Ten species were identified for phorid flies collected at the Akasaka Imperial Gardens, Tokyo. Most of the species seemed to be common in Japan, but two of them were remarkable. Peromitra fimbriata was described as new to science from mountainous region in Kyushu, Japan, based on a few male specimens (Nakayama & Shima, 2002). Discovery of this species in Tokyo, low altitude in cental Japan, is interesting. Another species, Anticofimbria orientis, is the type species of the monotypic genus Anticofimbria which was described by Schmitz (1951) based on a male specimen caught in Tokyo on 18 June, 1950 by Prof. Max v. Kiienburg. Anticofimbria orientis has never been caught again since the first male specimen. Many males and some females of this species were caught by a Malaise trap in this survey. Anticofimbria orientis has long strong bristles on the anepisternum and lacks wing vein Ra+s in both sexes. It was confirmed that the genus Anticofimbria was different from the genus Apocephalus, from these characters. The genitalia and proboscis of the female of A. orientis were asymmetric in structure (Fig. 1).
