A new species and a new replacement name in Chinese Cheilosia (Diptera, Syrphidae)

摘要

A new species, Cheilosia senia sp. n. from China, is described. The new species is closely related to Ch. grahami Bark., differing in the structure of male genitalia, gray pruinosity on mesonotum, and less elongate face. The genus Endoiasimyia is ranked as a subgenus of the genus Cheilosia. Cheilosia (Cheilosia) fornlosana Shir. is a junior secondary homonym of Cheilosia (Endoiasimyia) fornlosana (Shit.). A new name, Ch. (Ch.) shirakiatla Bark., nom. n., is proposed for Ch. (Ch.) formosana.
