Phyllomya angusta Shima & Chao, 1992

( Figs 13 , 22 , 56 )

Phyllomya angusta Shima & Chao, 1992: 637 . Holotype male (IZCAS, examined). Type locality: China, Yunnan, Meilixueshan.

Phyllomya angusta: O’Hara et al. 2009: 41 (Chinese catalog).

Diagnosis. Head almost holoptic in male; all body hairs black; no proclinate orbital setae in male; parafacial with dense, long hairs; antennal pedicel with a long seta almost as long as postpedicel; palpus black; 3 presutural dorsocentral setae; mid tibia with only 1 anterodorsal seta; 3 preapical dorsal setae on hind tibia; male claws and pulvilli long.

Redescription Body length: 6.8 mm.

Male. Terminalia: Sixth tergite entire, without hairs; cerci in dorsal view broad along basal 1/3 and narrowed to apex, narrowly separated along apical 1/2, in lateral view nearly straight along apical 1/2, apex weakly swollen; surstylus nearly parallel-sided in lateral view, obliquely truncated at apex, with several hairs; sclerotized dorsal area of distiphallus flat, membranous apical portion about 1/3 as long as basal sclerotized portion.

Female. Unknown.

Type material examined. Holotype ♂: Meilixueshan [in Chinese] / 3200 m / Deqin [in Chinese] / 22.vii.1982 ( IZCAS).

Distribution. China (Yunnan).

Remarks. This species is known only from the male holotype from southwestern China. It resembles the Japanese species P. aristalis (Mesnil & Shima) in general appearance, such as the head almost holoptic with the gena dense haired, arista long plumose and tibia with 3 apical dorsal setae, but differs from that species for mid tibia with only one anterodorsal setae and male cerci rather parallel-sided along basal 1/3 to 2/3, then evenly narrowed to apex in dorsal view, instead of mid tibia with 2 anterodorsal setae and cerci evenly narrowed from basal 1/3 to apex in P. aristalis .
