Studies on the species of Fanniidae (Diptera) from Japan VI. Two new species closely related to Fannia lineata (Stein) and two newly recorded species from Japan

摘要

Two new species of the genus Fannia Robineau-Desvoidy (Diptera: Fanniidae), Fannia cana sp. nov. and F. rokkoensis sp. nov. are described from Japan. The former specimens were reared from bird's nests, and the latter occurred in mushrooms. Both are members of the glaucescens subgroup of the canicularis group, and are very closely allied to Fannia lineata (Stein). F. pusio (Wiedemann) and F. femoralis Stein are newly recorded from Japan. Both are members of the pusio subgroup of the canicularis group,and native to the Nearctic and Neotropical regions.
