Abstract:

A new Neotropical genus Parapsammodius gen. n. with type-species Psammodius integer BATES, 1887 is proposed. One new species, P. pseudointeger sp. n. is described and the following species are given in new combinations: Parapsammodius integer (BATES) comb. n. and P. bidens (HORN) comb. n., both transferred from Odontopsammodius GORDON & PITTINO and P. puncticollis (LECONTE) comb. n. transferred from Ataenius HAROLD. A key is included to separate the four species in the genus. Altogether nine species belonging to six genera of the Eupariini-Psammodini complex are discussed, the structures of their mouthparts are illustrated, eight types of the epipharyngeal sense organs are presented for the first time. Cladistic analysis was performed to indicate tribal classification of the new genus.
