IDENTIFICATION OF GROUND CRICKET (ORTHOPTERA: GRYLLIDAE: NEMOBIINAE) WITH REFERENCE TO THEIR SOUND PRODUCING STRUCTURE

Abstract

In the present work three species of the Genus Pteronemobius Jacobson and Bianchi of sub-family Nemobiinae, family Gryllidae, are described on the basis of male sound producing structures i.e. tegmina, plectrum and the stridulatory file. The venations of tegmina, number of oblique veins, size of harp, size of apical field and shape and structure of mirror emerge as important characters to distinguish males of sub-family Nemobiinae from other related taxa from Pakistan.
