A contribution to the taxonomy of the genus Pelecium Kirby (Coleoptera: Carabidae: Peleciini)
(2024)
Pelecium Kirby, 1817 is a neotropical genus of flightless carabid beetles comprising 34 species, distributed from Panama to middle Argentina. Most species of Pelecium are known from short series and few localities, in some cases only from the holotype. Male and female abdominal terminalia are not described for the majority of the species, a situation that makes it difficult to describe new species or to study intraspecific variation. Here, we describe nine new species based on individuals from Brazil: Pelecium buckupi sp. nov., P. fistulosus sp. nov. and P. zaguryi sp. nov. from the Centre-West region, P. belloi sp. nov., P. chrissquirei sp. nov., P. straneoi sp. nov. and P. zophos sp. nov. from the Southeast region, and P. balli sp. nov. and P. grossii sp. nov. from the South region. We also provide new distributional records and descriptions of abdominal terminalia for twelve species: Pelecium atroviolaceum Straneo & Ball, 1989, P. bolivianum Straneo & Ball, 1989, P. cyanipes Kirby, 1817, P. helenae Straneo & Ball, 1989, P. laeve Chaudoir, 1854, P. negrei Straneo, 1962, P. drakei Quedenfeldt, 1890, P. punctatostriatum Straneo, 1970, P. purpureum Straneo, 1955, P. rotundipenne Schaum, 1860, P. striatum Straneo, 1955 and P. violaceum Brullé, 1838.
Described, illustrated and discussed is a strikingly distinct new species of the scarabaeine genus Anomiopus Westwood, A. apuskispay Figueroa and Edmonds, from the Chanchamayo montane forest region of eastern Peru. It is a close relative of the recently described A. pishtaco, also from eastern Peru. Both species are noteworthy because of the bizarre form of the male clypeus, which bears extravagantly developed marginal teeth.
A new genus and two new species of Argentine Rhinotragini
(Coleoptera, Cerambycidae, Cerambycinae)
(2017)
Rhopalessa irwini sp.nov. and Rhinion parkeri gen. nov., sp. nov. (Coleoptera, Cerambycidae, Cerambycinae, Rhinotragini) are described from Argentina. A key to species of Rhopalessa is provided.
An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synonymized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico and Guatemala, Eupogonius giesberti, is described. The following new combinations are established: Fallaxdesmis unicolor (Buquet, 1857) and Eupogonius piperita (Bates, 1855). Illustrations of A. mannerheimii, Fallaxdesmis unicolor, and the holotypes of A. hirticornis, A. vestita, A. unicolor, A. piperita and Eupogonius giesberti are included.
A new species of ant-mimicking spider of the subfamily Castianeirinae, Myrmecotypus rubrofemoratus Perger and Rubio, new species (Araneae: Corinnidae), is described from the Pre-Andean area of the Bolivian orocline. Adults of M. rubrofemoratus new species resemble the carpenter ant Camponotus femoratus Forel, 1907, which is considered one of the most aggressive ants in the world.
