Aeropedellus ganziensis Chen & Li sp. nov. ( Fig. 1 A–G , Fig. 2 A–F )

Holotype ♂, paratypes 5♀ 5♂ Ganzi, Sichuan, China. 2023. VII. 23. Coll. Hainan Chong.

Etymology. The specific epithet is named after Ganzi, the type locality.

Male. Body small ( Fig. 1 A ). Fastigium sharp in dorsal view, with long and distinct fastigial foveolve ( Fig. 1 B ). Frons slightly oblique in profile, frontal costa distinct and concave in median ocellus. Antennae long, 21 segments, nearly reached the posterior of pronotum, and slightly clubbed in terminal. Eyes oval; vertical diameter of eyes 1.2– 1.3 times that of transverse and 1.3–1.4 times subocular furrows. Median carina and both lateral carinae of pronotum distinct, lateral carinae curved in median; last transverse sulci cut median carina and lateral carinae deeply; the length of prozona 1.1 times metazoan; the maximum width of inner lateral carinae is 1.7 times minimum. The width of metasternal interspace is 1.5 times length, and nearly equal than metasternal lobes. Tegmina long, reached the base of epiproct and half of hind femur; the width of the median vein area is two times that of the cubital vein area ( Fig. 1 C ). Hind femur with stridulatory pegs in inner lower carinula, both upper and lower lateral genicular lobes round ( Fig. 1 D ). The length of hind femur 4.3 times as long as wide. Hind tibia with 11 spines on inner side and outer side, external apical spine absent. Tympanal organ develop, broad-ovate. Epiproct with longitudinal groove in middle, and with denticles on the middle of both sides. Cerci long, flattened, broadly ovate in lateral view, tip obtusely rounded. Subgenital plate short conical. Arolium between claws small, not reached the median of claws. Epiphallus inverted trapezoid; bridge bend up slightly; ancorae angular, curving inwards, with sharp tips; anterior projections angular, on higher than ancorae in dorsal and ventral views; lateral plates incline outwards; posterior projections extending outwards, small; lophi large, divide in two parts ( Fig. 2. A–C ). In phallic complex, length of the apical valves of penis nearly equal than cingulum valves; apodemes short than basal valves of penis, and slightly sharp at apice ( Fig. 2 D–E ).

Female. Body larger than male ( Fig. 1 E ), antennae short and stout, the length of median segment equal width, not reaching posterior margin of pronotum. The maximum of inner lateral carinae in pronotum is 1.9–2.0 times minimum ( Fig. 1 F ). Tegmina short, reaching end of 2nd abdominal tergite ( Fig. 1 G ). The width of metasternal interspace is 2 times length. Ovipositor valve terminally hooked; the lower margin with a row of small teeth.

Coloration. Body brown or green. Lateral carinae of pronotum with two black strips. Hind femur brown or green, with one black spot at medial base; terminal black. Hind tibia yellow, black slightly in terminal, apically of spines black.

Measurement (in mm): Length of body: ♂ 11.88–13.3, ♀ 14.83–18.75. Length of pronotum: ♂ 2.98–3.34, ♀ 3.57–4.12. Length of tegmina: ♂ 5.22–6.93, ♀ 4.17–5.88. Length of hind femur: ♂ 7.78–8.75, ♀ 9.16–10.63.

Diagnosis. The new species is similar to Aeropedellus changtunensis Yin, 1984 . The major differences are listed in Table 1 .
