Ochraceous, anterior margin of head fuscous. Forewing appendix without basal fuscous spot. Hind wings milky white.

Head with crown short, anterior margin slightly rimmed and rounded between eyes, medially slightly longer than next to eyes. 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 almost straight.

Male genitalia: Pygophore elongate, with many macrosetae posteriorly; ventral pygophore process in lateral view sinuate, with or without small tooth at midlength, with spicules in basal half of expansion and apical area with few longitudinal rugae. Style very long, apophysis long, narrow, slightly curved dorsally near apex with thickening not extending half width near apex. Aedeagal shaft stout and curved dorsally in lateral view, hind margin convex with short rugae at mid region, then narrowed to apex, with distinct ventral concavity, in caudal view, widened near midlength, then slightly narrowing towards apex; phallotreme apical on ventral surface.

Measurements: Male 8.7–10.0mm long, 2.2–2.3mm wide across eyes, 2.6–2.9mm wide across hind margin of pronotum. Female 9.9–11.6mm long, 2.4–2.5mm wide across eyes, 2.9–3.3mm wide across hind margin of pronotum.

Distribution: China (Guangxi, Henan, Hunan, Hubei, Guizhou, Jiangxi, Shaanxi, Hainan, Zhejiang, Xizang), Myanmar ( Burma).

Remarks: Krisna rufimarginata was described from Henan Province, China, based on one male specimen. Viraktamath (2006) described Krisna burmanica from Myanmar based on one male. Although the descriptions of these two taxa indicate that they differ slightly in the apical shape of the aedeagal shaft in lateral view, these differences appear to intergrade among and within populations based on the males from different localities examined here, and therefore do not seem sufficient to justify continued recognition of the latter taxon as a distinct species.
