Paris, France (Accepted 28 January 1993) The genus Trypelimorplw. is revised with th e eight currently recognized species described or rc-desc ri bed. Four new speci es are described and seven new synonymies are proposed. Within T rypcti morphi ni sensu (1982), ev idences for the monophyly of each genu s are selected, but Ca/fro/tlmatissus is transFerred to the Cixiopsini . Monophyly of Trypetirnorphini, restricted to Trypelinwrpha and Ommali.\·sus, is discussed. A key is given for the following Trypelimorphu species: (1) 1'. fellestrata Cosln ( :: 1'. pilosa H orv1ith, syn. n.); (2) T. biermani Dammennan ( :: 1'. biennani Mu ir, syn . n.;:: T ,:hina (Wu), syn. n.::: T. fo rmosana Ishiha ra, syn. n.); (3) Tjaponica Ishihara (= 7: koreana Kwon and Lee, syn. n.); (4) T.

Paris, Ahhough Trypetimorpha itself has no species of proven economic importance, this study of its systematics a nd phylogeny is intended as a contribution to the understanding of the group as a whole. Morphological studies on the genus have also been published recently (Bourgoin and Huang. 1 990, 1991).
