A remarkable new genus of Iberian troglobitic Trechodina (Coleoptera: Carabidae: Trechinae: Trechini), with a revisited molecular phylogeny of the subtribe
A new representative of the subtribe Trechodina, Iberotrechodes spinosus n. gen., n. sp ., subterranean and known so far from a single cave system of the Cantabrian chain (NW Spain), is described. The external morphology of the new species is highly derived within Trechodina, in particular for the p...
