description: Genus Nannogryllacris Karny, 1937 (Figs 5-7)   
 Nannogryllacris Karny, 1937: 133.   
 TYPE SPECIES. — Gryllacris exigua Brunner von Wattenwyl, 1888.   
 DIAGNOSIS (IN ADDITION TO THE ABOVE- MENTIONED CHARACTERS SHARED WITH AMPHIBOLOGRYLLACRIS). — Size: small; body length: 12.5-20 mm; FIII: 6.2-12 mm; FW: 9-17 mm. Colour: light brown, without clear black drawings (neither on face, pronotum, abdomen, legs); FW veins concolourous with the FW cells. Cerci usually reduced, not much longer than male styli. Mesosternum and metasternum lobes rounded.   
REMARKS  
This genus and the five species belonging to it are omitted in Otte (2000).  
 Nannogryllacris niaoulii Kaltenbach, 1968 is often omitted in available databases.   
 Karny (1937) considered Amphibologryllacris and Nannogryllacris as extremely closely related and gave only colour characters to distinguish them.   
 TENTATIVE KEY TO ADULT NANNOGRYLLACRIS KARNY, 1937 SPECIES Abdominal apex is lacking in N. exigua (Brunner von Wattenwyl, 1888).   
 1. FW with M not visible on the base, fused with R from the base to the FW proximal third (Fig. 7A); male cerci not longer than styli (Fig. 6J); female SGP preceding sternite with a cuneiform posterior projection (Fig. 6D); ovipositor shorter than FIII...................................................................................................................... N. novaguineae   
 — FW with M visible on the base, sometimes lying in contact to R, sometimes anastomosed with R (Fig. 7 C-E); male only known in N. niaoulii (Kaltenbach, 1968) without styli; when known, female SGP preceding sternite unmodified or with a lobiform or furciform appendice, not with a cuneiform appendice; ovipositor shorter, as long as, or longer than FIII........ 2   
 2. FW with Cu simple (not furcated, Fig. 7C, E); head without conspicuous ocelli; when known, SGP preceding sternite unmodified; when known, male SGP without styli; when known, ovipositor much (c. ⅓) longer than TIII........................................................ 3
