Differential diagnosis.

This species belongs to the picta - group, characterized by a mucronate external paramere with a poorly developed outer process and an extremely long virga that is basally sclerotized, without lateral flanges, and unforked apically ( Hincks 1959). It resembles Cranopygia manipurensis Srivastava, 1975 in having tegmina shorter than the pronotum, a deeply notched penultimate sternite, and a virga with a medial knob ( Srivastava 1975), but differs by its genital lobes and virga being about twice as long. It is also similar to Cranopygia corymbifera Anisyutkin, 1997 ( Anisyutkin 1997), but can be distinguished by its tegmina twice as long as wide (vs. three times) and by the virga near four times as long as the genital lobe (vs. near twice).

Description.

Male. General appearance. Median-sized, whole body mostly setose (Fig. 6 A – C View Figure 6 ). Body length 26 mm. Forceps asymmetrical in shape, with same length 5.1 mm.

Head. Head longer than broad; mostly dark, with small pale spot near antero-inner margin of each eye. Frontal and coronal sutures obscure. Eyes not prominent, about as long as genae. Antennae brown, with at least 31 segments; first antennal joint shorter than distance between antennal bases. Mouthparts pale brown to dark brown.

Thorax. Pronotum slightly wider than long; anterior and lateral margins rounded; posteromedial margin weakly emarginate. Median longitudinal furrow distinct. Surface mostly dark brown, with pale lateral areas. Visible part of mesonotum dark brown. Tegmina strongly reduced, slightly shorter than pronotum; dark brown. Scales of hindwings pale absent. Legs slender, mostly pale, with basal half of tibia brown; second tarsomere narrower than third (Fig. 6 D View Figure 6 ).

Abdomen. Abdomen dark, gradually expanded to last tergite. Ultimate tergite broad, subquadrate; posteromedial extension rounded, with truncate posterior margin; weakly punctured; mostly hairy; median longitudinal sulcus obscure. Forceps dark brown, subcontiguous; asymmetrical, right branch more curved than left branch; bases strongly trigonal, with inner-dorsal ridge; conical apically; inner margin crenulate nearly throughout except apex. Penultimate sternite rounded, posterior margin deeply notched.

Genitalia. Genitalia slender, pale brown (Fig. 7 A, B View Figure 7 ). Paramere subtriangular basally. Genital lobes well developed; virga within genital lobe thin, extremely long, with a distinct nodule near midpoint, apex widened and truncate; basal vesicle sclerotized, thicker than virga. External paramere slender, inner margin convex, outer margin straight, with mostly consistent width; inner process pointed, with a small tooth near midpoint of its inner margin; outer process weakly developed, rounded.

Etymology.

The new species is named after Liuhuai Mountain, the type locality.

Distribution.

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