| Abstract: | Abstract. A new Oriental fishfly genus, Sinochauliodes gen.n. , is described, including four species: S. fujianensis ( Yang & Yang, 1999 ) comb.n. , S. griseus ( Yang & Yang, 1999 ) comb.n. , S. maculosus sp.n. and S. squalidus sp.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. |
