Abstract

The western Nearctic genera Neothremma and Farula are assigned to the family Uenoidae, previously comprising only the type genus Uenoa from Asia; a new genus Sericostriata with S. surdickae n. sp. from western North America is also added to the family. Traditionally assigned to the Limnephilidae where they have been always anomalous, Neothremma and Farula are shown to share many synapomorphic larval characters with Uenoa; under close examination, characters of the adults support this relationship. Familial and generic diagnoses are provided, reflecting the revised composition of the Uenoidae. Generic keys to adults, larvae, and pupae are given; species are briefly reviewed and keys given to adults; Uenoa arcuata n. sp. is described from Assam, Uenoa janetscheki Botosaneanu is placed as a junior subjective synonym under U. hiberna Kimmins, and Neothremma laloukesi Schmid as a junior subjective synonym of N. alicia Dodds and Hisaw. Phylogenetic relationships among the genera are considered. This study is an instructive example of the importance of larvae in providing data for the systematics of Trichoptera.

Résumé

Les genres ouest Néarctiques Neothremma et Farula sont assignés à la famille Uenoidae, qui n'incluait auparavant que le genre type Uenoa d'Asie; on y ajoute également le genre nouveau Sericostriata avec S. surdickae n. sp. d'Amérique du Nord occidentale. Les genres Neothremma et Farula appartenaient traditionnellement aux Limnephilidae parmi lesquels ils étaient aberrants, mais on montre ici qu'ils partagent plusieurs caractères synapomorphiques larvaires avec Uenoa; à l'examen attentif, les caractères des adultes appuient l'établissement de cette relation. On fournit les diagnoses familiale et génériques révisées des Uenoidae. On fournit aussi des clés génériques des adultes, larves et pupes; les espèces sont passées brièvement en revue et des clés des adultes fournies; on décrit Uenoa arcuata n. sp. de Assam, Uenoa janetscheki Botosaneanu est considéré comme synonyme junir subjectif de U. hiberna Kimmins, et Neothremma laloukesi Schmid comme synonyme junior subjectif de N. alicia Dodds et Hisaw. On examine les realtions phylogénétiques entre les genres. Cette étude constitue un exemple instructif de l'importance des larves comme source de données dans la systématique des Trichoptera.
