Type material.

Holotype: China · male, Sichuan Prov., Maoxian County, Wadi Township, Shahuzhai Village; 1938 m; 31°53.20'N, 103°28.62'E; 3 October 2019; Hao Xu, Zhi-Teng Chen, Lu Qiu leg (the holotype was reared from nymph by LQ).; SWU-B-CC-010020.

Other specimens examined.

1 male (an incompletely eclosed individual, unsuitable to be designated as a type specimen); SWU-B-CC-010021 · 1 female nymph, same collection data as holotype; SWU-B-CC-010022 .

Diagnosis.

This species is easily distinguished from its congeners by the reduced and stout tegmina and hind wings in male. In comparison with other species also possessing reduced tegmina and hind wings in males (e.g., E. everestiana reni and E. udenostyla Qiu, sp. nov.), this new species is obviously larger (24.7 mm without tegmina and wings in length), the tegmina with sparse macula only on distal half; while E. everestiana reni is small in size (18.0-18.5 mm without tegmina and hind wings in length) and with evenly distributed maculae on tegmina. E. udenostyla Qiu, sp. nov. (19.7 mm without tegmina and wings in length) is an almost unicolored black species with no styli in males.

Description.

Male holotype: Body short and broad (Fig. 5A, B View Figure 5 ). Measurements (mm): Overall length: 29.5; body length: 24.7; body width (tegmina not included): 13.4; pronotum length × width: 12.5 × 6.9; tegmina length × width: 22.5 × 9.3.

Coloration. Body yellowish brown. Pronotum brown, anterior margin yellow (Fig. 5C View Figure 5 ). Space between vertex to the ocelli black, face fulvous with blackish brown spots. Antennae yellowish brown, ante-clypeus yellow, hind-clypeus brown. Labial palpi and maxillary palpi yellowish brown (Fig. 5D View Figure 5 ). Tegmina and hind wings yellowish brown, maculae brown. Legs and abdomen brown.

Head: Interocular space narrow, obviously narrower than the distance between antennal sockets, and slightly narrower than the distance between ocelli. Ocelli large, ocellar ridge short, straight, covered with yellowish brown setae. Clypeus small (Fig. 5D View Figure 5 ). Pronotum: Widely transverse, the widest point near the middle, anterior yellowish margin wide, the boundary between the yellowish and the brownish portion fused. Surface with short pubescence (Fig. 5C View Figure 5 ). Tegmina and hind wings: Reduced and robust, exceeding the end of abdomen 4.4 mm. The apices of hind wings exceed tegmina obviously when at resting position (Fig. 5I View Figure 5 ). Tegmina translucent, yellowish brown, irregularly with several maculae apically, shoulders of tegmina wide, margins rounded. Wings translucent, light yellowish brown, almost no maculae. Legs: Slender, front femur type C1, arolia large, tarsal claws simple and symmetrical. Abdomen: Supra-anal plate transversely broad, convex in the middle, cerci short (Fig. 5E View Figure 5 ). Subgenital plate slightly asymmetrical, right portion larger than left, styli short (Fig. 5F View Figure 5 ). Genitalia: Well sclerotized (Fig. 5G, H View Figure 5 ). L1 slender, anteriorly prominently protruded, with a long protuberance on the left side and two well-developed protrusions on the posterior margin, L2 more developed on the right side, L3 curved, with a more rounded curvature, processa distale (pda) and processa apicale (paa) well developed, long and sturdy. Right phallomere relatively larger, R2 divided into two chunks, outer chunk larger than the inner one.

Female and ootheca: Unknown.

Nymph: Similar to the male in color, yellowish brown.

Natural history.

This new species is distributed in the Heishui River Basin (Maoxian County to Heishui County). Nymphs of this new species live beneath the withered grass at the edge of a soil slope (Hao Xu, Lu Qiu, pers. obs.; Fig. 5K, L View Figure 5 ).

Etymology.

The species epithet is from the Latin reductus indicating its reduced tegmina and wings.
