Figures 1–2 View FIGURE 1 View FIGURE 2 , 3A–F View FIGURE 3
Male. Body medium. Face with scattered impressed dots ( Fig. 1A View FIGURE 1 ). Ocelli distinct ( Fig. 1A View FIGURE 1 ).
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 View FIGURE 1 ). 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 View FIGURE 1 ). 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 View FIGURE 1 ). Eighth abdominal tergite prolonged ( Fig. 1H View FIGURE 1 ). Ninth abdominal tergite narrowing and curved downward ( Fig. 1F View FIGURE 1 ), posterior area slightly furrowed in midline, the both sides swollen and terminating into a long, slightly incurved, acute spine ( Fig. 1I View FIGURE 1 ). Subgenital plate wider than long, ventral surface conically swollen in the middle area, posterior margin slightly concave in middle ( Fig. 1J View FIGURE 1 ). Styli inserted at apico-lateral angles.
Female. Tegmina reaching the middle area of first abdominal tergite ( Fig. 2D–E View FIGURE 2 ). 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 View FIGURE 2 ). 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 View FIGURE 2 ). Ovipositor strongly upcurved, apices narrowly subacute ( Fig. 2K View FIGURE 2 ).
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 View FIGURE 1 , 2C View FIGURE 2 ). 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 .
