A New Species Closely Related to Phorbia fascicularis TIENSUU (Diptera, Anthomyiidae)

Phorbia subfascicularis, sp. n., is described on the basis of material from Japan, Korea and Sweden. It was once misidentified as Phorbia fascicularis TIENSUU by SUWA (1974, 1983), having a peculiar tuft of long setae on the male cercal plate as seen in the latter, from which it is distinguishable by the male terminalia with different details. P. fascicularis sensu FAN et al. (1988) may also be referable to the present new species. In the new species are recognized two forms, which are, however, treated as mere variants.
