Ma, Libin & Zhang, Yalin, 2011, Redescriptions of two incompletely described species of mole cricket genus Gryllotalpa (Grylloidea; Gryllotalpidae; Gryllotalpinae) from China with description of two new species and a key to the known Chinese species, Zootaxa 2733, pp. 41-48 : 47

Gryllotalpa cycloptera sp. nov.

(Figs. A4, B4, C4, D4)

Type material. Holotype male, China: Zhejiang, Tianmu Mountain, 11-October-1999, coll. Liu Xianwei et al. (SEM). Paratypes. male, China: Jiangxi, Lushan, Guling (Ku-ling), 08-Sept.-1934, coll. O. Piel (SEM); male, China: Jiangxi, Lushan, Guling (Ku-ling), 04-Sept.-1934, coll. O. Piel (SEM).

Diagnosis. Male. Slightly large, in medium size. Ocelli less large, rounded and somewhat convex. Pronotum about 1.2 times longer than wide. Tegmen much small and nearly rounded when flattened; harp shaped as reversed triangular; only with c1 but c2, c1 opened from base to tip; radius divided distally, both R1 and R s curved. Stridulatory files sinuate, distinctly curved downward at middle; teeth distributed in the way of a line, dense inside and medially, sparse outside. This specimen with right tegmen over left. Hind wings vestigial and covered by FWs. Hind tibiae armed with three internal preapical spines. Genitalia: sclerotic, colored from light brown to brown. Transverse sclerite (which has been destroyed when dissecting) thick and strong, middle part v-like and very deep; epiphallus peltate, in front view, top rectangular and excurved downward to median on both sides, then slightly constrict downward to bottom; in lateral view, top side oblique with parallel lateral sides; in dorsal view, shaped as triangule; ectophallus paramere shaped as non-convex quadrilateral which is concave at outside medially, internal process of ectophallus paramere straight, shaped as long acute triangle.

Coloration: Body light brown, but dorsal of head, anterior part of pronotum black, abdomen back and dorsal of hind femur colored brown; the fore and media legs in light color and ocelli brown.

Measurements: BL 27, PL 8, PW 6.5, PI 1.23, FWL 5, FWW 2.3, HWL 2.5, HLL 7.5, SAL 2.3, SAW 1.3, SFL 1.3, NST 53.

Etymology: The specific epithet “ cycloptera ” refers to the nearly rounded tegmen of the species.

Remarks: The species is more or less similar to Gryllotalpa orientalis Burmeister and Gryllotalpa formosana Shiraki, 1930 , but can be distinguished by its small tegmen with unique venation and more sclerotic genitalia.
