The Simuliidae (Diptera) of Sri Lanka. Descriptions of additional species of Simulium (Simulium), with a key for Sri Lankan species in the subgenus and a checklist for the country

Abstract

This is the fifth and final paper in a series treating the Simuliidae of Sri Lanka, and it contains a checklist of the species in the country. In this paper are described three new species of Simulium (Simulium): all stages of Simulium subpalmatum and Simulium cruszi (except the larva) and the male and pupa of Simulium paranubis. The female, male, and pupa of Simulium (Simulium) consimile and S. (S.) striatum are redescribed and the larva of S. (S.) consimile is described for the first time. Taxonomic comparisons are made with related species and keys are provided to separate the eight Sri Lankan species in the subgenus.
