Phylogeny of the subfamily Chauliodinae (Megaloptera: Corydalidae), with description of a new genus from the Oriental Realm

A new Oriental fishfly genus, Sinochauliodesgen.n., is described, including four species: S. fujianensis (Yang & Yang, 1999) comb.n., S. griseus (Yang & Yang, 1999) comb.n., S. maculosussp.n. and S. squalidussp.n. A cladistic analysis based on adult morphological characters clarified the phylogenetic status of the new genus and allowed the reconstruction of the intergeneric relationships of the subfamily Chauliodinae. Two main clades within Chauliodinae were recognized from the cladistic analysis. The Asian fishflies, together with the two Nearctic genera, Chauliodes and Nigronia, formed a monophyletic lineage, and the new genus was assigned as the sister group to the genus Parachauliodes. The biogeography of the Asian fishflies is discussed.
