Caconemobius fori, copyright Alan Cressler.

Belongs within: Grylloidea.

The Nemobiinae, pygmy field crickets, are small ground-dwelling crickets found in moist habitats (Rentz 1996). Members of the tribe Thetellini are flightless and usually associated with coastal habitats such as rocky or coral beaches or mangroves (Otte 1994). Members of the tribe Pteronemobiini, found worldwide, are characterised by the presence of a glandular spur on the hind tibiae in males. The wood cricket Nemobius sylvestris is a species with reduced wings found in forest margins in Europe and northern Africa.

Characters (from Rentz 1996): With or without tegmina. Head with dorsal bristles. Hind tibia shorter than hind femur, with 2-4 internal and external subapical spurs, without spines between spurs, and with three internal and three external apical spurs. Second tarsal segment laterally compressed, without large pads.
