Abstract
Discovery of slides bearing type material of Neotonchus punctatus provides a basis for an analysis of the genus Neotonchus Cobb, 1933 and a related new genus, Gomphionema. Characteristics, unique and common to a rich supply of species of these genera, necessitate the erection of a new subfamily within the Cyatholaimidae for the accommodation of the genera. Neotonchus punctatus, the type species, is redescribed and four new species and one new combination are added to the genus, namely N. phaleratus n. sp., N. chamberlaini n. sp., N. lutosa n. sp., N. melotridus n. sp., and N. corcunda (Gerlach, 1956) n. comb. syn. Comesa corcunda. The genus Comesa Gerlach, 1956 is synonymized with Neotonchus Cobb, 1933. The new genus Gomphionema is created for G. typica n. sp. (type species), G. fellator n. sp., and G. compacta (Gerlach, 1957) n. comb. syn. Neotonchus compactus. Keys to, and descriptions of, all species in the subfamily are provided.Keywords
