Abstract

A new monotypic genus, Distostylus Webb (Diptera: Therevidae), based on a new species, irwini Webb, is described from specimens collected on the Caribbean island of Dominica. An hypothesis of the placement of the new taxon is generated based on a matrix of 30 morphological characters. This genus is associated with the Lindneria genus group and shows some affinities to the amber fossil species Ambradolon grimaldii Metz & Irwin.
