2. Genus Hemelytroblatta Chopard, 1929

Type species. Hemelytroblatta cypria Chopard, 1929 .

Diagnosis. From Heterogamodes distinguished by the subgenital plate with strong bristles only along the hind margin; from other Palaearctic genera without apical spine on the fronttibia distinguished by the structure of the right phyllomere (Type 2); Nymphrytria (Mononychoblatta) also has a Type 2 phallomere but differs by having only one tarsal claw and a special kind of armament of the hindtibia.

Male characters. Wings: fully developed or, rarely, strongly shortened and modified, tegmina with or without a subcosta lobe.—Femur armament: frontfemur usually without an apical spine, in some species with a strongly reduced spine, mid- and hindfemur with or without an apical spine.—Tibia armament [1.8.0][n.7.n][n.7.n].—Tarsal arolia: present or absent.—Subgenital plate: with strong bristles only along the posterior margin, posterior border mostly with a shallow asymmetrical excavation, styli present or absent.—Right phallomere: Type 2.—Supraanal plate: very short, posterior border slightly convex or straight ( Fig. 15F ).—Cercal tricholiths:>5 per anulus.

Subgenera: Hemelytroblatta and Mollidentoblatta .
