Barsine garo Volynkin, 2018, Far Eastern Entomologist 358: 6, figs 3, 4, 22, 34 (type locality: "NE India, Assam, W Meghalaya, Garo Hills, Nokrek National Park, 25°40'N, 91°04'E, 1150 m").

Type material examined.

Holotype: male, "NE India, Assam, W Meghalaya, Garo Hills, Nokrek National Park, 25°40'N, 91°04'E, 1150 m, 2-13.VII 1997, leg. Afonin & Sinajev [recte: Sinyaev]", slide MWM 31769 Volynkin (MWM/ ZSM). Paratypes: 1 male, 6 females, the same data as in the holotype, slide MWM 31770 (female) Volynkin (MWM/ ZSM).

Diagnosis.

The forewing length is 10-10.5 mm in males and 10-11 mm in females. Ammathella garo is externally similar to A. midzhan but differs in the markedly larger size, the more reddish forewing ground color, and the pinkish hindwings. The male genital capsule of A. garo is distinguished from that of A. midzhan by the narrower tuba analis, the presence of a long conical medial process of the juxta, the somewhat smaller medial costal process, the smaller dorsal subapical costal process, and the more robust distal saccular process. The phallus of A. garo is longer (in proportion to the size of the genital capsule) than in A. midzhan . The phallus vesica of A. garo differs from that of A. midzhan in the narrower, conical subbasal diverticulum lacking a cluster of cornuti, and the longer and narrower cornuti of both clusters. In the female genitalia, A. garo differs from A. midzhan in the larger lateral ostial ligula, the narrower and markedly longer antrum, the weaker sclerotized appendix bursae, and the weaker spinulose scobination of the corpus bursae.

Distribution.

Known from northeastern India (Meghalaya) ( Volynkin 2018).
