Cratomorphus leoneli: A new firefly from Mexico (Coleoptera: Lampyridae: Cratomorphini)

Abstract

Cratomorphus Motschulsky, 1853 includes 38 species restricted to the Neotropical region. Based on adult males from Mexico, Cratomorphus leoneli sp. nov. is herein described from the states of Oaxaca, Campeche and Chiapas. We place the new species in Cratomorphus' group IV, which includes species with the posterior border of sternite VIII medially produced. The new species can be distinguished from other species of the group IV by the clypeus subquadrate, posterior margin of pygidium bisinuate and posterior margin of sternite VIII with an apically obtuse median projection. Illustrations of habiti and diagnostic traits are provided, along with an identification key and a distribution map for the group IV species.
