Genus Nousera Navás, 1923

Nousera Navás, 1923: 5 . Type species: Nousera gibba Navás, 1923: 5 . Monotypy.

Diagnosis. Nousera is similar to Glyptobasis in having the distinct triangular projection on the anal area of forewing and it can be distinguished by the presence of narrow wings with rhomboid-shaped pterostigma (Figs 10A–B, 11E–H).

Note. Navás (1923) described Nousera based on a single species, Nousera gibba from India, and latter Sziráki (1998) treated Nousera as a junior synonym of Pseudoptynx van der Weele, 1909, but the later genus was recognized as a junior homonym of an Aves genus, Pseudoptynx Kaup, 1848 by Oswald and Penny (1991). Consequently, Sziráki (1998) placed Nousera gibba and Pseudoptynx furcifer in Nousera . Ábrahám & Mészáros (2006) reinstated Pseudoptynx and proposed a new name, Ascapseudoptynx for Pseudoptynx furcifer, which is distinguishable from Nousera based on the longer male abdomen in comparision with the hind wing and the presence of long bifurcate projection on tergum 2 (van der Weele 1909: fig 161 III).

Currently Nousera includes two species, i.e., Nousera gibba Navás, 1923 from China, India, Laos, Malaysia and Thailand, and N. herczigi Ábrahám & Mészáros, 2006, only known from the type locality in Pakistan. A key to species of Nousera is constructed based on present material collected from Pakistan.
