Type locality: Sri Lanka. Deposited at the Natural History Museum (BMNH), London, U.K. (not examined). Measurements. Male (n=3): BL 12.32±0.70, HL 1.87±0.10, HW 3.33±0.08, PL 2.19±0.37, PW 3.56±0.16, FWL 6.99±0.20, FWW 3.82±0.13, MTL 2.81±0.06, HFL 6.71±0.09 Description. Male. Body sized medium in Gryllinae species. Head longer than pronotum. Occiput somewhat broad and flatten, vertex slightly inclined. Frons somewhat convex and about 1.5 times of antennal scape. Antennal scape transverse wide and almost shaped as rectangular. Clypeus depressed and conspicuously lower than frons; Postclypeus (top portion of clypeus) longitudinally narrow and band-shaped. Mandible strong. End section of maxillary palpus equal to the length of the third; end section of labial palpus almost equal to the total length of remainder two. Pronotum transverse and almost two times wider than length.Anterior margin of pronotum slightly concave and posteriorly straight, with lateral margins slightly inclined and fold down. Lateral lobes of pronotum almost flatten with anterior and posterior slightly concave. Basal field of elytra very small and as 2/3 length of pronotum. Oblique veins two. Diagonal vein nearly straight. Mirror obviously longer than width, somewhat rectangular-like but bottom margin pointed round; dividing vein separating hind portion almost triangular-like. Apical field nearly equal to the length of mirror. Hind wings present and uncovered portion obviously longer than cercus. Cercus long and longer than hind tibia. Outer tympana large and longitudinal oval-like; inner tympana rather small and oval-like. Hind tibia almost equal to the length of hind femur. Subapical spurs six pairs and inner proximal one always absent. Coloration. Body colored brown and ornamented with dark brown on head and pronotum. Occiput light brown and ornamented with six fine longitudinal stripes colored yellowish-brown. Area between eyes dark brown and a thin yellowish-brown line between lateral ocelli. Areas between frons and clypeus dark brown, but median ocellus yellowish-brown and a longitudinal fine stripe under median ocellus which colored yellowish-brown. Pronotum dark brown and distributed yellowish-brown spots on the middle and posterior; lateral lobe of pronotum dark brown with bottom margin yellowish-brown. Elytra yellowish-brown and hind wings almost white. Abdomen dorsally and laterally dark brown and ventrally yellowish-brown, but subgenital plate and cercus colored brown. Fore legs almost yellowish-brown and hind legs colored darker, hind femur ornamented with oblique stripes outside. Genitalia. Epiphallus without media lobe, lateral lobes far from each other and jointed by a transverse bridge. Inner margin of epiphallic lateral lobe straight. In lateral view, lateral lobes upward pointed and acute apically. Ectoparamere developed and, in dorsal view, the tips forked. In lateral view, ectoparamere curved dorsally and always touching epiphallic lateral lobes. Females Very similar with male. Apex of ovipositor slightly smooth (Figs. 1C, G).

This species was used to identified as Tartarogryllus minusculus Walker, 1869 in China for a long time (He, 2018; Yin & Liu, 1995). Gorochov (2017) considered this species is a synanthropic species and widely distributed in many tropical regions, such as Thailand, the Andaman Islands, Hawaii, Vietnam, Cambodia, South China, continental India, Sri Lanka, South Iran and Oman., Published as part of Ma, Libin, Zheng, Yanna & Qiao, Min, 2021, Revision of Chinese crickets of the tribe Modicogryllini Otte & Alexander, 1983 with notes on relevant taxa (Orthoptera: Gryllidae; Gryllinae), pp. 227-252 in Zootaxa 4990 (2) on pages 240-242, DOI: 10.11646/zootaxa.4990.2.2, http://zenodo.org/record/5026190, {"references":["Chopard, L.
