The Bolivian species of Polyrhaphis Audinet-Serville, 1835, (Coleoptera, Cerambycidae, Lamiinae) are reviewed and illustrated, with P. skillmani new species described. A key is presented to the six species recorded from Bolivia (P. angustata Buquet, 1853; P. argentina Lane, 1978; P. gracilis Bates, 1862; P. pilosa Lane, 1965; P. spinosa (Drury, 1773); and P. skillmani Wappes and Santos-Silva, new species). Their collection localities, based on recently identified specimens examined by the authors, are plotted to show the distribution of species, and displayed next to an ecoregion map of Bolivia to illustrate biogeographical information for Polyrhaphis.
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.
Two Neoibidionini from Bolivia are described as new: Neocompsa schneppi sp. nov. and Tropidion nancyae sp. nov. The new species are compared to closely related species and previous keys by Martins and Galileo (2007, 2009) are modifi ed to include them. Illustrations of dorsal, ventral and lateral habitus, as well as head structures are included for both species. Comments are also included on color and pattern variation of each species.
Abstract. Six new species of Coleoxestia Aurivillius, 1912 (Cerambycidae, Cerambycinae, Cerambycini) are described: C. clarkei from Bolivia; C. chemsaki and C. eyai from Peru; C. fragosoi and C. rafaeli from Brazil; and C. hovorei from Ecuador. Coleoxestia rachelae Eya and Chemsak is also newly recorded from Peru (new country record). Dorsal, ventral and lateral illustrations along with illustrations of various other structures are provided for each of the new species. In some cases, existing key couplets by Eya and Chemsak (2005) or Martins and Monné (2005) are modifi ed to help separate a new species from similar existing species. A reproduction of the general descriptive terminology for the head, prothorax and antennomeres of Coleoxestia, from Fragoso (1993), is also included in the illustrations.
A new Mexican species of Ochraethes Chevrolat, 1860 (Coleoptera, Cerambycidae, Cerambycinae, Clytini) is described: Ochraethes skillmani Wappes, Santos-Silva and Botero. Plocaederus mirim Martins and Monné, 2002 (Cerambycini) is redescribed and its female is figured for the first time. New geographical records in Plocaederus Dejean, 1835 are also 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.
Adesmus martinsi (Coleoptera, Cerambycidae, Lamiinae, Hemilophini), a new species from Bolivia, is described, illustrated, and included in a previous key. The new species displays gender dimorphism in the pubescent pattern and in anatomical structure. Thus, Adesmus becomes the second genus recorded in the Hemilophini to have visual chromatic dimorphism.
Chiquitano gen. nov. Chiquitano volcanesensis sp. nov., Compsibidion achiraensis sp. nov. and Compsibidion amboroensis sp. nov. (Coleoptera: Cerambycidae: Cerambycinae: Neoibidionini) are described from Bolivia. Notes on Rhysium Pascoe, 1866 and Rhysium bimaculatum Pascoe, 1866 are provided, and Brechmoidion separatum Martins and Galileo, 2007 is transferred to Rhysium. Keys to species of Compsibidion Thomson, 1864, Brechmoidion Martins, 1969 and Rhysium Pascoe, 1866 are also provided.
Two new species of Corimbion Martins, 1970 are described from Bolivia: Corimbion kuckartzi and Corimbion ledezmae. A previous key to the South American species of Corimbion (Martins 2009) is herein modified to include the new species. Dorsal, ventral and lateral habitus illustrations, as well as variation in color and dorsal pattern for C. kuckartzi, are also presented.
