Figures 1–3 , 7C

Description. Body stout. Face ovoid, with impressed spots; fastigium verticis about 2.9 times as wide as scape ( Fig. 1A ). Ocelli indistinct. Eyes small.

Anterior margin of pronotum straight, posterior margin widely arched; lateral lobes longer than high, posterior margin oblique without humeral sinus, anterior angle roundly arched, posterior angle slightly projecting downwards, ventral margins undulated ( Fig. 1C ).

Fore coxae with one spine. Fore and middle unarmed on ventral surfaces; hind femora ventrally with 6–9 internal and 12 external spines, the external spines larger than the internal ones. Fore and middle tibiae with four pairs of spines and a pair of apical spurs on ventral surfaces; hind tibiae slightly curved with 5–6 internal and 6 external spines on dorsal surface, apices with 3 pairs of spurs.

Wings reaching the middle area of eighth abdominal tergite. Left tegmen ( Fig. 3A, C ): Radius forks about two thirds area into two branches, after short distance connect, then again divided; M+CuA1 and CuA2 fused in basal area; CuA1 arises before middle area from MA+CuA1 and fuses with CuA 2 in short distance, then separates again and fuses in subapical area with MP; cubitus posterior undivided, free throughout; with 5 anal veins. Right tegmen ( Fig. 3B, D ): Radius forks two branches in two thirds area of tegmen, the first branche forked again near tip; MA and MP+CuA1 forked in middle area, the first branch connects with RS and shortly after divided again, the second branch divides into MP and CuA1; CuA2 fuses in basal area with M+CuA1; CuP undivided, free throughout; with 5 anal veins.

Abdominal stridulatory pegs inconspicuous, only with some seta. Eighth abdominal tergite prolonged. Ninth abdominal tergite globular but short and strongly curved downwards, in apical area with medial furrow, the lateral margin with a pair of processes, which curved dorsad and slightly forward ( Fig. 1F, G ). Tenth abdominal tergite with 1 pair of tuberculate processes in the middle ( Fig. 1G ). Cerci slender, conical. Subgenital plate wider than long with basal margin arched concave, lateral margins convex and apical margin bilobate, posterior margin with one nearly V-shaped concavity ( Fig. 1G ). Styli inserted at the apical area of lateral lobes of subgenital plate.

Female. Unknown.

Coloration. Body brown, dorsum of head with 5 black spots, face with 5 pairs of black spots, of which 4 at antennal socket, 2 at clypeo-frontal suture, the other 4 at front area ( Fig. 1A–B ). Internal margins of scape and pedicel, and basal segments of flagellar black brown, the other segments of flagellum blackish. Pronotum pale brown with black band at posterior margin which extending to lateral lobes, disc with 2 pairs of blackish brown spots ( Fig. 1C–D ). All femora, basal area and distal area of fore and middle tibiae, and all spines on hind femora black ( Fig. 2 ). Tegmina brown transparent, apical area yellowish-whitish, veins little darker; hind wings transparent ( Fig. 2 ). All abdominal tergites and apices of hooks of male ninth abdominal tergite black.

Measurements (mm). BL: ♂ 25.3; PL: ♂ 5.3; TL: ♂ 13.9; HFL: ♂ 9.5.

Material examined. Holotype: male, Baishahe, Nanxi town, Hekou , Yunnan (103°57′38.6″E, 22°41′31.1″N), 17 June 2015, All. 275m, coll. by Zizhong Yang, D 20150617; DUIER.

Distribution. Yunnan (Hekou).

Discussion. The new species is very similar to Glolarnaca hainanica ( Li, Liu & Li, 2016) and Glolarnaca sinica ( Li, Liu & Li, 2016) , but differs from them in: front area and disc of pronotum with 4 black spots respectively; the concavity of male subgenital plate narrow and deep.

Etymology. To commemorate the 100th anniversary of the founding of Hebei University, the new species name refers to the great universal geographic map, Knuyu Wanguo Quantu, which is deposited in the Museum of Hebei University.
