Gryllacrididae (Orthoptera: Ensifera) in southern Africa

Abstract

Although Gryllacrididae are a largely southern hemisphere insect family, they are relatively poorly represented in southern Africa, with three genera (Ametroides Karny, 1928, Glomeremus Karny, 1937, and Stictogryllacris Karny, 1937) and ten species and subspecies recorded from the region. All Ametroides and Glomeremus species are wingless while those of Stictogryllacris are long-winged. All species are arboreal and nocturnal, returning by day to characteristically silk-spun shelters between leaves. Here, we present a diagnosis, key to genera, and high-quality images to assist in identification of Gryllacrididae. By compiling all published information in one place, we hope to facilitate future researchers to investigate this poorly known group.
