Specimens examined.

Holotype: China • ♂; Yunnan Province, Baoshan City, Shidian County, Guojiafenbaobao ; 24.4611°N, 99.2853°E; 1210 m; 6.v.2025; Wei He leg. Paratype: China • ♀; same data as holotype . No additional non-type material examined.

Differential diagnosis.

This species belongs to the marmoricrura - group based on the genital lobe near half of the entire genitalia length, external paramere with a distinct outer process, and virga slender, slightly undulate, basally sclerotized, without lateral flanges, and unforked apically ( Hincks 1959). Within this group, it most closely resembles Cranopygia celebensis ( de Bormans, 1903) in male genital structure but differs in the shortened tegmina and concealed hindwings (vs. fully developed), penultimate sternite with an emarginate posterior margin (vs. rounded), and virga over three times as wide as that of C. celebensis ( Hincks 1959; Steinmann 1986).

Description.

Male. General appearance. Median-sized, whole body mostly setose (Fig. 10 A – C ). Body length 28 mm. Forceps symmetrical, length 5 mm.

Head. Head longer than broad; mostly dark brown, medially with one six-lobed pale area. Frontal and coronal sutures distinct. Eyes not prominent, about as long as genae. Antennae pale brown, with at least 29 segments; first antennal joint shorter than distance between antennal bases. Mouthparts brown to dark brown.

Thorax. Pronotum slightly longer than wide; anterior and lateral margins rounded; posteromedial margin distinctly emarginate, forming two posterolateral lobes. Median longitudinal furrow distinct. Surface mostly dark brown, with pale anteromedian and lateral areas. Visible part of mesonotum pale. Tegmina shortened, near 1.5 times as long as pronotum; mostly dark brown, with a big pale area on anterior half of dorsal surface. Scales of hindwings strongly reduced, with only extreme end visible. Legs slender, pale; second tarsomere near as wide as third (Fig. 8 D ).

Abdomen. Abdomen pale basally, other parts dark brown, gradually expanded to last tergite. Ultimate tergite broad, subquadrate; posteromedial extension rounded, with truncate posterior margin; weakly punctured; hairy laterally; median longitudinal sulcus present. Forceps dark brown, symmetrical, gently curved; bases strongly expanded; dorsal margin of inner surface with giant teeth basally and subapically, ventral margin fringed with small teeth and terminated by a giant subapical tooth; inner margin between subapical tooth and apex concaved. Penultimate sternite rounded, posterior margin emarginate.

Genitalia. Genitalia slender, pale brown (Fig. 11 A, B ). Paramere subtriangular basally. Genital lobes well developed; virga within genital lobe slender, apex widened and truncate; basal vesicle sclerotized, short, thin. External paramere slender, with mostly consistent width; incision of anterior margin deep, wide; inner process subconical, pointed apically; outer process shorter than inner process, obtuse.

Female. Body shape and coloration similar to male (Fig. 12 A – C ). Body length 29.6 mm. Second tarsomere near as wide as third (Fig. 12 D ). Forceps length 5.4 mm. Forceps contiguous, tapering, symmetrical; apically incurved; inner margins mostly straight and denticulate, basal teeth larger than subsequent ones.

Etymology.

The new species is named after Shidian County, the type locality.

Distribution.

The species is currently known only from Yunnan Province, China.
