Genus Pseudoxyelocerus nov.

Type species: Pseudoxyelocerus bascharagensis sp. nov.

Etymology: After the similarity with the genus Xyelocerus .

Diagnosis.—Similar to Xyelocerus , from which it differs in having the vein Sc long, parallel, strongly approximate to, but distinctly separated from R; Sc2 present, but very short; Sc1 long, oblique (we follow Rasnitsyn 1996: fig. 5a, who figures no veins Sc, Sc1, and Sc 2 in Xyelocerus ). Further differences concern larger cell [M1] in Pseudoxyelocerus than in Xyelocerus , while cell [2Cu] is about the same size in two taxa. In Xyelocerus veins M and Cu not extended distal of the levels of 3r−m and 2m−cu respectively, instead of being shortly extended in Pseudoxyelocerus . The pterostigma is broader in Pseudoxyelocerus than in Xyelocerus .
