Genus Natalogryllus Gorochov, gen. n.

Etymology: The name refers to KwaZulu-Natal and the genus Gryllus .

Type species: Cophogryllus eshowensis Otte, 1987 (KwaZulu-Natal, environs of Eshowe and Pietermaritzburg) .

Diagnosis: Medium-sized crickets with hemispherical head, comparatively small eyes and wide area between antennae (distance between antennal cavities approximately equal to width of eye and almost twice as wide as scape); body completely apterous; tympana absent; fore and middle legs neither long nor thickened (not adapted to digging); hind legs typical of Gryllini (distinctly adapted to jumping); abdominal apex without projection. Male genitalia (Figs 32–40) with rather short and wide epiphallus having a pair of large lateral hind lobes and smaller median lobe between them; ectoparameres rather short and not thin, partly membranous; each of them with a single elongate sclerite of more-or-less simple shape; ectoparameral mesal lobes absent; endoparameres moderately long and narrow, without distinct apodemes; spermatophore sac small and simple, without additional loops or distinct apodeme; virga moderately long, weakly curved near distal part of spermatophore sac, without ligament (semi-sclerotised structure connecting virga with endoparameres in some Gryllini). Ovipositor not shortened and with acute digging apical part.

Figs 32–40. Natalogryllus gen. n., _: (32–34) N. eshowensis; (35–37) N. escourtensis; (38–40) N. trichardti (after Otte 1987). Genitalia dorsally (32, 35) and ventrally (34, 40); their distal half ventrally (33, 36, 39), laterally (37), and dorsally (38). Abbreviations: as in Figs 1–5 and 23–31.

Species included: Type species (Figs 32–34); N. escourtensis (Otte, 1987) ( Cophogryllus; KwaZulu-Natal, environs of Cathedral Peak and Bulwer) (Figs 35–37); N. trichardti (Otte, 1987) ( Cophogryllus; Limpopo Prov., Soutpansberg) (Figs 38–40).

Comparison: The most important differences of the new genus from the previous genera reviewed here are given in the key. From all other representatives of the tribe Gryllini, the new genus differs in the following combination of characters: both sexes completely apterous; tympana absent; epiphallus with 3 hind lobes; each ectoparamere with a single simple sclerite, its mesal lobe absent; endoparameres without distinct apodemes; spermatophore sac small and simple; virga weakly curved near distal part of spermatophore sac, without ligament; ovipositor not shortened.
