RESUMO

It is still a challenge to solve the matrix interferences in veterinary drug residue analysis. In this study, we reported a thin layer chromatography (TLC)-high-performance liquid chromatography (HPLC) method for determining total florfenicol (FF) residues, expressed as florfenicol amine (FFA), in porcine edible tissues. The tissue homogenate were acid-hydrolyzed to liberate the bound residues and convert them into FFA. The hydrolysates were washed with ethyl acetate and subsequently extracted with ethyl acetate under alkaline conditions. The supernatants were concentrated through evaporation, defatted with hexane, purified by TLC and analyzed by HPLC at 225 nm. The optimal developing solvent for TLC purification was ethyl acetate-acetone-ammonium hydroxide mixtures (2:8:0.5, v/v/v). The method was fully validated according to decision 2002/657/EC, and could be used for the routine monitoring of FF residues in pig. TLC showed excellent purification efficiency, and was expected to solve the matrix interferences in veterinary drug residue analysis.

RESUMO

Among the currently recognized 71 extant genera of Glandulariini, Afroeudesis Franz shows an unusual distribution, with strikingly similar species known from South America, west and east Africa, and the sub-Himalayan region of Asia. Morphological studies revealed that several species placed in other genera share with Afroeudesis several unique characters, among others a symmetrical pattern of numerous setae on the frons and vertex, not known in any other Glandulariini. This 'Afroeudesis group' is here recognized to be composed of the Neotropical genera Meridaphes Jaloszynski, Stenichnoconnus Franz and Pseudoraphes Franz, the broadly distributed Afroeudesis, and the Neotropical Bicarinulodes gen. n. The last is proposed for a species previously misplaced in Microscydmus Saulcy Croissandeau, resulting in Bicarinulodes meridensis (Franz) comb. n. Bicarinulodes is most similar to Afroeudesis, but (among other differences) it lacks the apomorphy that is unique for the latter genus, the raised subtriangular 'platform' on the frons and vertex. Stenichnoconnus minor (Franz), comb. n is proposed for Euconnus minor (Franz), originally published as Venezolanoconnus minor Franz. Stenichnoconnus and Pseudoraphes are redefined and redescribed.

RESUMO

Penia Laporte, 1838 is the most species-rich genus in the click-beetle tribe Dimini. Penia is distributed in the Himalayas, East and South East Asia. In this paper, we describe P. mantillerii sp. nov. from northern Vietnam. This species is easily recognizable due to its elongate body and large window-like elytral punctures. The most morphologically similar species to P. mantillerii sp. nov. are P. costipennis Fleutiaux, 1936 and P. sucinea Schimmel, 2001, which also occur in northern Vietnam. Male pregenital segments and genitalia are figured for the first time for P. sucinea. An identification key to the Penia species from Vietnam and surroundings is provided.

RESUMO

Despite the ubiquitous nature of symbiosis in palaemonid shrimps (Caridea: Palaemonidae) which live in or on varied invertebrate hosts, such as echinoderms, sponges, ascidians, hard and soft corals, etc., very few taxa have been recorded living in burrows constructed by other animals. This is in sharp contrast to the rich burrow-dwelling diversity in the Alpheidae, in which numerous genera associate with a great variety of burrowing animals, including stomatopods (Hayashi 2002; Duris Anker 2014), echiurans (Anker et al. 2005, 2015), other alpheid shrimps (e.g. De Grave 2004; Anker Marin 2006), and especially numerous ghost and mud shrimps (e.g. Anker, 2011; Anker Lazarus 2015).

RESUMO

Samples of Pectinariidae in the Australian Museum and Museums of Victoria, Australia were examined. Thirteen species were identified, including three additional records of previously recorded species of Amphictene and two new species, A. cercusa n. sp. and A. undulata n. sp., two species of the genus Lagis which has not previously been recorded from Australia, including a new species, L. portus n. sp., and five additional records of previously recorded species of Pectinaria and one new species, P. ningalooensis n. sp. The study revealed additional characters which are useful to identify species of pectinariids, a pair of ear-shaped lobes which are adjacent to both sides of dorsal base of cephalic veil in species of Pectinaria and Amphictene, but in Lagis they are present between the buccal cavity and lateral margin of segment 1; and a pair of ventral lappets which have not previously been described on the lateral margin of segment I in all species of pectinariids from Australia. For species where numerous individuals were available for study, we investigated how some characters, change with increasing body size. A key to all recorded species from Australia is given, but does not imply any phylogenetic relationships.

RESUMO

The genus Platyscelis Latreille, 1818 (Coleoptera: Tenebrionidae: Platyscelidini) from China is revised. Sixteen valid species (subspecies) are recognized in this study, including three new ones: P. (s. str.) acutipenis sp. nov. from Gansu and Ningxia, P. (s. str.) densipunctata sp. nov. from Gansu, and P. (s. str.) helanensis sp. nov. from Inner Mongolia and Ningxia. A synonymy between P. (s. str.) brevis Baudi di Selve, 1876 and P. ballioni Reitter, 1889 is proposed based on the examination of type and additional specimens. Lectotypes are designated for P. hauseri Reitter, 1899, P. gebieni Schuster, 1915, P. (s. str.) angusticollis Kaszab, 1940, P. (s. str.) licenti Kaszab, 1940, P. (s. str.) platytarsis Kaszab, 1940 and P. (s. str.) suiyuana Kaszab, 1940. Furthermore, new distribution records, images of adults and male aedeagus, and a key to Chinese species are presented.

RESUMO

Purcell (1908) and Simon (1910) described or reported 181 spiders from southern Africa based on the material collected by German zoologist and anthropologist Leonhard Schultze in 1903‒1905. The expedition route passed through several countries/territories that have since changed their boundaries and/or names. The two mentioned papers included 32 localities in three modern countries, aside from broader geographical regions (e.g. Hereroland) without specified localities. In this paper, we list all species reported or described, their current taxonomic status, provide the correct data about the countries from where these species were described, and their current distributions based on taxonomic publications. Purcell and Simon treated 81 and 100 species respectively, of which 49 and 67 respectively were new. A sizeable proportion of these species have since been transferred to other genera or proposed as synonyms. In evaluating all of the localities provided in the treatments of species in these two papers, as well as subsequent taxonomic literature, we found that 25 of the 68 nominative species treated by Purcell and 38 of the 92 species treated by Simon had incorrect distribution data in the World Spider Catalog (2019). We provide revised distribution information for all of these, and discuss the importance of correct information in the preparation of national faunistic lists.

RESUMO

We describe a new species of rock gecko of the genus Cnemaspis from Java, Indonesia, representing the first record of the genus for this Island. The new species was collected from the southern slopes of Gunung Muria, a dormant volcano in Central Java. The new species is easily distinguished from all congeners by having a maximum SVL of 58.1 mm in males and 56.9 mm in females; a pair of sharp conical tubercle clusters on the occiput; a warty bridge on the nuchal loop, extending from the upper tympanum and curving to the nape; dorsal tubercles not linearly arranged; 18-20 paravertebral tubercles; postmentals separated by one scale; gular, pectoral and abdominal scales, ventral scales of fore- and hindlimbs, and subcaudal scales keeled; no tubercles on lower flank; precloacal and femoral pores absent; enlarged submetacarpal scales present on the first digit of the manus; 38-40 ventral scales; 31-35 lamellae under fourth toe; two postcloacal tubercles on each side; enlarged median subcaudal scales row present; caudal tubercles encircling tail; and a sexually dimorphic ventral color pattern, with males having a yellow belly and females white and the ventral surface of the tail in males yellow proximally changing to white at mid-length, whereas in females, alternating black and white rings completely encircle the tail, which is black distally.

RESUMO

In this contribution to the study of gryllacridines or raspy crickets (Orthoptera: Gryllacrididae), a new proposal for classification of this family is provided, dividing it into two subfamilies and ten tribes that includes most of the 114 known genera to date (including the new genera described here). It describes and redefines two subfamilies: Hyperbaeninae n. subf. and Gryllacridinae n. sensu, ten tribes: Phryganogryllacridini n. trib., Capnogryllacridini n. trib., Asarcogryllacridini n. trib., Hyperbaenini n. trib., Paragryllacridini n. trib., Ametrini n. trib., Ametroidini n. trib., Gryllacridini n. sensu., Eremini n. trib. and Progryllacridini n. trib.; ten genera: Claudiagryllacris n. gen., Griffinigryllacris n. gen., Gorochovgryllacris n. gen., Ingrishgryllacris n. gen., Rentzgryllacris n. gen., Willemsegryllacris n. gen., Karnygryllacris n. gen., Brunnergryllacris n. gen., Bianigryllacris n. gen. and Hugelgryllacris n. gen.; seven genera groups: Gryllacrae n. group. (placed under Gryllacridini n. trib. comprising ten genera: Caustogryllacris, Eugryllacris, Gryllacris, Lyperogryllacris, Nesogryllacris, Ocellarnaca, Phlebogryllacris, Prosopogryllacris, Willemsegryllacris n. gen. and Xanthogryllacris), Metriogryllacrae n. group. (under Gryllacridini grouped Metriogryllacris, Homogryllacris, Pseudasarca n. stat. and Furcilarnaca), Anancistrogerae (Anancistrogera, Ancistrogera, Angustogryllacris, Aphanogryllacris, Celebogryllacris), Triaenogryllacrae n. group. (under Gryllacridinae only comprising Triaenogryllacris) the next groups under Ametrini n. trib.: Ametrae n. group. (comprising two genera: Ametrus and Pareremus), Apotrechae n. group. (including three genera: Apotrechus, Apterolarnaca and Bianigryllacris n. gen.) and Apteronomae n. group. (comprising two genera: Ametrosomus and Apteronomus). The status of Dictogryllacris reinst. stat., was restored, previously transferred by Gorochov 2003 as subgenus of Capnogryllacris and to Pseudasarca n. stat. as full genus status is proposed. One genera, one subgenus and one fossil species are synonymized: Xiphogryllacris n. syn. (under Hyalogryllacris) and †Gryllacris brevippennis n. syn. (under †Macrelcana ungeri). The subgenus Glolarnaca n. stat. (included under Zalarnaca), is considered as full genus in Gryllacridinae (Gryllacridini). 57 new combinations are proposed, with particular emphasis on Niphetogryllacris, placing 36 of the 43 existing species of the genus: Pissodogryllacris tesellata n. comb., Willemsegryllacris barnesi n. comb. (previously placed under Gryllacris), Afrogryllacris nigripceps n. comb. (previously placed under in Barombogryllacris), Anancistrogera nigroscutata n. comb., A. cornualis n. comb. and A. genualis n. comb. (included by Karny in Caustogryllacris and by Gorochov in the subgenus Pseudolarnaca, here transfered to Anancistrogera), Hugelgryllacris tchancha n. comb. (before in Psilogryllacris), Diaphanogryllacris annandalei n. comb., D. barkudensis n. comb., D. dravida n. comb., D. gravelyi n. comb., Claudiagryllacris finoti n. comb. C. stigmata n. comb., C. lemur n. comb., C. fryeri n. comb., Stictogrtllacris pungens n. comb., S. madagassa n. comb., S. genufuscata n. comb., S. vosseleri n. comb., S. difficilis n. comb., S. paulani n. comb., Stictogryllacris signoreti n. comb., S. indecisa n. comb., S. conspersa n. comb., S. pittarellii n. comb., S. ametroides n. comb., S. jacobi n. comb., S. kilimandjarica n. comb., S. meruensis n. comb.; S. neglecta n. comb.; S. submutica n. comb., Griffinigryllacris reunionis n. comb., G. adelungi n. comb., G. mauritiana n. comb., Karnygryllacris occipitalis n. comb., K. atriceps n. comb., K. brevipennis n. comb., K. humilis n. comb., K. scurra n. comb., K. triocellata n. comb., K. pittarellii n. comb., K. grylloides n. comb., Brunnergryllacris testaceus n. comb. and B. eximia n. comb (previously placed under Niphetogryllacris), Rentzgryllacris sechellensis n. comb. (before in Prosopogryllacris and the three subspecies are treated as full species), Gorochovgryllacris navicula n. comb. (transferred from Brachybaenus), Bianigryllacris trilobus n. comb., B. bilobus n. comb., B. digitatus n. comb., B. fallax n. comb., B. nigrigeniculatus n. comb., B. parvospinus n. comb., B. quadratus n. comb. and B. transversus n. comb. (previously placed under Apotrechus), Hyalogryllacris orthoxipha n. comb. (previously placed under Xiphogryllacris), Afroneanias glauningi n. comb., A. sphinix n. comb. and Ingrishgryllacris brevifalcatus n. comb. (previously placed under Ametroides and Glomeremus respectively). A key to the identification of the subfamilies and tribes is provided, plus historical background of the major taxonomic works on the group and the few contributions on ecology, morphology, and behavior is also done. It also discusses the status of fossil taxa thought to belong to the family. A preliminary analysis of the zoogeography of the family from the parameters of richness, diversity and distribution patterns of different groups studied, and also, some final comments on what has been achieved in this contribution are give, what is missing to the study of gryllacridines to the future and some problems that still affect the taxonomy to genera and species level. Finally, a check list in which all family taxa are included with the new classification is provided, with some comments on their distribution and taxonomic status if necessary.

RESUMO

A new genus of the family Callianassidae, Laticallichirus, is established for "Neocallichirus" grandis Karasawa Goda, 1996, a ghost shrimp species heretofore represented only by fossil materials from the middle to upper Pleistocene of Japan. The newly collected specimens came from two Japanese localities: Numazu, Shizuoka Prefecture (Suruga Bay) and Tosa, Kochi Prefecture (Tosa Bay), included within the known geographical range derived from fossil records. The species identification was based on the close agreement in the cheliped morphology and the known fossil distributions. The new genus is assigned to the subfamily Callichirinae Manning Felder, 1991, and compared with seven genera, Balsscallichirus Sakai, 2011, Callichirus Stimpson, 1866, Callichiropsis Sakai, 2010, Grynaminna Poore, 2000, Michaelcallianassa Sakai, 2002, Lepidophthalmus Holmes, 1904 and Podocallichirus Sakai, 1999, all characterized by the antennular peduncle being longer and stouter than the antennal peduncle. The new genus is characteristic in combination of the following characters: rostrum spiniform; maxilliped 3 devoid of exopod; ischium-merus of maxilliped 3 broadly operculiform; maxilliped 3 ischium devoid of crista dentata; major cheliped devoid of meral hook or associated lobe-like structure; tergites of the pleomeres 3-5 without conspicuous ornamentation; male pleopod 2 biramous, its endopod devoid of appendices interna and masculina; uropodal endopod suboval in shape; telson distinctly wider than long, with shallowly concave posterior margin. The genetic analysis using the mitochondrial 16S rRNA places the new genus as sister to Callichirus Stimpson, 1866, although bootstrap support for major branches is generally low. The newly collected specimens were found in burrows in soft sediments of shallow subtidal zone being accessible at low tide.

RESUMO

An ongoing taxonomic inventory of mycophagous gall midges (Cecidomyiidae) in Sweden has revealed several previously unnamed species of asynaptine Porricondylinae, which are described here on the basis of male adults mostly from Malaise trap catches. The new species are classified and named as follows: Asynapta inflatoides sp. nov., A. rickebasta sp. nov., A. taigensis sp. nov., Camptomyia capitata sp. nov., C. hedmarki sp. nov., C. oldhammeri sp. nov., C. rhynchostylata sp. nov., and Stackelbergiella sikorai sp. nov. Specimens studied here prove the presence of both Asynapta inflatoides and A. taigensis in Finland, and of Stackelbergiella sikorai in Estonia. Other species new to the Finnish fauna are Asynapta thuraui Rübsaamen and Camptomyia ulmicola Mamaev, whereas Asynapta inflata Spungis has to be deleted from the Finnish checklist. Males of two species recorded in Sweden for the first time, and three species whose Swedish distribution is reconfirmed here, are redescribed: Asynapta baltica Spungis; A. inflata; Camptomyia fulva Mamaev; C. piptopori Panelius; and C. ulmicola. New junior synonyms recognized here are Niladmirara Fedotova syn. nov. (of Camptomyia Kieffer) and Asynapta panzari Jaschhof Jaschhof syn. nov. (of A. breviata Spungis). The genitalic morphology of male Asynaptini is reinterpreted to include two pairs of parameres in the ancestral ground pattern. The extraordinary diversity of male genitalic structures found in asynaptine genera is highlighted, along with considerations of how this source of information can be exploited for the benefit of classification. Small-area remnants of ancient, naturally grown forest are shown to support populations of previously unnamed species of Asynaptini.

RESUMO

Morphological structures of several glandulariine genera known to occur only in North America have never been properly described and illustrated. In consequence, status and diagnoses of some potentially key taxa to understand the evolution of the Northern Hemisphere Scydmaeninae remain unclear. Comparative morphological study of Catalinus and Parascydmus is intended to reduce this gap. Examination of type species revealed that both genera belong to glandulariine taxa characterized by the submentum demarcated laterally by sutures. The status as separate genus for Catalinus and Parascydmus is maintained. The most interesting discovery is that the Nearctic Parascydmus resembles most the endemic Japanese Rutaraphes; among other characters, these taxa share a uniquely modified frons and the aedeagus lacking parameres.

RESUMO

Sparsorythus is a genus of Tricorythidae from the Oriental Region. Sparsorythus multilabeculatus Sroka Soldán, 2008 was described based on a male imago from Vietnam. Unknown nymphs and female subimagines of Sparsorythus and male imagines of S. multilabeculatus were collected from Thap Lan National Park, Khon Buri District, Nakhon Ratchasima Province, Thailand. Nymphs and female subimagines of Sparsorythus were associated with male imagines of S. multilabeculatus by analyzing sequences from the DNA barcoding region of the mitochrondrial gene cytochrome oxidase I. Phylogenetic analysis based on Maximum Likelihood indicated that all unknown specimens are conspecific with male imagines of S. multilabeculatus (bootstrap 100% and genetic distance 0-0.004). Male and female nymphs, female subimago and egg are described for the first time. Nymphs each bear a medial emargination on the hypopharynx, one bristle-like process at the base of the left prostheca, and a bifurcate rudimentary gill on abdominal segment VII. The male usually has smudges and light blotches on its forewings; the penis extends to the basal segment of the forceps and reaches to approximately 1/3 of the second segment of the forceps. Forewings of the female subimago have dark colour over more than half of the basal area, and the distal portion of each wing is translucent. The egg has a rounded pole; the polar cap covers approximately 1/4 of the surface; and the surface is covered with hexagonal structures.
