Phryno jilinensis (Sun, 1993)

Calozenillia jilinensis Sun, 1993: 443 . Holotype female (IZCAS, not examined). Type locality: China, Jilin, Jingyue.

Diagnosis. Female. Scutellum and legs entirely orange or reddish yellow; vein M with section between crossvein dm-cu and bend approximately 1.8 times as long as that between bend and wing margin; three katepisternal setae; abdominal terga with whitish gray pruinosity.

Remarks. Sun (1993) described this species and C. tibialis from China as members of Calozenillia in having the following combination of characters: compound eye densely setulose; parafacial bare; facial ridge with some short setae on lower part. O’Hara et al. (2009) transferred these species to Phryno because they probably have a pair of short and weak apical scutellar setae and a bulged facial ridge according to the original descriptions and illustrations.

This species appears to resemble P. brevicornis , P. katoi and P. vetula in the wing venation (vein M with section between crossvein dm-cu and bend approximately 1.8 times as long as that between bend and wing margin) and coloration (scutellum entirely yellow). Male postabdominal characters are important for species identification of this genus due to the peculiar features. However, since P. jilinensis was described only from the female sex, it may be very difficult to distinguish this species from other members of this genus.
