Studies on phorid flies (Phoridae, Diptera) in Japan : Part I. Key to subfamilies and important genera of Phoridae, and descriptions of six species belonging to five genera

Descriptions of six species of phorid flies belonging to five genera are given in the present paper. These species are as follows : 1. Diploneura (Dohrniphora) cornuta (Bigot, 1857) 2. Diploneura (Diploneura) peregrina (Wiedemann, 1830) 3. Aneurina unispinosa (Zetterstedt, 1860) 4. Stichillus matsumurai Schmitz, 1952 5. Conicera (Tritoconicera) breviciliata Schmitz, 1926 6. Megaselia (Aphiochaeta) spiracularis Schmitz, 1938 Of these, the male of Stichillus matsumurai was described for the first time by the authors, although the female had been described by Schmitz previously. Aneurina unispinosa was found in Hokkaido for the first time in Japan. Diploneura cornuta and Megaselia spiracularis are very common species in Japan, and Diploneura peregrina and Conicera breviciliata are commonly found in Tokyo. Keys to subfamilies and important genera of Phoridae are also given in this paper.
