Phryno tibialis (Sun, 1993)

Calozenillia tibialis Sun, 1993: 441 . Holotype male (IZCAS, not examined). Type locality: China, Shanxi, Yicheng, Dahe.

Diagnosis. Male. Scutellum entirely orange or reddish yellow; male femora with blackish gray pruinosity on basal part, yellow on ventrodistal part; vein M with section between crossvein dm-cu and bend subequal in length to that between bend and wing margin; two katepisternal setae; abdominal terga with dense yellowish pruinosity; male vertex approximately 0.3 of head width; antenna with first flagellomere approximately 3.5 times as long as pedicel; male postabdomen with surstylus narrowed on apical half 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. O’Hara et al. (2009) moved this species to Phryno from Calozenillia probably based on the facial and male genital features, which were illustrated in the paper of Sun (1993). This species appears to be very similar to P. koreana , P. nepalensis and P. vetula based on the original description and illustrations (Sun 1993). However, this species is different from the others in having the following morphological features: male femora black on basal part; male vertex approximately 0.3 of head width; two katepisternal setae.

Phryno vetula (Meigen, 1824) ( Figs. 19–21 )

Tachina vetula Meigen, 1824: 399 . Syntypes, published as males (female(s) in MNHN, not examined). Type locality: Europe. See Herting and Dely-Draskovits (1993: 235) for a complete list of synonyms.

A detailed redescription of this species was given by Mesnil (1954: 341).

Diagnosis. Scutellum and legs entirely orange or reddish yellow, but sometimes dark brown on basal part. Vein M with section between crossvein dm-cu and bend 1.1–1.3 times as long as that between bend and wing margin; abdominal terga with dense yellowish or whitish gray pruinosity entirely. Male. Vertex 0.29–0.32 of head width; gena approximately 0.3 of eye height; antenna with first flagellomere rather short, approximately five times as long as pedicel, 3.5–4.0 times as long as wide; male postabdomen with surstylus tapered to apex, apical 1/3 slightly curved ventrally in lateral view, strongly curved inward on apical half and rather broad at base in dorsal view; cerci rounded apically and shorter than surstylus in lateral view. Female. Vertex approximately 0.45 of head width; first flagellomere approximately 4.5 times as long as pedicel.

Body length. 8–9 mm.

Specimens examined. GERMANY. 2 males, 1 female (CNC), Spassart forests, i.1979; UNITED KINGDOM. England: 1 male (BLKU), Biggin Hill, Kent, 19.v.1981.

Distribution. Europe, Russia, Transcaucasia, China (O’Hara et al. 2009).

Hosts. This species is parasitic on lepidopteran larvae that feed on leaves of deciduous trees (e.g., Noctuidae and Geometridae ) (Tschorsnig & Herting 1994).
