Description.

Head short with vertical pale and dark bands at posterior margin (Fig. 1K, L View Figure 1 ). Ocelli dorsal field with dark horizontal band (Figs 2J View Figure 2 , 3A View Figure 3 ). Pronotum dark brown, more or less varied fulvous, with black inferior margin (Fig. 5A, B View Figure 5 ). Elytra extending to the second last segment of abdominal tergite, a little rounded at apex; dorsal field shiny brown with a narrow yellowish band along external and apical margins; mirror reduced and somewhat broad. Wing long, extending to apex of abdomen (Fig. 9E, F View Figure 9 ). Legs rather short, widened, yellowish, mottled with brown and covered with abundant brown pubescence in which are mixed long bristles. Tibia rather thin, longer than femora, armed with seven internal spines (Fig. 6J, K View Figure 6 ). Abdomen pale brown with dark coloured. Ovipositor long, straight, with feebly flattened, acute apical valves, (Fig. 1K, L View Figure 1 ).

Male: LH 4.34 (mm), LP 4.06 (mm), LT 14 (mm), LF 12.6 (mm), LT 7.7 (mm), LT 07 (mm), TBL 21 (mm), Female: LH 2.5 (mm), LP 3.1 (mm), LT 11 (mm), LF 08 (mm), LT 7.4 (mm), LT 04 (mm), TBL 17 (mm).

Ecology.

This species was reported from Nagarparkar. This area is surrounded by rock and fine sand. It was observed that due to burrowing habits this species uprooted many valued plants. This species is here reported from Cymbopogon commutatus which are perennial grasses and mostly used for medicinal purposes in the locality.

Global distribution.

Australia, New Zealand, India, Pakistan ( Cigliano et al. 2020).

Remarks.

This species is commonly known as black field cricket. Its powerful legs are used for jumping. This species has numerous white strips on the abdomen which make it different from the other species. Zalitschek et al. (2012) reported that they are omnivores in nature. However, dietary requirements are similar but perform different functions depending upon the sex of the specimen: females take a protein-rich diet for the production of eggs while, male requires it for producing mating calls to attract females.
