RESUMO

In this study, we conducted a summer sampling of carabid beetles in eastern Australia to identify their associated parasitic mites. Here, we describe three new species of the genus Eutarsopolipus from under the elytra (forewings) of three native carabid species (Coleoptera: Carabidae): Eutarsopolipus paryavae n. sp. (pterostichi group) from Geoscaptus laevissimus Chaudoir; Eutarsopolipus pulcher n. sp. (leytei group) from Gnathaphanus pulcher (Dejean); and Eutarsopolipus chlaenii n. sp. (myzus group) from Chlaenius flaviguttatus Macleay. We further provide an identification key of the world species of pterostichi and leytei species groups as well as closely related species of the myzus group possessing similar characters including short cheliceral stylets. The significant diversity of Eutarsopolipus recovered here suggests that the current knowledge about Australian podapolipid mites (specially Eutarsopolipus) is still in its infancy and deserves further study.

RESUMO

BACKGROUND: Meloidae (blister beetles) are known to synthetize cantharidin (CA), a toxic and defensive terpene mainly stored in male accessory glands (MAG) and emitted outward through reflex-bleeding. Recent progresses in understanding CA biosynthesis and production organ(s) in Meloidae have been made, but the way in which self-protection is achieved from the hazardous accumulation and release of CA in blister beetles has been experimentally neglected. To provide hints on this pending question, a comparative de novo assembly transcriptomic approach was performed by targeting two tissues where CA is largely accumulated and regularly circulates in Meloidae: the male reproductive tract (MRT) and the haemolymph. Differential gene expression profiles in these tissues were examined in two blister beetle species, Lydus trimaculatus (Fabricius, 1775) (tribe Lyttini) and Mylabris variabilis (Pallas, 1781) (tribe Mylabrini). Upregulated transcripts were compared between the two species to identify conserved genes possibly involved in CA detoxification and transport. RESULTS: Based on our results, we hypothesize that, to avoid auto-intoxication, ABC, MFS or other solute transporters might sequester purported glycosylated CA precursors into MAG, and lipocalins could bind CA and mitigate its reactivity when released into the haemolymph during the autohaemorrhaging response. We also found an over-representation in haemolymph of protein-domains related to coagulation and integument repairing mechanisms that likely reflects the need to limit fluid loss during reflex-bleeding. CONCLUSIONS: The de novo assembled transcriptomes of L. trimaculatus and M. variabilis here provided represent valuable genetic resources to further explore the mechanisms employed to cope with toxicity of CA in blister beetle tissues. These, if revealed, might help conceiving safe and effective drug-delivery approaches to enhance the use of CA in medicine.

RESUMO

We present the first formal record of the twig-girdler Psyllotoxus griseocinctus Thomson, 1868 (Cerambycidae: Lamiinae: Onciderini) attacking the rose, Rosa sp. (Rosaceae) in Southern Brazil. We provide photographs of the damage P. griseocinctus causes to the plant, as well as morphological descriptions of the immature stages and molecular diagnostic tools to identify this species. Additionally, we provide a modelled map with the known and potential distribution of P. griseocinctus and new host records for three plant species: the common walnut tree, Juglans regia L. (Juglandaceae); the cambucá tree, Plinia edulis (Vell.) Sobral (Myrtaceae); and the cherry tree, Prunus cf. serrulata Lindl. (Rosaceae).

RESUMO

Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) is an insect popularly known as the red flour beetle, it is widely distributed worldwide and can cause serious damage to stored grains. Chemical control is the most used method for managing this pest, however, some substances are toxic to mammals and the environment. Therefore, the development of new effective and safe insecticides is necessary. Essential oils (EOs) can be considered as a potential alternative in the development of pesticides due to their physicochemical properties and varied effects against insects. In the current study, was determined the fumigant toxicity and biochemical effects of selected essential oils against T. castaneum. The 23 selected EOs were characterized by GC-MS and their fumigant lethal concentrations were determined. An exploratory Cluster analysis was performed to find a relationship between fumigant toxicity and chemical composition. Finally, the inhibition of the catalytic activity of acetylcholinesterase (AChE), glutathione S-transferase (GST) and catalase (CAT) was evaluated using protein homogenates obtained from T. castaneum. The results indicated that EOs with the highest fumigant potential were those with greater diversity in their composition, while the least active EOs presented mainly monoterpenes. The most active EOs were those obtained from Foeniculum vulgare and Zanthoxylum monophyllum with LC50 values of 16.23 and 18.54 µL/L air respectively. Regarding the inhibition of the enzymatic activity of the 23 EOs evaluated at 500 µL/L, only two caused an inhibition greater that 50% on AChE, which corresponded to EOs from Piper nigrum and Rosmarinus officinalis. Likewise, EOs from C. sinensis, Piper aduncum and Zanthoxylum monophyllum were the only ones able to inhibiting GST activity by more than 50%. Respecting CAT inhibition, 7 EOs caused and inhibition greater than 50%, highlighting those from Lavandula angustifolia, C. sempervirens and Eucalyptus sp. These results show that the EOs evaluated in this study seems to be a promising bio-controller of T. castaneum since have high fumigant toxicity and exert different mechanisms of action.

RESUMO

New data on taxonomy of several Afrotropical species of Harpalus Latreille, 1802 are provided, with special attention to the species recorded outside the African continent. Two new species from East Africa are described: H. pseudoasemus sp. n. from Tanzania and Kenya (type locality: Oldonyo Dambu, 15 km north of Arusha, Tanzania), and H. merkli sp. n. from Ethiopia (type locality: Chercher). Harpalus impressus Roth, 1851, H. asemus Basilewsky, 1947, H. fuscoaeneus Dejean, 1829, H. australasiae Dejean, 1829, and H. parvulus Dejean, 1829 are re-described based on the types and additional material, and the diagnostic characters of Hypharpax australis (Dejean, 1829) are given. Harpalus australasiae sensu Larochelle Larivire, 2005 (non Dejean, 1829) is treated as conspecific with the Afrotropical H. parvulus which was introduced to Australia and New Zealand. The genus Anisochirus Jeannel, 1946, stat. resurr. is restored for most of the Madagascan and Mascarene species included previously in Harpalus. The members of this genus differ from those of Harpalus in having glabrous paraglossae. The status and taxonomic position of Anisochirus is discussed. The following synonymies are proposed: Harpalus impressus Roth, 1851 = H. sundaicus Schauberger, 1933, syn. n., and H. asemus Basilewsky, 1947 (January 30) = H. hamasiensis G. Mller, 1947 (September 30), syn. n. Lectotypes are designated for H. impressus and H. fuscoaeneus.

RESUMO

A new species of the genus Mesomeloe (Meloidae) is described from Qatar on the north-eastern coast of the Arabian Peninsula. Mesomeloe ottomerkli sp. nov., which is currently only known from the type locality, was previously identified as Meloe (Mesomeloe) coelatus. Both the morphological and molecular variability of M. coelatus across its wide distribution range are studied to determine the level of congruence between the morphological and genetic differentiation of M. coelatus and the new species. Mesomeloe ottomerkli is distinguishable from all other congeneric species in various traits: it presents a body tegument and appendages that are black in colour and shiny in appearance; an elytral surface absent of impressed longitudinal shallow ridges; a pronotal surface absent of depressed areas and longitudinal midline; and a pronotal base that is slightly arcuate. In addition, males of M. ottomerkli have antennae that gradually widen towards the apex; protarsomeres with a brush patch of yellowish setae on the ventral surface of the first two segments; genitalia in which the gonostyli, in lateral view, become slenderer towards the apex and an aedeagus that is relatively wide and rounded in the distal portion. The distribution records of M. coelatus are also updated and summarized.

RESUMO

A new fossil tiger beetle species, Goriresina fungifora gen. n., sp. n. (Coleoptera, Cicindelidae), is described from Eocene Rovno amber. The new genus belongs to the subtribe Iresiina, tribe Cicindelini, due to the glabrous head, the labrum with six submarginal setae (latero-basal setae very long) and two apical teeth with notch between them, the glabrous and globular pronotum, the lack of setae on the metepisternum and metepimeron, as well as on the visible parts of abdominal sternites, the single long seta each on the fore- and mesotrochanter. The new species is characterized by the long and moderately convex labrum, two clypeal setae, the elongate and apicad converging elytra with an angularly, but smoothly rounded apex, the small and sharp sutural spine, the probable presence of an apical portion of the elytral humeral spot, a slightly sinuate, transverse medial fascia with an extended and downward directed apical portion, and a slightly transverse basal portion of the apical spot. This is the first record of a tiger beetle in Rovno amber and only a fourth well-preserved Cicindelidae from fossil resins.

RESUMO

Scaphidiinae (Coleoptera, Staphylinidae) comprises more than 1800 described species in 46 genera. With 766 described species and subspecies, Scaphisoma Leach is the most diverse genus of this subfamily and is distributed almost worldwide. A total of 38 species are recorded from the Neotropical region and only six are known from Brazil. In this paper, Scaphisoma pandemum von Groll Lopes-Andrade, sp. nov. is described on the basis of 44 specimens collected from polyporoid fungi in two Atlantic Forest remnants in Viosa, Minas Gerais, Southeast Brazil. We provide images of adult male and female and their dissected parts, information and photographs of host fungi and comparative notes.

RESUMO

We review the taxonomy and provide identification resources for the species of Cryphalus Erichson, 1836 from the Hawaiian Islands. Five species are present, Cryphalus brasiliensis (Schedl, 1976) new country record, Cryphalus mangiferae Stebbing, 1914, Cryphalus negrosensis Browne, 1979, Cryphalus sylvicola (Perkins, 1900), and Cryphalus trypanoides (Beeson, 1935) (= Cryphalus mollis Schedl, 1955 syn. nov.). Additionally, while reviewing the species, two species not present in Hawaii are resurrected from synonymy with C. sylvicola: Cryphalus pini (Hopkins, 1915) stat. res. and Cryphalus swezeyi (Schedl, 1942) stat. res. None of the Hawaiian species are endemic, and most are known from most major Pacific islands, and presumed introduced. Cryphalus negrosensis is a likely recent introduction and is a frugivorous scolytine, collected from a wide range of fruits, and found breeding in Artocarpus altilis fruit pulp.

RESUMO

The larva of Stenophylax fissus (McLachlan 1875) is redescribed, illustrated, and compared with morphologically similar Limnephilidae larvae from the Iberian Peninsula. In addition, the sequence of the mtCOI gene in the barcode region of one individual is reported. Likewise, the barcode and the conspecificity between two larvae and one female of the non-sequenced species S. crossotus are given. In addition, the high genetic diversity among S. sequax populations is highlighted, suggesting a complex of cryptic species. Finally, a diagnostic matrix of the known larvae of Stenophylax species from the Iberian Peninsula is provided.
