Phryno yichengica Chao & Liu, 1998

Phryno yichengica Chao & Liu in Liu & Chao et al., 1998: 231. Lectotype male (IZCAS, not examined), by fixation of Chao & Liu in Liu, Chao & Li (1999: 350). Type locality: China, Shanxi, Yicheng, Dahe.

Diagnosis. Male. Scutellum entirely orange or reddish yellow; male femora with blackish gray pruinosity on basal 1/2–3/5, yellow on ventrodistal 2/5–1/2; vein M with section between crossvein dm-cu and bend subequal in length to that between bend and wing margin; abdominal terga with dense yellowish pruinosity entirely, black on mid dorsal longitudinal portion of third abdominal tergum; two katepisternal setae; male vertex approximately 0.3 of head width; antenna with first flagellomere approximately 5 times as long as pedicel and 3.5 times as long as wide; male postabdomen with surstylus tapered to apex in lateral view, strongly curved inward on apical half and rather broad at base in dorsal view; cerci nearly straight and subequal in length to surstylus in lateral view.

Remarks. Judging from the original description and illustrations, this species may be easily distinguished from other members of Phryno treated in this study by the following combination of characters: scutellum entirely yellow; male femora black on basal part; male vertex approximately 0.3 of head width; two katepisternal setae; vein M with section between crossvein dm-cu and bend as long as that between bend and wing margin. However, it may be difficult to distinguish this species from P. tibialis.
