Type material. Holotype: male, Damingshan, Shanglin, Guangxi, July 17, 2021, coll. by Dongdong Yang and Jing Liu.
Diagnosis. The new species is close to Homogryllacris rufovaria Liu, 2007, but differs from the latter in: processes of male tenth abdominal tergite hook-shaped and its apices not crossed each other (Fig. 1G–I); the lateral lobes of male subgenital plate triangular, median concavity narrower and shallower than the latter (Fig. 1I).
Description. Male. Body medium. Fastigium verticis wider than scape. Face with scattered impressed dots (Fig. 1A). Eyes long ovoid, ocelli indistinct.
Anterior margin of pronotum slightly projecting, posterior margin nearly straight (Fig. 1B), lateral lobes longer than high with V-shaped furrow, posterior angle arched (Fig. 1C).
Wings developed well, slightly surpassing apex of abdomen and reaching the middle of hind tibiae (Fig. 2A–B). Tegmina (Fig. 2C–D): radius with RS branching little before middle of tegmen, R forked near tip; media arises from radius behind basal third and shortly after divides into two branches, MA and MP; cubitus anterior and cubitus posterior undivided, free throughout; with 3 anal veins.
Fore coxae with 1 small spine. Fore and middle tibiae with 4 pairs of long spurs and a pair of short apical spurs on ventral surfaces separately; middle tibiae dorsally with an internal apical spine. Femora of right hind leg with 6 internal and 8 external spines on ventral surface; tibiae with 5 pairs of dorsal spines, 1 pair of dorsal apical spurs, 2 pairs of ventral apical spurs, and 1 pair of ventral subapical spurs.
Abdominal tergites two and three each with two rows of minute stridulatory pegs (Fig. 1D). Ninth abdominal tergite narrowing, trapezoidal in dorsal view (Fig. 1E). Tenth abdominal tergite short with 1 pair of hooks, its basal half stout and apical half terminating into a sharp spine pointing dorso-forward, the processes of both sides not crossed (Fig. 1G–I). Subgenital plate longer than wide, apical area forming two acute angular lobes, triangularly excised in between (Fig. 1I). Styli robust located on both sides of the subapical area of subgenital plate.
Female. Unknown.
Coloration. Body yellowish green with purplish red spots when alive, but color fading when deposited in absolute ethyl alcohol. Margins of antennal sockets black; bases and apices of scape and bases of pedicel, with black rings; basal flagellar segments blackish (Fig. 1A). Fastigium verticis with a black transverse spot. Pronotum with purplish red median band which widened at anterior and posterior margins (Fig. 1B). All legs with reddish spots. Tegmina semitransparent yellow; veins purplish red (Fig. 2C–D). Dorsal surface of abdomen purplish red (Fig. 1E). Apices of processes of male tenth abdominal tergite black (Fig. 1H).
Measurements (mm). Male: BL 23.3, PL 5.9, TL 18.6, HFL 12.7.
Distribution. China (Guangxi).
Etymology. The new species name is derived from Latin word “ ham ” referring to the shape of hooks of male tenth abdominal tergite.
