Figure 1 View FIGURE 1
Description. Male. Body medium. Face almost smooth; fastigium verticis about 2 times as wide as scape; fastigium frontis separated from fastigium verticis by a very fine suture ( Fig. 1A View FIGURE 1 ). Ocelli indistinct ( Fig. 1A View FIGURE 1 ).
Anterior margin of pronotum faintly projecting in middle, posterior margin nearly straight ( Fig. 1B View FIGURE 1 ); lateral lobes longer than high, ventral margins widely arched ( Fig. 1C View FIGURE 1 ).
Fore coxae with 1 small spine; femora unarmed on ventral surface, tibiae ventrally with 4 pairs of spurs and 1 pair of apical spurs. Middle tibiae ventrally with 3 pairs of spurs and 1 pair of apical spurs; dorsal surface of middle tibiae with 1 internal spine. Hind femora with 5 internal and 3 external spines on ventral surface, the second spine obviously longer ( Fig. 1F View FIGURE 1 ); tibiae arched ( Fig. 1E View FIGURE 1 ), dorsal surface with 6 – 7 internal and 6 external spines and 1 pair of apical spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs.
Second and third abdominal tergites with two rows of stridulatory pegs ( Fig. 1G View FIGURE 1 ). Posterior margin of eighth abdominal tergite faintly projecting. Ninth abdominal tergite curved downward, behind middle area divided ( Fig. 1K View FIGURE 1 ), the lateral lobes terminating into a short spine, its apex faintly curved outward ( Fig. 1L View FIGURE 1 ). Subgenital plate transverse; posterior margin with bowl-shaped concavity, the lateral lobes terminating into a digitate lobe, gradually upcurved, its apex obtuse ( Fig. 1L View FIGURE 1 ).
Female. Unknown.
Coloration. Body yellow brown. Face with 1 longitudinal black stripe in middle. Genae with 1 longitudinal black stripe on each side. Front-clypeal sulcus black with 1 pair of black spots ( Fig. 1A View FIGURE 1 ). Fastigium verticis with narrow transverse black stripe. Internal margins of antennal sockets black ( Fig. 1A View FIGURE 1 ). Antennae with black ring on each segment. Dorsal surface of head with semicircular black stripe. Dorsal surface of body with narrow longitudinal black band. Pronotum with black margins, which widened at ventral margins of lateral lobes ( Fig. 1C View FIGURE 1 ). Fore and middle legs with apical areas of femora black. Basal and apical areas of all tibiae black. External surface of hind femora with larger black patterns ( Fig. 1D View FIGURE 1 ). Dorsal spines of hind tibiae black ( Fig. 1E View FIGURE 1 ).
Measurements (mm). Male: BL19.54, PL 3.68, HFL 9.98.
Material examined. Holotype: male, Diding, Jingxi , Guangxi, August 14, 2023, coll. by Qianwen Zhang and Zixiu He.
Distribution. Guangxi (Jingxi).
Discussion. The new species differs from other species of Apterolarnaca (Apterolarnaca) by the hind femora with stout ventral spines, especially the second spine about three times longer than other spines; the posterior concavity of male subgenital plate bowl-shaped, obviously wider than other species.
Etymology. The name of the new species refers to the second longer spine of hind femora.
