oa Journal of the Entomological Society of Southern Africa - Functional morphology of the stridulatory apparatus of Acanthoplus speiseri Brancsik (Orthoptera: Tettigoniidae, Hetrodinae)

 

Abstract

The functional morphology of the stridulatory apparatus of Acanthoplus speiseri Brancsik was studied and geographic variation in the structure investigated. The stridulatory apparatus comprises a pair of modified and highly reduced mesothoracic wings or tegmina that serve solely as sound producing organs, and their operating muscles. These forewings are oval in shape and have a parchment-like consistency. Each tegmen bears a file of cuticular teeth on the CuP vein and a hardened edge (plectrum) underneath. The left sound producing organ overlaps the right both at rest and during stridulation.
