Figures 6–7

Description. Male. Body medium. Head and pronotum as other species of the genus. Fore coxae with 1 spine; femora with 1 short ventral spine on internal margin; tibiae with 1 internal and 2 external spines ventrally, apices with 1 pair of spines on ventral surface. Middle femora with 1 pair of apical spines on ventral surface; tibiae dorsally with 2 internal and 3 external spines, ventral surface with 1 internal and 3 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind femora with 1 short ventral spine on internal margin; tibiae dorsally with 19–21 internal spines, 19–20 external spines and 1 pair of small subapical spines; tibial apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 2–3 small spines and 1 apical spine on dorsal surface along the midline (Fig. 6F).

Posterior margin of tenth abdominal tergite concave. Epiproct with basal half of lateral margins convex and then terminating to apex, roughly triangular in dorsal view (Fig. 6H), dorsal surface faintly concave, the apical area with 1 small spine and followed by 1 large spine (Fig. 6H, I), ventral margins of the apical area of the triangle rectangularly prolonged with 1 pair of spines at apex (Fig. 6H); ventral surface of epiproct with 1 large process, which longer than wide, dorsal surface concave, the surrounding margins sclerotized, posterolateral angles swollen and then prolonged into a spine on each side, which faintly incurved inserted at the middle area between styli (Fig. 6K, L). Subgenital plate deformed, wider than long, lateral margins convex; styli stout at basal area, then terminating into a depressed spine, upcurved behind basal third area (Fig. 6J), apical areas sclerotized, apices acute, inserted on posterolateral area of the plate (Fig. 6K).

Female. Posterior margin of tenth abdominal tergite concave in middle (Fig. 7H). Epiproct longer than wide, lateral margins convex, dorsal surface concave with median furrow, the lateral sides of the furrow raised (Fig. 7H). Cerci slender, apices subacute. Subgenital plate wider than long, lateral margins convex, posterior margin arched concave with small angular projecting in middle (Fig. 7I). Ovipositor slightly shorter than hind femora, gradually upcurved behind basal area, apices acute; dorsal margins smooth, subapical area of ventral margins serrate (Fig. 7F).

Coloration. Body brown, terga with small black-brown spots, sterna yellowish brown.

Measurements (mm). BL: ♂ 19.69–23.50, ♀ 21.03–23.27; PL: ♂ 5.99–6.52, ♀ 6.33–7.30; FFL: ♂ 6.92–7.75, ♀ 7.42–7.80; MFL: ♂ 7.86–8.01, ♀ 7.56–8.03; HFL: ♂ 18.10–18.94, ♀ 18.61–19.32; HBL: ♂ 3.75–2.95, ♀ 2.97–3.90; OvL: 16.17–16.24.

Material examined. Holotype: male, Xiaohaoping, Tengchong, Yunnan, August 10, 2023, coll. by Siyu Pang and Ting Luo. Paratypes: 2 males and 5 females, the other information as holotype.

Distribution. Yunnan (Tengchong).

Discussion. The new species differs from Rhaphidophora equalispina sp. nov. by male epiproct roughly triangular in dorsal view, the apical area with 1 small spine and 1 large spine along the midline (Fig. 6H, I), ventral margins of the triangle with 1 pair of spines at apex (Fig. 6H), the sclerotized ventral process longer than wide with large apical spines (Fig. 6K, L); male subgenital plate with styli stout at basal area and then terminating into a depressed spine; posterior margin of female subgenital plate arched concave with small angular projecting in middle (Fig. 7I).

Etymology. The name of the new species refers to the male epiproct with 1 large spine and 1 smaller spine along the midline on dorsal surface; from Latin word “ dispar ” and “ spin ”.
