Chiasmus Mulsant & Rey

Remarks. This genus can be distinguished by the sharp foremargin of the vertex and dorsal ocelli ( Fig. 10 a) and short subgenital plates without macrosetae ( Fig. 10 h). In addition to C. niger and C. alatus, Pruthi also described C. mustelinus (Distant) from Pakistan but we are unable to confirm this identification. In addition, there is some confusion with respect to the identity of mustelinus as the genitalia figures given by Pruthi do not match in all respects a syntype in the BMNH. There are two syntypes of the latter species in BMNH and according to Pruthi two in ZSI.

Chiasmus sp. (Plate 1, h; Fig. 10 ).

Material examined. Pakistan: 73, 9Ƥ, Sindh Prov., Tando Jam, 12.xi.07, I. Khatri.

Remarks. This species may be C. facialis (Distant) from India, which is a very variable species in the BMNH collection. In addition, the Pakistan specimens identified as Chiasmus alatus Pruthi , by Fatema et al (1995: 255) may be this species and from its original figures, C. jagdishi Pruthi from India, may be a synonym of C. facialis .
