A new genus and species of Placusini from a high mountain in Mexico

Collection: Pensoft Publishers

Keywords: Aleocharinae · Topics: Coleoptera Taxonomy and Distribution, Invertebrate Taxonomy and Ecology, Lepidoptera: Biology and Taxonomy

A new genus and species are described from the Cofre de Perote volcano, in the state of Veracruz, Mexico. Although the new genus is very similar to Placusa, it presents tergite VIII completely modified to form a horn, in both females and males, in addition to other differences in mouthparts. A map and illustrations are provided, as well as an identification key to the genera of Placusini. No morphological characters are apparent to separate Kirtusa Pace from Euvira Sharp in our genus key. The specimens of the new genus were collected using Lindgren and cross traps baited with a mix of semiochemicals: ipsenol, ipsdienol and lanierone.
