Two new species of Deltosoma Thomson, 1864 are described from French Guiana: D. humeralis sp. nov. and D. fernandezi sp. nov. Deltosoma lacordairei Thomson, 1864 is redescribed based on examination of the holotype. A study of the aedeagi of these three species was conducted. Dorsal habitus photographs of both sexes, ventral photographs of males, and aedeagi photographs are provided.
Kempfidris : a new genus of myrmicine ants from the Neotropical region (Hymenoptera: Formicidae)
(2014)
The new genus Kempfidris gen. nov. is described based on the workers of a single species, K. inusualis comb. nov., from Brazil, Ecuador, and Venezuela. Kempfidris inusualis comb. nov. was originally described by Fernández (2007) and provisionally placed in Monomorium awaiting a better understanding of the internal relationships in Myrmicinae. Kempfidris gen. nov. has a series of distinctive morphological characters including the mandibular configuration, vestibulate propodeal spiracle, propodeal carinae, and cylindrical micro-pegs on the posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII. This last trait appears to be autapomorphic for the genus.
A new species of coffee stem and root borer from Colombia is described: Plagiohammus colombiensis, sp. nov. (Coleoptera: Cerambycidae: Lamiinae). The new species differs from other species of the genus Plagiohammus Dillon and Dillon by the yellow pattern of spots on the elytra, the morphology of the antenna and pronotum as well as characters of the male genitalia. A key to species of Plagiohammus is provided. This study examines the current situation of the new species of coffee stem and root borer in Colombia. Information on its biology and damage to the coffee plantations is presented.
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.
Two new species of Eburiini (Coleoptera, Cerambycidae, Cerambycinae) are described from Mexico (Guerrero): Susuacanga boteroi; and Eburia (Eburia) girouxae. Both are included in previous keys.
The present work provides the first record of the genus Dinotrema Foerster, 1862 in the Neotropical region. Four new Neotropical species are described and illustrated: D. multiareolatum Peris-Felipo sp. nov., D. plaumanni Peris-Felipo sp. nov., D. subbidentatum Peris-Felipo sp. nov., and D. teutoniaense Peris-Felipo sp. nov. The following new combinations are suggested for Nearctic species: Dinotrema angusticornis (Fischer, 1969) comb. nov., D. armillariae (Fischer, 1969) comb. nov., D. bucculatricis (Fischer, 1969) comb. nov., D. caudatulum (Fischer, 1969) comb. nov., D. clayensis (Fischer, 1969) comb. nov., D. communis (Fischer, 1969) comb. nov., D. disstriae (Fischer,1969) comb. nov., D. pauperum (Fischer, 1969) comb. nov., D. saileri (Fischer, 1969) comb. nov., D. shannoni (Fischer, 1969) comb. nov. and D. sylvaticae (Fischer, 1969) comb. nov. An identifi cation key of the all New World Dinotrema species is provided.

(Coleoptera, Cerambycidae, Cerambycinae)
(2017)
