Figure 6
Description. Female. Body medium.
Head. Face ovoid; fastigium verticis about twice as wide as scape; fastigium frontis separated from fastigium verticis by a very fine suture (Fig. 6A). Ocelli indistinct.
Thorax. Anterior margin of pronotum faintly projecting in middle, posterior margin triangularly concave in middle (Fig. 6B); lateral lobes longer than high, anterior angle widely arched, posterior angle rounded, humeral sinus shallow (Fig. 6C). Fore coxae with 1 small spine. Fore and middle femora unarmed; hind femora ventrally with 9 internal and 10 external spines. Fore and middle tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces, middle tibiae with 1 internal spur on dorsal surface. Hind tibiae dorsally with 6 pairs of spines and 1 pair of apical spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs. Wings slightly surpassing the apex of abdomen.
Abdomen. Second and third abdominal tergites each with few minute stridulatory pegs (Fig. 6D). Lateral margins of seventh abdominal sternite faintly convex and then converging after middle area; ventral surface in basal half convex and following with a transverse groove; posterior margin subtriangularly projecting, apical margin rounded, the ventral surface inconspicuously raised (Fig. 6F). Subgenital plate longer than wide, base covered by the projection of seventh sternite in middle (Fig. 6E); lateral margins gradually converging, posterior margin with a small median concavity (Fig. 6E). Ovipositor falcate, in subbasal area strongly, afterwards regularly upcurved and with gradually converging margins; tip narrowing, subacute (Fig. 6G).
Male. Unknown.
Coloration. Body brownish. Clypeo-frontal suture with 2 pairs of black spots. Between antennal sockets with 2 pairs of small black spots. Internal margins of antennal sockets with a small black spot. Fastigium verticis with 3 black spots, dorsum of head with 1 narrow obliquely longitudinal band on each side. Eyes black. Pronotum light brown with 3 pairs of small black spots and 1 pair of large black bands (Fig. 6B). Apical areas of all femora black, basal and apical areas of tibiae with black rings, the apical area slightly lighter. Tegmina brown.
Measurements (mm). Female: BL 20.03, PL 4.45, TL 21.85, HFL 9.91, OvL 9.44.
Material examined. Holotype: female, Caiyanghe, Puer, Yunnan, June 30, 2024, coll. by Siyu Pang and Ting Luo.
Distribution. Yunnan (Puer).
Discussion. The new species differs from Glolarnaca nigrimacula Yang, Lu & Bian, 2021 in the coloration of body and the shape of female subgenital plate (Fig. 7F).
Etymology. The new species name derives from the shape of female subgenital plate without longitudinal carinae.
