The Pardisomus species from Costa Rica, with descriptions of four new species and one larva (Coleoptera: Curculionidae: Baridinae).

Abstract

The neotropical weevil genus Pardisomus Pascoe is redefined based on morphological character states of Agalmatus Kuschel and association of six species with Pentagonia Bentham (Rubiaceae). Procholus Desbrochers, Anambates Casey, Piazambates Voss and Agalmatus are new synonyms of Pardisomus. New combinations with Pardisomus are 1) from Agalmatus: P. brasiliensis (Kuschel), P. geniculatus (Hustache), P. nigritarsis (Kuschel), P. panamensis (Kuschel); 2) from Embates: P. cleroides (Champion); 3) from Lydamis: P. squamipes (Kirsch); 4) from Peridinetus: P. rufescens (Hustache); 5) from Piazambates: P. piazuroides (Voss); and 6) from Procholus: P. biplagiatus (Desbrochers). Four new species of Pardisomus are described from Costa Rica: P. albescens, P. amotus, P. byrrus and P. suffuscus. The larva of putative P. biplagiatus is described for the first time.
