A review of the Neotropical species of the shore-fly genera Orasiopa and Pectinifer (Diptera: Ephydridae)

Mathis, Wayne NCosta, Daniel N. RMarinoni, Luciane

Species of two genera of the tribe Discocerinini from the Neotropics are reviewed with an emphasis on the fauna from Brazil. The two species, Orasiopa (Reymontopa ) mera (Cresson, 1939) and Pectinifer aeneus (Cresson, 1918), are described, illustrated and new occurrence data are provided. Phylogenetic relationships of these two genera into the tribe are discussed. To facilitate identification of these species, we have included diagnoses of the Discocerinini and both genera and have also provided an annotated key to the New World genera in this tribe. We have also provided illustrations, photographs, and scanning electron micrographs of external structures and of structures of the male terminalia for included species.(AU)
