Krisna furcata View in CoL sp. nov.

( Figs 3 View FIGURES 1 – 8 , 11 View FIGURES 9 – 16 , 20 View FIGURES 17 – 25 , 43–52 View FIGURES 43 – 52 )

Yellow brown to fuscous, forewing with gray stripe along anterior margin of 3 subapical cells.

Crown short, with rounded anterior margin between eyes, medially slightly longer than next to eyes, anterior margin with distinct rim as in K. strigicollis . Ocellus situated on front margin of crown next to corresponding eye, separated from eye by distance equal to ocellus diameter. Male eighth sternite with hind margin slightly concave.

Male genitalia: Ventral pygophore process forked at apex, without small teeth and spicules, apical area of longer fork with few longitudinal rugae. Connective T-shaped with anterior margin medially produced. Subgenital plate with basal stem short. Style very long, apophysis long and narrow, slightly curved dorsally at apex without thickening. Aedeagus elongate, gradually narrowed to apex, curved dorsally near apex; more or less of uniform width in caudal view; phallotreme subapical on ventral surface.

Measurements: Male 9.6mm long, 2.7mm wide across eyes, 3.0mm wide across hind margin of pronotum.

Material examined: Holotype ɗ, China: Yunnan Prov., Xishuangbanna, Mengla, 870 m, 1 May 1974, Zhou Yao and Yuan Feng ( NWAFU).

Distribution: China (Yunnan).

Remarks: This species resembles Krisna viridula Li & Wang externally but can be distinguished from the latter by its smaller size, by the basal projection of the ventral pygophore process being longer than half the length of pygophore process and by the aedeagal shaft being symmetrical at apex.

Etymology. The name of this species refers to the forked ventral pygofer process.
