Phyllomya formosana Shima, 1988

( Figs 17 , 26 , 60 , 77 , 109 )

Phyllomya formosana Shima, 1988: 11 . Holotype male (BLKU, examined). Type locality: Taiwan, Chiai Hsien , Alishan, 2300 m.

Phyllomyia formosana: Shima & Chao 1992: 640 ; Richter 2004: 368 (tachinids of Russian Far East); O’Hara et al. 2009: 41 (Chinese catalog).

Diagnosis. Head dichoptic in both sexes; 2 proclinate orbital setae; antennal pedicel with a seta almost as long as pedicel; arista short plumose; 1 presutural and 0–1 postsutural acrostichal setae; 2 katepisternal setae; mid tibia with 2 anterodorsal setae in male, 3 in female; hind tibia with 3 preapical dorsal setae; male claws and pulvilli longer than 5th tarsomere; male 5th abdominal sternite with strong sharp spines on postero-interior corner of posterior lobe.

Redescription. Body length: 5.1–8.5 mm.

Male. Terminalia: Sixth tergite entire, concave on mid-dorsal portion, without hairs; surstylus slender, weakly tapered to apex, with several hairs; cerci in dorsal view rather narrow, mid-dorsal suture distinct, narrowly separated along apical 1/4, weakly curved ventrally along apical 1/ 4 in lateral view; pregonite flat; postgonite almost reaching apex of epiphallus; distiphallus with dorsal sclerite curved dorsally on posterior margin, distal membranous portion slightly shorter than dorsal sclerite.

Type material examined. Holotype ♂: Taiwan / Alishan , 2300 m / Chiai Hsien / 5.vi.1970 / H. Kurahashi ( BLKU) . Paratypes. Taiwan: 5 ♂♂, same locality as holotype, 3, 4, 5.vi.1970, H. Kurahashi & K. Nishida ( BLKU, KMNH) ; 2 ♂♂, 2 ♀♀, Alishan , 2400 m, 12–16.vi.1965, T. C. Maa & K. S. Lin ( BPBM) ; 1 ♂, Chiai Hsien, Tata- chianampu to Paiyunshanchuan , 6.vii.1985, H. Shima ( KUM) ; 1 ♂, Nantou Hsien, Meifeng to Tsuifeng , 2200–2300 m, 25.iv.1981, K. Ohara ( KUM) .

Distribution. China (Taiwan).

Remarks. This species closely resembles P. elegans from Sichuan, but differs from it for its narrow gena, 1 presutural and 1 postsutural acrostichal setae on the thorax and long male claws.
