Abstract

The taxonomy and systematics of the Neotropical long-horned caddisfly genus Brachysetodes Schmid are reviewed. Illustrations, synonymies, diagnoses, and distribution maps are provided for each species. Keys to the genera of Neotropical Leptocerinae and to males and females of the 10 Brachysetodes species are included. The larval and pupal stages of Brachysetodes forcipatus Schmid are described and illustrated for the first time; the larva possesses a unique set of heavy setae on the dorsal sclerite of abdominal segment IX and the dorsal plate of the anal prolegs; both features are diagnostic for the genus. A phylogeny of the species of Brachysetodes is proposed; two species, Brachysetodes bifidus Schmid and B. major Schmid, are included in the genus as species incertae sedis.
