Type material. Holotype ( Figs 1 , 33 ): male, “ Myanmar (Burma) [Kachin State] | 50 km E Putao | env. Nan Thi village | 950 m, 11–16. V. 1996 | leg. Murzin & Sinjaev [recte: Sinyaev] | Museum Witt” / “Slide | ZSM Arct. | 2019- 382♂ | A. Volynkin ” ( MWM / ZSM).

Diagnosis. The forewing length is 12.0 mm in the male holotype. Siccia kachina sp. n. is externally reminiscent of S. angusta sp. n. but distinguished by the broader forewing, the larger antemedial and medial costal spots, and the smaller and diffuse subapical costal spot. The male genital capsule of the new species is similar to S. angusta sp. n. but differs in the shorter uncus, the shorter vinculum, the proximally narrower valva with a less convex dorsal margin, the markedly shorter cucullus, the considerably longer and broader distal membranous lobe, the shorter sacculus with a larger and dorsally protruding distal saccular process, and the longer juxta. The phallus of S. kachina sp. n. is remarkably shorter and broader than in S. angusta sp. n. Compared to S. angusta sp. n., the vesica of the new species is substantially broader, has a considerably longer and broader ventral diverticulum bearing a cluster of spinulose scobination (it is covered with graniculi in the congener), the membranous medial diverticulum (it bears a cluster of spinulose scobination in S. angusta sp. n.), and the short, conical and membranous distal diverticulum, which is strongly elongate, utricular and granulose in S. angusta sp. n.

The female is unknown.

Distribution. Northern Myanmar (Kachin State).

Etymology. The specific epithet is derived from Kachin State of Myanmar, where the new species is found. The name is a noun in nominative singular in apposition to the generic name.
