Comments:
1. BECHYNÉ (1950) examined the types of both Ch. lobicollis and Ch. mandarina
and concluded that they were conspecific. I compared the type specimens of
Taeniosticha poricollis (lectotype is designated below) with both original description
and recent interpretation of Ch. lobicollis (FAIRMAIRE, 1887 and BECHYNÉ,
1952 respectively) and came to a conclusion that Ch. lobicollis is a new junior
synonym of T. poricollis. According to MOTSCHULSKY (1860), the type locality of
T. poricollis is “Mongolie”, while Ch. lobicollis and Ch. mandarina were described
from China (Peking and Tai-Yuen-Fou, respectively). I also had at my
disposal specimens of Ch. aeruginosa poricollis from China only. This subspecies
differs from its allies in the shape of pronotum: lateral sides are nearly
straight, being narrowed anteriorly and of the same colour as dorsum: bronzy
black, shining in both sexes. This colour variation is not known from Mongolia
(MEDVEDEV 1980). Therefore, I think that “Mongolie” in MOTSCHULSKY (1860)
refers to China.
