Cholovocera brevicornis Johnson, 1977

Johnson (1977: 123) described two new species which he placed in the genus Cholovocera , both with exactly the same collecting data, i.e., locality, altitude, date and collector. The first species was Cholovocera afghana Johnson, 1977 , which we have dealt with in detail above. Johnson (1977: 124) named his second species as Cholovocera brevicornis . We have examined the holotypes of both these species and concluded that, while Ch. afghana is a valid taxon and correctly placed in the genus Cholovocera , “ Cholovocera ” brevicornis not only belongs to another genus but is also a junior synonym.

The brief description of “ Ch. ” brevicornis includes the following features: length as 1.25 mm, colour reddish-yellow, eyes twice as long as broad, short antennae, shape of pronotum, fine punctuation, width as 0.72 mm, and last visible sternite not impressed. The host is given only as “ant”.

Our study of the holotype of “ Ch. ” brevicornis revealed that it had six ocelli on each ocular area ( Fig. 24D View Fig ), while all the other species of Cholovocera have only one ( Fig. 24E View Fig ); this diagnostic generic character, in addition to its small size, its general habitus ( Fig. 24C View Fig ) and its association with ants of the genus Pheidole , indicate that it belongs to the genus Displotera . Furthermore, our detailed comparison of non-sexual features of the holotype of “ Ch. ” brevicornis against two female syntypes of D. beloni showed that they belong to the same taxon. Therefore, we propose that Cholovocera brevicornis Johnson, 1977 should be regarded as a junior synonym of Displotera beloni ( Wasmann, 1899) .
