Apterolarnaca (Apterolarnaca) huanglianensis Bian & Lu, 2021 RỀXOidzfiễ

Figures 1–2

Description. Female (new description). Fore coxae with 1 spine. Fore and middle femora unarmed on ventral surfaces, hind femora with 9 internal and 8 external spines on ventral surface. Fore and middle tibiae with 5 pairs of ventral spurs, including 1 pair of apical ones; hind tibiae with 5 pairs of dorsal spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.

Second and third abdominal tergites each with two rows of stridulatory pegs (Fig. 2D). Subgenital plate slightly shorter than wide, the lateral margins obviously narrowing from basal to apical area, posterior margin nearly straight, the apico-lateral angles rounded (Fig. 2G). Ovipositor short and strongly curved upwards, with dorsal and ventral margins smooth, its apices obtuse (Fig. 2E); with a pair of digitate sclerites at base of ventral valvulae, which projecting outwards (Fig. 2G).

The coloration is same as the Bian et al. ’s (2021) description.

Material examined. 1 male and 1 female, Banggang, Menghai, Yunnan, August 25, 2019, coll. by Xun Bian. Measurements (mm). Female: BL 20.6, PL 4 . 0, HFL 11 . 4, OvL 6 .0.

Distribution. Yunnan (Lvchun, Menghai).

Discussion. The species is similar to Apterolarnaca (Bianigryllacris) bilobus (Guo & Shi, 2012) in ventral valvulae with a pair of digitate sclerites at base, but differs from the latter by: the posterior margin of female subgenital plate almost straight with smaller sclerites at base of ventral valvulae (Fig. 2C). While Apterolarnaca (Bianigryllacris) bilobus (Guo & Shi, 2012) has female subgenital plate with rounded posterior margin (Bian et al., 2014: Fig. 1L).
