A new decticine Ctenodecticus thymi n. sp. from the NE of the lberian peninsula (Orthoptera, Tettigoniidae)

Abstract

A new species of the genus Ctenodecticus Bolívar, 1876, Ct. thymi n. sp. from the lberian peninsula is described. The species is similar to Ct. masferreri Bolívar, 1894 and Ct. granatensis Pascual, 1978. The male cerci in Ct. thymi n. sp. are longer than broad, similar to Ct. granatensis and different from Ct. masferreri, in which cerci width and length are similar. Regarding the fernales, the subgenital plate of the Ct. thymi n. sp. has two fossae situated laterally near the margin, in an intermediate position with respect to the position of the other two species. This is the first case on the lberian peninsula of a species showing intermediate rnorphological characters in a genus where all species are very different, and suggests the existence of other undescribed species.
