NOTES ON CARBONARIA SPECIES GROUP OF GENUS FANNIA ROBINEAU-DESVOIDY (DIPTERA: FANNIIDAE), IN CHINA

Abstract  The present paper deals with the Fannia carbonaria species group (Diptera: Fannidae) in China. Eight species are recorded, 2 of them are described as new to science, i.e. F. antilocera sp. nov. and F. tauricornis sp. nov., and F. imperatoria Nishina 2002 is recorded for the first time in China. Fannia antilocera sp. nov. is most closely related to F. minutipalpis (Stein, 1895), but can be identified by the third antennal segment 2.5 times as long as broad, scutum with brownish-grey, hind femur with a row of pv setae only at basal half. F. tauricornis sp. nov. is very close to F. capricornis Xue, 1996, but is separated on the third antennal segment 3 times as long as wide, basicosta yellow, legs dark brown, the first sternite with hairs, surstylus without expansion on median dorsal; bacilliform process with 2 short processes. In addition, F. tauricornis sp. nov. is fairly related to F. trigonfera Chillcott, 1961, F. japonica japonica Nishida, 1974, F. japonica amamiensis Nishida, 1975, but sets apart by several distinctive characters: cereal plate with longer arm of outside projection, surstylus without expansion on median dorsal, and bacilliform process with 2 short processes. The paper also reports the characters of the F. carbonaria species group. The group as a whole can be recognized by the hind femur without rows of pv setae at apex, the mid tibia with 2 ad and 2 pd setae and the single strong prealar seta.
