Diagnosis.

Very close to Cremnops desertor (Linnaeus, 1758). The traditionally used differences for separation are not sufficient and, consequently, it was synonymised by Sharkey (1996). Both species are very variable in colour, especially the extension of the dark parts of the wing membrane is variable and thus useless for diagnosis. Neverthe less, it is possible to separate the West Palaearctic typical specimens of Cremnops desertor from the East Palaearctic and Oriental specimens (including Cremnops atricornis ) by the relative length of the fore tarsus of the females. In Cremnops desertor the fore tarsus is distinctly longer than the fore tibia and (including claws) about as long as the tibia in Cremnops atricornis . The Vietnamese specimens have the first tergite 1.5-1.8 times as long as its apical width (up to 2.2 times in East Palaearctic specimens according to Sharkey (1996)) and the vertex is yellowish-brown (Fig. 113).
