Conchopus


Conchopus is a genus of flies in the family Dolichopodidae. Species of the genus are found in Japan, China, Taiwan, the Hawaiian Islands, and Wake Island. The species Conchopus borealis is also an introduced species in North America and South America. Members of the genus live exclusively in the intertidal zone of rocky shores. The genus is sometimes considered a synonym of Thambemyia, but is considered a valid genus by some authors.

Taxonomy and species

Takagi originally divided the genus into seven species groups. According to Masunaga et al. and Masunaga & Saigusa, the genus can be divided into two clades: one containing the rectus species group, and the other containing all other species groups, for which the authors intended to propose a new genus. The latter clade they also consider to be the sister group of Thambemyia.
