Malthesis is a Cantharidae genus with a history of ambiguous systematic placement, being sometimes classified within Malthininae and currently placed in Chauliognathinae, sometimes as a probable synonym of Chauliognathus. Part of the problem is a complete lack of knowledge about the identity of their type species, M. ater, from Colombia. The current generic placement is based on the identity of the subsequently described Malthesis species which, in turn, have never been compared with M. ater. One specimen belonging to the type series of M. ater, here designated as the lectotype, has been located at the Zoological Museum of M. V. Lomonosov State University (Moscow, Russia) and the identities of the species and genus could finally be assessed. Here, M. ater is re-described in detail based on the study of the afore mentioned lectotype and additional specimens from Colombia. The morphological study of the species confirms that most of the subsequently described species are indeed congeneric with M. ater and enables a reliable placement of the genus within Chauliognathinae: Chauliognathini. In addition, a fully updated catalog of all the 38 currently valid species and subspecies of Malthesis is given to ease their future taxonomic studies.

Insetos Do Brasil: Diversidade E Taxonomia

View full text Add to dashboard Cite

Os membros da Ordem Coleoptera são conhecidos popularmente como besouros. Diferentes famílias são conhecidas por nomes populares particulares para cada região. Com distribuição cosmopolita, a ordem constitui o grupo maior e mais diverso de organismos do reino Animal, com cerca de 380 mil espécies descritas (Lawrence & Britton 1994; Ślipiński et al. 2011), que representam cerca de 35% do total de insetos. Em termos comparativos, o número de espécies de besouros excede o de plantas vasculares ou de fungos e é cerca de 90 vezes maior que o de mamíferos. São registradas cerca de 188 famílias no Mundo. No Brasil, já foram registradas pouco mais de 33 mil espécies em 115 famílias. Estima-se que o número real de espécies existentes esteja entre 1-12 milhões de espécies no mundo (Erwin 1982), com cerca de 130 mil no Brasil. O fator mais importante no sucesso de Coleoptera parece ser a evolução dos élitros, a forte esclerosação das partes expostas do corpo, presença de criptonefrídeos e especializações relacionadas a fitofagia. O principal efeito dessas estruturas está relacionado à proteção e a melhora nos mecanismos que reduzem a perda de água (Crowson 1981).

“…Within the Neotropical fauna of Cantharidae Imhoff, 1856, there are two particularly diverse and taxonomically difficult genera, Discodon Gorham, 1881, with nearly 400 currently valid species, and Chauliognathus Hentz, 1830, with over 450 (Delkeskamp 1977;Constantin 2015Constantin , 2016. While the taxonomic problems relating to the latter are gradually being tackled in some recent publications (Biffi 2016;Constantin 2016), Discodon still remains poorly studied. Only two regional revisions exist: that of Constantin (2015) dealing with the fauna of French Guiana, and the much older and now heavily outdated one by Champion (1915) dealing with Central America.…”

Discodon tricolor (Guérin-Méneville, 1832) was thought to be a common species widely distributed in the Atlantic Forests of Brazil, yet showing morphological and chromatic variations. After examination of a large number of specimens from different regions of the Atlantic Forest biome, we found that Discodon tricolor actually represents a complex of many similar and sometimes sympatric species. Thirteen species in this complex are recognised as valid: Discodon tricolor, D. neoteutonum sp. nov., D. vanini sp. nov., D. obscurior Pic, 1906 stat. nov., D. lineaticorne sp. nov., D. aurimaculatum sp. nov., D. marginicolle sp. nov., D. tenuecostatum sp. nov., D. nigrocephalum Pic, 1949, D. tamoio sp. nov., D. viridimontanum sp. nov., D. crassipes Wittmer, 1952, and D. testaceipes Pic, 1930 stat. nov. The species Discodon albonotatum Pic, 1906 is confirmed as a synonym of D. tricolor, while the subspecies D. albonotatum obscurior and D. albonotatum testaceipes are elevated to specific status. The subgenus Acanthodiscodon Wittmer, 1952 is synonymised with Discodon Gorham, 1881. All the species are described and illustrated in detail and an identification key is provided. Despite being chromatically similar, the species show major morphological differences in their aedeagus and antennal structures, suggesting that they do not form a monophyletic clade. A potential mimicry ring involving these species of Discodon as well as other members of Cantharidae, Lampyridae, Cerambycidae and Belidae is discussed. Comments are made on the conservation of these species and their habitats within the Atlantic Forest biome.
