A new genus of Psychodini (Diptera: Psychodidae) from the Neotropical region.

A new genus of Psychodini, Wagneromyia gen. nov. is described, based on examination of males from the State of Acre in the Brazilian Amazon.

A new genus and new species of Sycoracinae (Diptera: Psychodidae) from the Neotropical region with keys to the extant genera of the subfamily and males of Neotropical species of Sycorax.

Sycoracinae is a small subfamily of Psychodidae with only 51 known species. Three genera are currently accepted for the subfamily: Aposycorax, with one species restricted to the Andean region; Parasycorax, with four Neotropical and one Philippines species; and Sycorax, with wide global distribution. A new genus is proposed for five northern Andean species previously described for Sycorax; a diagnosis and new interpretations of male terminalia characters are provided.

Description of fourty four new species, taxonomic notes and identification key to Neotropical Trichomyia Haliday in Curtis (Diptera: Psychodidae, Trichomyiinae).

Trichomyia Haliday in Curtis is distributed worldwide, except in Antarctica. The Neotropical region has the greatest known species richness of Trichomyia, with 76 described species, compared with five in the Nearctic region, nine in the Palearctic, five in the Afrotropical region, six in the Oriental region, and 46 in the Australasian region. Two morphological groups within the genus have been previously recognized: Group A, comprising species with four clearly differentiated palpus segments; and Group B, comprising species with three palpus segments, as well as a group of species with four palpus segments but with the two basal segments not fully articulated (partially fused).
