The first Strigocis Dury (Coleoptera, Ciidae) from the southern Neotropical region and a provisional key to world species

Strigocis vicosensis Lopes-Andrade sp. n. is described based on specimens from a single locality (type locality: Viçosa, state of Minas Gerais, southeastern Brazil), being the southernmost record of a Strigocis Dury species. Diagnostic to this new species are the dorsal vestiture consisting of stout yellowish bristles, pronotal punctures separated from each other by at least 0.75× puncture-width and sutural flange of elytra not diverging near apex. Males have both frontoclypeal ridge and anterior pronotal margin produced forward and emarginated at middle forming two small subtriangular plates, and a small abdominal sex patch. Among the New World Strigocis, it most resembles S. bilimeki (Reitter), of which images of male terminalia, as far as ventral and dorsal SEM images of males are also provided. The morphological limits of Strigocis are briefly discussed and redefined, and a provisional key to the world species is provided
