Female Chauliogryllacris, copyright David Rentz.

Belongs within: Stenopelmatidae.

The Gryllacridinae are a group of mostly robust but relatively soft-bodied nocturnal orthopterans that stridulate by rubbing a rasp of pegs on the hind femur against hairs or tubercles on the side of the abdomen. They are often known as ‘leaf-rolling crickets’ due to the practice of some species of tying leaves together with silk produced by the mouthparts, but not all species engage in this behaviour. Rentz (1996) suggested the alternative vernacular name of ‘raspy crickets’ as more representative. The group is most diverse in the tropics and the Southern Hemisphere with only a small number of species in northern temperate regions (Hale & Rentz 2001).

Characters (from Gorochov 2001; Hale & Rentz 2001): Generally robust, 1 to 15 cm in length; usually winged (occasionally brachypterous or apterous). Antennae filamentous, generally as long as or longer than body. Rostrum of head between antennae usually rather wide, not tubercle-like. Fore thoracic stigmata with distinct rudiment of third lobule and rather large hind projection. Tarsi depressed, soft, with three pairs of prominent lateral lobes of more or less widened pulvilli; fore coxae with spine; fore tibiae lacking spines or auditory organs; hind femur with pegs on inner surface, rubbing against tubercles or hairs on opposing sides of abdominal tergites. Male abdominal apex with enlarged ninth tergite. Ovipositor usually well developed.
