description: Key to Anurogryllina genera (Modified from Gorochov, 2019 and Cadena-Castañeda & García, 2020)
1. Body apterous or with very short tegmina (visible part of tegminal dorsal field not longer than pronotum), which in male with partly reduced stridulatory apparatus; tympana absent; male genitalia with posterior part of median lophi undivided into a pair of distinct lobes or slightly bilobed....................................................................... 2
‒ Body apterous or with tegmina diverse in length and structure; tympana developed or absent; male genitalia with median lophi divided into a pair of distinct lateral lobes in posterior part..................................................... 3
2. Body with very short tegmina, which in male with partly reduced stridulatory apparatus; male genitalia with psudepiphallus elongate (much longer than wide) and having distinct antero-dorsal lobe curved upwards-backward, and with distal part of rachis long and very thin; ovipositor well-developed................................................ Mexigryllus
‒ Body apterous; male genitalia with pseudepiphallus transverse (wider than long) and lacking distinct anteromedian lobe, and with distal part of rachis short and slightly widened before apical portion; ovipositor rudimentary......... Paranurogryllus
3. Male tegmina with normal stridulatory apparatus or without it; male genitalia with pseudepiphallus long (more than 1.8 times as long as wide) and having distinct anteromedian lobe directed upwards or backwards.................... Anurogryllus
‒ Male tegmina with normal stridulatory apparatus; male genitalia with pseudepiphallus rather short (less than 1.8 times as long as wide) and having rather diverse anterior part.............................................................. 4
4. Male tegmina not reaching middle of abdomen; male genitalia with distinct anteromedian lobe (or a pair of anteromedial lobes) curved backwards or backwards upwards...................................................... Hispanogryllus
‒ Male tegmina reaching distal part or apex of abdomen; male genitalia without distinct anteromedian lobe or anteromedial lobes curved backwards and/or upwards........................................................................ 5
5. Small to medium size (12-15 mm), median lophi longer than the pseudepiphallic parameres, ectophallic fold no divided dorsoventrally........................................................................................ 6
‒ Tiny size (10 mm); median lophi reduced, pseudepiphallic parameres noticeably longer than the lateral lophi, ectophallic fold dorsoventrally divided......................................................................... Atsigryllus
6. Body with white stripes, if not having white stripes, the antennae always have large portions white (between 20 and 30 segments), alternated with black. Median lophi moderately elongated, subtriangular shaped and with a conspicuous medial incision; pseudepiphallic paramere conical, and with rounded apex; ectophallic fold flat in ventral view....... Zebragryllus
‒ Body without white stripes, antennae completely brown. Median lophi short, quadrangular and with a small medial incision; pseudepiphallic paramere with truncated apex; ectophallic fold in ventral view with a groove from base to apex.............................................................................................. Andeogryllus n. gen.
