Coarazuphium lundi (Carabkiae: Zuphiini), a new Brazilian troglobitic beetle, with the designation of a neotype for C. pains Alvares Ferreira, 2002

摘要

In this paper, we describe Coarazuphium lundi sp. nov., from a single male specimen collected in Gruta 06L cave located in the municipality of Prudente de Morais (Minas Gerais state, Brazil). The two most striking differences between C. lundi and other species of the genus is the presence of two pairs of posterior supraorbital setae and the elytra shape with parallel, not rounded sides. Coarazuphium pains Alvares & Ferreira 2002 is an endemic species restricted to a few caves at the Bambul Carbonatic Group in the midwest of Minas Gerais state, Brazil. The holotype of C. pains was unfortunately lost in 2010, due to a fire that destroyed almost the entire zoological collection at the Butantii Institute, Salo Paulo state in Brazil. In recent years, several species of the genus have been described and compared to C. pains only based on its paper description, clearly prompting the need for the C. pains neotype designation. In order to provide a necessary standard for comparison, a neotype is designed for this species based on the material collected from the best approximation of the type locality (caves). Lastly, we also provide a brief discussion on the presence of eyespots of C. cessaima, originally described as blind.
