Terpnistriella n. gen.

Figs 10A–10H

Species type of the genus: Terpnistriella bredoi n. sp., here designated.

Description. Head without fronto-genal carinae. Fastigium of vertex compressed, narrower than first antennal segment, sloping steeply to frons, sulcate above. Eyes round, prominent, wider than subocular groove. Pronotum straight along anterior margin, without median carina; lateral carinae visible in posterior part, mainly after pronotum excision; surface smooth. Fore coxae with spine. Fore and mid femora unarmed. Hind femora with some large and broad-based ventral spines. Fore tibiae with closed tympanum on inner and open on outer side. Fore and mid tibiae with dorsal spurs on outer margin. Hind tibiae with three apical spurs on each side. Both pairs of wings fully developed. 10th abdominal tergite of male unmodified. Male subgenital plate without styli.

Remarks. Even if Terpnistria Stål, 1873 has the open tympanum on the inner side of the fore tibiae, Terpnistriella n. gen. is seemingly related to the former, from which main differences are the absence of frontogenal carinae, the pronotum margins not raised, closed tympana on anterior tibiae, and second pair of wings coloured. Thus, it is tentatively placed in the tribe Terpnistrini .

Etymology. The name Terpnistriella is a diminutive of Terpnistria .
