key for the identification of Mediterranean Pontarachnidae species and a brief discussion on the current gaps and future prospects of our knowledge of this important but neglected component of the marine meiofauna are given.

RESUMO

The fasciolariid fauna from two expeditions to French Guiana is examined and augmented with published records and material of other collections from the Guianas and northeastern Brazil. Twelve species of Fasciolaria and Aurantilaria (Fasciolariinae), Aristofusus, Lyonsifusus and Fusinus s.l. (Fusininae), and Lamellilatirus and Polygona (Peristerniinae) are reported and discussed. Nine species are represented in expedition collections, and reports of three other species are evaluated. Two morphologically distinct species of Lamellilatirus are described as new; type localities of both are off French Guiana, 114-118 m. Ten Guianan fasciolariids range variously northward to Caribbean South America and the Lesser Antilles and southward to Ceará, Brazil; one other extends into the northern Caribbean, and one extends southward to Rio de Janeiro, Brazil.

RESUMO

Species from artesian springs associated with the Queensland Great Artesian Basin that were previously included in the tateid genus Jardinella are included in three new genera, namely Eulodrobia, with six species, five of them new and all from the Eulo Supergroup; Springvalia, with one species from the Springvale Supergroup; and Carnarvoncochlea with two previously-described species, from the Carnarvon Supergroup. The genus Edgbastonia is extended to include eight previously described species, in addition to the type species, and four new species-group taxa from the Barcaldine Supergroup springs; all but the type species are included in the new subgenus Barcaldinia. Three new species from non-artesian springs in north Queensland are included in Edgbastonia, one of them tentatively. Two additional related new genera, both with a single new species, are described from outside the Great Artesian Basin; Conondalia from southeast Queensland and Nundalia from north-eastern New South Wales. The genus Jardinella, previously used for all the Queensland spring tateids, is here restricted to three species found in coastal rivers and streams in northeast Queensland. A molecular phylogenetic analysis using COI and 16S mitochondrial genes in combination suggests that the Queensland Great Artesian Basin taxa may be more closely related to the tateid genera Austropyrgus, Pseudotricula, Posticobia and Potamopyrgus than to the South Australian GAB taxa, thus indicating the separate origins of these two desert spring faunas.

RESUMO

Nearly all of the recognized species of sea slugs in clade Sacoglossa (about 300 taxa) are herbivorous, using a uniseriate radula in suctorial feeding. The only exceptions are a pair of monotypic genera in the ceratiform family Limapontiidae: Olea Agersborg, 1923 from the northeastern Pacific, and Calliopaea d'Orbigny, 1837 from the northeastern Atlantic coast of Europe and the Mediterranean. Both genera feed on the eggs of other heterobranchs, notably cephalaspideans, and lack cerata on the anterior dorsum. Major differences are that C. bellula d'Orbigny, 1837 has more cerata than O. hansineensis Agersborg, 1923, a more typical radula with ascending and descending rows of fully-formed teeth, and a much longer penial stylet. Here, we describe a new egg-eating sacoglossan species from the subtropical Gulf of Mexico coast of Florida, U.S.A. Phylogenetic relationships inferred from analyses of a four-gene dataset including 219 sacoglossan species indicated the new taxon (O. hensoni n. sp.) belongs to Olea. The generic placement of the new species is also supported by its highly reduced radula and comparatively short penial stylet. A full description of the reproductive, digestive, and nervous systems is also provided. Finding a new Olea species in the warm waters of the western Atlantic was surprising, given the genus was previously known only from the cold northern Pacific, and suggests further diversity in oophagous sacoglossans may await discovery.

RESUMO

The triphorid genera Inella and Strobiligera are historically considered to represent one or two distinct groups, with recent studies claiming that Strobiligera comprises species with paucispiral or multispiral protoconchs, whereas only species with paucispiral protoconch occur in Inella. The present study aims to update the taxonomy of Inella and Strobiligera (with paucispiral protoconchs) from Brazil. Three main groups are recognized: Inella s.s. and Strobiligera show a simultaneous emergence of the three spiral cords of the teleoconch, the former possessing a discrete nucleus and the latter bearing a distinct globose protoconch; the "pseudo Inella" group has a late emergence of the median spiral cord of teleoconch. Four species were previously recorded from Brazil: I. unicornium, I. longissima, S. pompona and S. compsa, of which the three latter records are disregarded for being based on shells with broken apices and consequent uncertainty of identification. Twenty species in fact occur in Brazil: Inella s.s. is represented by I. apexbilirata and one possible new species; "pseudo Inella" includes "Inella" differens, "Inella" faberi, "Inella" galo sp. nov., "Inella" euconfio sp. nov., "Inella" leucocephala sp. nov., "Inella" faceta sp. nov., "Inella" maculata sp. nov., "Inella" vanilla sp. nov., and three possible new species; Strobiligera is represented by S. unicornium comb. nov., S. gaesona, S. dinea, Strobiligera campista sp. nov., Strobiligera santista sp. nov., and two possible new species. The "pseudo Inella" group is probably derived from unrelated lineages that converged to a simple type of paucispiral protoconch, requiring the examination of radular morphology to properly reallocate those species. The supposed restricted geographical range of triphorids with lecithotrophic development requires future investigations of the five species from the northwestern Atlantic/Caribbean that are herein recorded to Brazil. Key words: Triphoroidea, marine molluscs, lecithotrophic development, western Atlantic  Introduction Triphoridae is a speciose family of marine snails that feed on sponges, with 642 Recent valid species (WoRMS 2018) and hundreds of undescribed species (Albano et al. 2011). The genus Inella Bayle, 1879 is one of the most challenging taxa in Triphoridae, especially because of its uncertain taxonomic limits and high number of described species (Marshall 1983). Inella and Strobiligera Dall, 1924 are historically considered to represent one or two distinct groups, with recent studies claiming that Strobiligera comprises species with paucispiral or multispiral protoconchs, whereas only species with paucispiral protoconchs occur in Inella (Fernandes Pimenta 2014). A brief taxonomic overview of this issue will be addressed in the next lines.Hinds (1843) proposed the name Ino (preoccupied by the crustacean genus Ino Schrank, 1803; Inella Bayle is a replacement name) for cylindrical, elongated and acuminated triphorid shells. Jousseaume (1884) added that the shell of Inella is composed of at least 15 whorls, sculptured by spiral tubercles, with the last whorl presenting a depressed base and two apertures (i.e., the true aperture and the anterior canal). Laseron (1958) recognized that the Inella concept of Hinds (1843) mixed different shell types; however, Laseron broadened the definitions of Inella, as he also stated, warning that the use of protoconchs could need further generic revision. Kosuge (1966) defined Inella as having axial sculpture and three spiral cords on the teleoconch, a blunt and dome-shaped protoconch with a few spiral ridges, and suggested that Inella belongs to the most advanced group of triphorids. Marshall (1983) proposed the distinction between the "Triphora group" and the "Inella group" (composed of Inella Bayle and related genera) in Triphorinae, perhaps worthy of subfamily distinction, although this division is still informal (Marquet 1996). Marshall (1983: 19) also applied the term Inella s.l., recognizing that it contains "a number of natural groups that are worthy of genus-group status, most of which are as yet unnamed". Simone (2006) interpreted Inella as triphorids with a very elongated shell, a relatively straight spire profile and a projected aperture. Rolán Fernández-Garcés (2008) followed the concept of the catch-all taxon Inella s.l., uniting several species with very different shell forms under a more or less classical protoconch of Inella (i.e., without axial sculpture). Fernandes Pimenta (2014) recognized that lecithotrophic species of Strobiligera have a very inflated protoconch (following Dall 1924), which is distinct from the reduced nucleus observed in Inella s.l., thus substantially reducing the number of species from the Atlantic Ocean previously allocated to the latter.            Marshall (1983) did not indicate any junior synonym for Inella, but Rolán Fernández-Garcés (2008) placed the type species of Strobiligera within Inella, which was later rejected by Fernandes Pimenta (2014). Marquet (1996: 141) mentioned that "Marshall (1983) placed Norephora in synonymy with Inella"; this is not true, as Marshall (1983: 81) only indicated that "Norephora is probably closely related to Inella Bayle" when compared with Talophora Gründel, 1975. In fact, Fernandes Pimenta (2014) suggested that Norephora is probably a synonym of Subulophora Laseron, 1958, pending further investigation. Wenz (1938 apud Kosuge 1966) suggested that Tristoma Menke, 1830 and Biforina Bucquoy, Dautzenberg Dollfus, 1884 were synonyms of Inella, but Marshall (1983) stated that the first is a synonym of Triphora Blainville, 1828 and the second is a synonym of Monophorus Grillo, 1877.Although many species remain to be described in these genera, Inella and Strobiligera are represented altogether by 64 Recent species worldwide (Bouchet Rosenberg 2013; Bouchet Gofas 2014). Both genera are particularly common in mid-low depths of the continental shelf and in the continental slope, especially Strobiligera (Fernandes Pimenta 2017a). Species with paucispiral protoconchs in both groups are absent from the eastern Atlantic (e.g., Bouchet 1985; Rolán 2005), although well-represented in the western Atlantic, with 27 Recent species (Simone 2006; Rolán Fernández-Garcés 2008), mainly in the Caribbean and adjacent regions. Only four of these species were reported from Brazil: Inella unicornium Simone, 2006 is the only endemic species of this genus in Brazil; Strobiligera compsa (Dall, 1927) and Strobiligera pompona (Dall, 1927) were respectively considered misidentifications of Absalão (1989) and Rios (1975, 1985, 1994, 2009) by Fernandes Pimenta (2014); and Inella longissima (Dall, 1881), reported by Rios (1985, 2009) from southern Brazil, replacing his prior identification of Inella triserialis Dall, 1881 (Rios 1975).The main objective of the present work is to update the taxonomy of Inella and Strobiligera species with paucispiral protoconchs, given that Strobiligera species from Brazil with multispiral protoconchs were already reviewed by Fernandes Pimenta (2014), filling a large gap in taxonomic knowledge.

RESUMO

Three species in the gastropod genus Calliostoma are confirmed as living in Deep-Water Coral (DWC) habitats in the NE Atlantic Ocean: Calliostoma bullatum (Philippi, 1844), C. maurolici (Seguenza, 1876) and C. leptophyma Dautzenberg Fischer, 1896. Up to now, C. bullatum was only known as fossil from Early to Mid-Pleistocene outcrops in DWC-related habitats in southern Italy; our study confirmed its living presence in DWC off Mauritania. A discussion is provided on the distribution of DWC-related calliostomatids in the NE Atlantic and the Mediterranean Sea from the Pleistocene to the present.

RESUMO

This paper provides the first phylogenetic classification of the Atlides Section (Lycaenidae: Theclinae, Eumaeini).  It is based on a recently published morphological phylogenetic study, in which the Atlides Section proved to be monophyletic in all analyses. In particular, that study identified a hindwing cleft anal lobe in all members of the Atlides Section that is lacking in all other Eumaeini (except for some species of Panthiades Hübner). The included genera are Theritas Hübner; Arcas Swainson; Lucilda d'Abrera Bálint; Pseudolycaena Wallengren; Brangas Hübner; Atlides Hübner; and Denivia K. Johnson. Each is characterized by synapomorphies. Margaritheclus Bálint and Dabreras Bálint are new generic synonyms of Lucilda and Brangas, respectively. We recognize 71 species. Distribution and habitat are provided for each, and nomenclature is updated. Atlides centralis Salazar Henao is a new synonym of Atlides browni Constantino, Salazar K. Johnson; Brangas contrastus Bálint is a new synonym of Brangas felderi (Goodson); Denivia grava Bálint, K. Johnson Kroenlein is a new synonym of Denivia deniva (Hewitson); Denivia ponsanota Bálint, K. Johnson Kroenlein is a new synonym of Atlides zava (Hewitson); Denivia striata Bálint, K. Johnson Kroenlein is a new synonym of Atlides zava (Hewitson); Margaritheclus boliboyeri Bálint Wojtusiak is a new synonym of Margaritheclus boliboyerus Bálint Wojtusiak; and Theritas gozmanyi Bálint Wojtusiak is a new synonym of Theritas paupera (C. Felder R. Felder). New combinations are Lucilda margaritacea (Draudt), Lucilda danaus (C. Felder R. Felder), Lucilda dabrerus (Bálint), Lucilda boliboyerus (Bálint Wojtusiak), Denivia curitabaensis (K. Johnson), Denivia augustinula (Goodson), Denivia theocritus (Fabricius), Denivia augustula (W.F. Kirby), Denivia arene (Goodson), Denivia monica (Hewitson), Denivia hemon (Cramer), Denivia phegeus (Hewitson), Denivia acontius (Goodson), Denivia chaluma (Schaus), Denivia viresco (H.H. Druce), Denivia silma (Martins, Faynel Robbins), and Denivia lisus (Stoll).
