Karsch, 1890a. Entom. Nachricht. 16: 61.

Remarks.

-The main characters of the genus are the following ( Karsch 1890a; pers. obs.): head small, fastigium of vertex raised, tuberculated, not contiguous with fastigium of frons, sulcate, first antennal segment clearly larger than others. Eyes round, very prominent, antennae very delicate. Pronotum narrow and compressed, flat above, enlarged posteriorly, anterior margin straight, posterior margin rounded, humeral sinus rounded and deep, lateral lobes longer than high, lower margin rounded. Tegmina narrow, exceeding hind femora, anterior margin rounded, posterior margin sinuous, apex obliquely cut. Hind wings longer than tegmina. Legs very fragile and long. Fore femora compressed, lower margin armed, hind femora thin. Both inner and outer tympana of fore tibiae conchate. Cerci of male short incurved and pointed, subgenital plate more or less bilobed or pointed, styli absent. Tegmina and legs are always narrow and give to the species the long-limbed aspect. The name Tetraconcha derives from the conchate tympana (from Greek tetra = four).
