Type species: Tettix palpatus Stål, 1877 (= Tefrinda palpata).

Composition and distribution. Monotypic genus, whose only species ( T. palpata) inhabits the Philippines (Luzon, Siargao).

Notes. The genus and its sole species are unique among Scelimenini in (I) very narrow vertex (narrower than a compound eye), (II) lack of evident pronotal projections, (III) palpi with folliaceous articles (similar to that of Ophiotettigini), (IV) lateral ocelli between the eyes, (V) conical ventrolateral projections and (VI) obtuse pulvilli of the hind tarsi. Relationship to other Scelimenini genera is not clear. Superficially, Tefrinda resembles Tagaloscelimena, but according to the mentioned morphological characters it could be member of the tribe Criotettigini .
