Females of Traumatomutilla André (Hymenoptera: Mutillidae) are organized into 14 species groups; 136 of the 138 Traumatomutilla taxa known from females were studied. Of these species groups, only the inermis species group was adequately established and diagnosed in the literature (Casal 1969). The remaining newly established species groups are as follows: americana, auriculata, bellica, bifurca, diabolica, gemella, indica, integella, juvenilis, quadrinotata, tabapua, trochanterata, and vitelligera. Diagnoses and lists of included species are provided for each species group. Eighty-three new country records are provided for 49 species.
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.
Neotropical Xiphocentronidae may have arrived in South America from Central America in the late Miocene or via the Greater Antilles land bridge during the Oligocene. This would give from 10 to 30 Mya of diversification of the family in South America. However, only 11 species were previously known from the Andean foothills. In this study, five new species are described from Peru, four of Xiphocentron (X. ashaninka sp. nov., X. harakbut sp. nov., X. matsigenka sp. nov., X. yine sp. nov.) and one of Machairocentron (M. amahuaca sp. nov.). The new species are most similar to species described from the Yungas of Argentina, and the Pacific dominion of Colombia and Venezuela. The association with species from the Pacific may suggest a species divergences prior to the major Andean uplift and the Amazon basin formation. The spine-like setae on the basal region of the inferior appendage of Xiphocentron were recognized as topologically homologous to the setal brushes on the ventral projection of Caenocentron. Furthermore, based on the morphology of male and female genitalia of Machairocentron, a mating position different from that described for Psychomyiidae is inferred.
Four new species of Xiphocentron (Antillotrichia) Brauer, 1870 from the Atlantic forest are diagnosed, described and illustrated. All of them have a small mesal sclerite and a set of spines, differing in size, density and position, on the inner face of the inferior appendage. Moreover, tergum IX varies mostly in the shape of the posterior margin. Four species are described as new for science. Xiphocentron (Antillotrichia) copacabana sp. nov. is distinguished mainly by the projected basoventral margin of the inferior appendage, the spines are clustered in two regions and the quadrate posterior region of tergum IX. Xiphocentron (Antillotrichia) maracanan sp. nov is differentiated by the inferior appendage, with a strongly angled apical region of 90º. Xiphocentron (Antillotrichia) redentor sp. nov. differs by the inferior appendage, with a linear row of thick spines, and the tergum IX, with a posterior margin forming smoothly rounded lobes. Xiphocentron (Antillotrichia) tijuca sp. nov. is diagnosed by the subbasal region of the preanal appendage, which is markedly projected medially, and by the inferior appendage, which is thin subapically, enlarged apically and strongly bent dorsad.
The Neotropical Distictus Townes, 1966 is diagnosed, redescribed and its species revised. A neotype is designated for the type species, D. tibialis (Brullé, 1846). The genus is characterized mainly by having the body subcylindric; clypeal margin with median tooth; areolet medium-sized, pentagonal, with crossvein 3r-m distinct; first metasomal tergite short and stout, with anterolateral tooth. Distictus aurantium Santos & Aguiar, 2008 is shown to lack some of these character states and is transferred to Mallochia Viereck, 1912. A total of 12 valid species are recognized, ten of which are new: D. apaensis sp. nov., D. ardens sp. nov., D. asterios sp. nov., D. ateles sp. nov., D. caligaris sp. nov., D. commatus sp. nov., D. daelus sp. nov., D. notabilis sp. nov., D. paratibialis sp. nov. and D. terrosus sp. nov. Other valid species are D. tibialis and D. mexicanus Kasparyan & Ruíz-Cancino, 2005. All species are described and illustrated. New distribution records, maps and separate keys for females and males of the species are provided.
The Brazilian endemic irroratus species group of the genus Inca (Scarabaeidae, Cetoniinae) is defined and described. This species group is composed of Inca irroratus Chevrolat, 1833 and two new species: I. axeli sp. nov. and I. neglectus sp. nov. One new synonym is proposed: I. irroratus Chevrolat, 1833 = I. burmeisteri Burmeister, 1844 syn. nov. To guarantee nomenclatural stability, a neotype is designated for I. irroratus and a lectotype for I. burmeisteri. A key to all species of Inca and a map with the distribution of the irroratus species group are 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.
taxia tibialis Schaeffer, 1908 (Coleoptera: Cerambycidae: Lamiinae: Pteropliini) is transferred to Bisaltes (Bisaltes) Thomson, 1868 (Apomecynini), new combination; the female is described for the first time. This extends the range of the genus, previously only known as far north as Costa Rica, to southern Texas. Bisaltes (Bisaltes) obliquatus Breuning, 1940 is found to be conspecific with Bisaltes (Bisaltes) uniformis Breuning, 1939, new synonymy, and recorded from Argentina and the Brazilian state of São Paulo. The holotypes of Esthlogena pulverea Bates, 1866, and Bisaltes posticalis Thomson, 1868 (currently, both synonyms of Bisaltes (Bisaltes) pulvereus) are illustrated for the first time. The holotype of Bisaltes (Bisaltes) bimaculatus Aurivillius, 1904, as well as ventral and lateral habitus of this species are illustrated for the first time and it is newly recorded from the Brazilian state of Santa Catarina.
