Glolarnaca flata Luo, Zhang & Bian, 2024 View in CoL , Zootaxa, 5538: 552.

Holotype: Female, type locality: Caiyanghe, Puer , Yunnan.

The original description of this species was based on a female specimen. Herein, we provide the first description of male characteristics.

Description. Male. Body small. Head. Face ovoid; fastigium verticis broader than antennal scape. Eyes ovoid, slightly protruding forward and outward; ocelli indistinct, oval and small ( Fig. 1A–B View FIGURE 1 ). Thorax. Pronotum broad, anterior margin slightly protruding forward while posterior margin straight ( Fig. 1B–C View FIGURE 1 ). Lateral areas of second and third abdominal tergites each with 2 rows of stridulatory pegs. Tegmina and Wings. Wings narrow, extending beyond abdominal apex but not reaching apex of stretched hind tibia. Tegmen: R releases Rs behind the two-thirds base, both forked near apical area; MA releases MP behind the third base; CuA releases CuA1 and CuA2 behind the third base; MP and CuA1 shortly fuse near the middle; CuP unbranched, free throughout; with 4 anal veins. Hind wing slightly longer than tegmen. Abdomen. Ninth abdominal tergite globular, apical third narrow, divided into two lobes, their apico-lateral angles rounded, apical areas with a pair of elongate posterior processes, which curved dorso-proximad, narrowing, apices rounded ( Fig. 1D–F View FIGURE 1 ). Cerci long conical, slightly incurved, apices acute. Subgenital plate broad and short, basal margin slightly concave, lateral margins slightly convex, posterior margin with a nearly V-shaped notch, lateral lobes relatively broad. Styli cylindrical, apices rounded, inserted on lateral margins of apical area of subgenital plate ( Fig. 1F View FIGURE 1 ).

Female. Appearance is similar to that of male. Seventh abdominal sternite subrectangular, posterior margin with a small process in the middle. Base of subgenital plate slightly broad, other area narrowing, with several transverse folds, posterior margin slightly concave ( Fig. 1G View FIGURE 1 ). Ovipositor falcate, subbasal area stout, other area regularly upcurved and narrowing; tip subacute ( Fig. 1H View FIGURE 1 ).

Coloration. Body yellowish-brown. Fastigium verticis with 4 black spots, face with 8 black spots, occiput with 2 oblique black stripes, antenna brown ( Fig. 1A–C View FIGURE 1 ). Eyes black ( Fig. 1A View FIGURE 1 ). Disc of pronotum with 3 pairs of black spots ( Fig. 1B–C View FIGURE 1 ). Tegmina and hind wings transparent, veins dark brown. Apical areas of femora black, basal and apical areas of tibiae blackish-brown, spines and spurs on fore and middle tibiae brown; apices of spines and spurs on hind femur and hind tibia brown. Eighth and ninth of male abdomen with abdominal tergites black, apices of processes of ninth abdominal tergite black ( Fig. 1D–F View FIGURE 1 ).

Specimens examined. 1♂, Jiucheng, Yingjiang , Yunnan, 20 May, 2025, coll. Jie Su ; 1♀, Yongde, Lincang , Yunnan, 1 July, 2025, coll. Jie Su.

Measurements (mm). Body: ♂ 18.6, ♀ 23.0; pronotum: ♂ 4.0, ♀ 4.5; tegmen: ♂ 19.5, ♀ 18.3; hind femur: ♂ 8.1, ♀ 8.1; ovipositor: 7.3.

Discussion. The species was described by Luo et al. in 2024 based on a single female specimen. We examined a female specimen collected from Lincang, Yunnan, reveals identical external morphology to the original description, except for spots on pronotum. Based on this female specimen and a male collected from Yingjiang, Yunnan, we conclude that all examined specimens belong to Glolarnaca flata Luo, Zhang & Bian, 2024 , the difference in spots is attributed to variation among intraspecific populations.

Distribution. China ( Yunnan).
