The genus Desmometopa Loew (Diptera, Milichiidae) of Japan

Abstract

The Japanese species of the genus Desmometopa Loew are revised. Of three known species from Japan, two species reported as D. tarsalis Loew and D. tristicula Hendel are proven to be D. microps Lamb and D. sordida Fallen, respectively. Two species, D. m-nigrum (Zetterstedt) and D. varipalpis Malloch are newly recorded from Japan. Short redescriptions of five species are added with illustrations of head, pleuron and male genitalia. A key to the Japanese species is presented.
