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.
