Genus Claustropyga Hippa, Vilkamaa & Mohrig, 2003

Type species: Corynoptera clausa Tuomikoski, 1960: 43 , 46, figs 9 g, 10 a, 14 c. Literature: Hippa et al. (2003): 469‒511; Vilkamaa & Hippa (2007): 53‒68; Mohrig et al. (2013): 179; Hippa & Vilkamaa (2016): 594‒600.

Diagnostic characters. The genus is characterized by a short and strong apical tooth, not longer than spines (mostly 4 – 10) at the inner side. Gonostylus are mostly short and strong, in some species slightly concaved or more or less winged, outsides with strikingly short hairs in some species. Most species can easily be recognized by a characteristic intergonocoxal area on the ventral side of the hypopygium. Gonocoxites are basely united, forming a broad lobe-like bridge which is richly haired. The apical part of the tegmen is more or less narrowed. Palpus 2- or 3-segmented, mostly with one bristle (rarely with 2‒3) at the basal segment; the sensory area is not deepened. Claws are toothless; posterior wing veins are without macrotrichia; posterior pronotum bare. The genus includes the former Corynoptera clausa group in the sense of Tuomikoski (1960) and Menzel & Mohrig (2000).
