Figures 1–2, 3A–F
Male. Body medium. Face with scattered impressed dots (Fig. 1A). Ocelli distinct (Fig. 1A).
Fore coxae swollen with 1 small spine. Fore and middle femora ventrally unarmed; hind femora with 4 pairs of spines on ventral surface. Fore and middle tibiae ventrally with 4 pairs of spines and 1 pair of apical spurs; middle tibiae with 1 apico-internal spine on dorsal surface. Hind tibiae with 6–7 pairs of spines on dorsal surface, subapices with 1 pair of ventral spurs, apices with 1 dorsal and 2 ventral spurs on both sides.
Tegmina just reaching the posterior area of first abdominal tergite (Fig. 1C–D). Tegmina with two subcostal veins; radius forked near tip; media, cubitus anterior and cubitus posterior simple, undivided; with 3 anal veins, the last two with common base (Fig. 1C–D). Hind wings slightly longer than tegmina.
Abdominal stridulatory pegs very sparse, appearing as a single row on the second abdominal tergite, which a widely spaced, and as double rows parallelly distributed on third abdominal tergite (Fig. 1F). Eighth abdominal tergite prolonged (Fig. 1H). Ninth abdominal tergite narrowing and curved downward (Fig. 1F), posterior area slightly furrowed in midline, the both sides swollen and terminating into a long, slightly incurved, acute spine (Fig. 1I). Subgenital plate wider than long, ventral surface conically swollen in the middle area, posterior margin slightly concave in middle (Fig. 1J). Styli inserted at apico-lateral angles.
Female. Tegmina reaching the middle area of first abdominal tergite (Fig. 2D–E). Hind tibiae with 5 internal and 6–7 external spines on dorsal surface. Seventh abdominal sternite with apical area widened and posterior margin arched concave (Fig. 2I). Basal area of subgenital plate membranous with 1 pair of copulatory depressions in the middle area; lateral margins after middle are converging, posterior margin narrowly rounded (Fig. 2J). Ovipositor strongly upcurved, apices narrowly subacute (Fig. 2K).
Measurements (mm). BL: ♂ 22.5–24.2, ♀ 22.5; PL: ♂ 5.5–6.3, ♀ 5.6; TL: ♂ 4.8–5.2, ♀ 5.1; HFL: ♂ 13.2– 13.9, ♀ 13.8; OvL: 10.8.
Coloration. Body yellowish brown. Eyes black. Pronotum black with blackish margins, disc with an indistinctly yellowish brown midline (Figs. 1B, 2C). Abdominal tergite blackish brown. Tegmina brown.
Material examined. Holotype: male, Gulinjing, Maguan, Yunnan, June 28, 2021, coll. by Wei Bin, Xiaoyu Peng and Xun Bian. Paratypes: 2 males and 1 female, the other information as holotype.
Distribution. Yunnan (Maguan).
Discussion. The new subspecies differs from Neolarnaca vera nigrinotum Ingrisch, 2018 in: tegmina shorter than the length of pronotum; male subgenital plate wider than long, median concavity of posterior margin shallower.
Etymology. Dedicated to Miss Liying Guo as a recognition to her contributions to Chinese Gryllacrididae.
