Diagnosis: The new species Spatalina rimbiensis Irungbam &Schintlmeister , sp. nov. resembles to S. ferruginosa (Moore, 1879) ( Fig. 8 ) morphologically but can be distinguished by forewing ground color dark greyish brown S. rimbiensis Irungbam & Schintlmeister , sp. nov. which is light fuliginous-brown in S. ferruginosa . Forewing costa displays several blackish dots and a larger blackish apical blotch in S. rimbiensis Irungbam & Schintlmeister , sp. nov. which is absent in S. ferruginosa . The male genitalia are distinguished by shape of the uncus arms which are long and pointed in S. rimbiensis Irungbam & Schintlmeister , sp. nov. whereas very short and broader in S. ferruginosa ( Fig. 35 ) (in S. umbrosa (Leech, 1898) , uncus is Y-shaped with long uncus arms, while socii are longer and finger-like). The phallus of S. rimbiensis Irungbam & Schintlmeister , sp. nov. has a short and slightly curved and tapered tip whereas S. ferruginosa have a longer and blunt tip. Female S. rimbiensis Irungbam & Schintlmeister , sp. nov. genitalia display robust, rectangular-shaped antrums which are larger than those in known females of other congeners.

Description ( Figs. 5, 6, 7 ): Forewing length 19–21 mm in males and 24–26 mm in females. Male antennae bipectinated with short rami, those of the females are filiform. Forewing shape with rounded margin and apex, less elongated; ground color dark greyish brown; costa displays several blackish dots; and a larger blackish apical blotch. Veins of forewings tinged inconspicuous yellowish-brown. Hindwings are dark brown. Sexual dimorphism is limited, but the females are larger than the males. Male genitalia ( Figs. 32, 33 ). Uncus with long arms. Socii reduced in size and appear as a basal projection of the uncus. Valva bears a large basal projection, which is the largest in the entire genus; Valva apex rounded. Phallus short, curved and tapered at tip. Cornuti missing. 8th sternite deeply notched at their posterior margins. 8 th tergite with a pair of semispherical large projections. Female genitalia ( Figure 34 ). Apophyses anteriores slightly longer than apophyses posteriores. Antrum robust and rectangularly shaped, larger than in the known females of the other congeners. Ductus bursae slender and long; corpus bursae saccate.

Etymology: The species name is derived from the type locality of the holotype (Sikkim, Rimbi).

Distribution: India: Sikkim, Manipur. Elsewhere. Nepal.
