Nosophora albiguttalis Swinhoe, 1890 ( Figs 2K, 4H, 5H)

Nosophora albiguttalis Swinhoe, 1890:273 . TL: Burma (Mayanmar).

Material examined. 1♂, India, Andaman and Nicobar Islands, Great Nicobar Islands, Galathea 42.7 Km , 18-XII-2019, coll. B. Sumit Kumar Rao (Reg. No. ZSI /ANRC-T-10825) ; 1 spec., India, Andaman and Nicobar Islands, Great Nicobar Biosphere Reserve, Bird watching Point , 26-XII-2019, coll. B. Sumit Kumar Rao (Reg. No. ZSI / ANRC /T-10826) ; 1♂, India, Andaman and Nicobar Islands, North Andaman, Bahadur Tikrey , 08-I-2019, coll. B. Sumit Kumar Rao (Reg. No. ZSI / ANRC /T-17109) .

Diagnosis. Wingspan 34 mm. Nosophora albiguttalis closely resembles Nosophora conjunctalis Walker, 1866 in external appearance but can be readily distinguished by the presence of a white lunular-shaped patch at the end of the cell and the absence of discal spots on the hindwings. Further differentiation is evident in the male genitalia, where Nosophora albiguttalis exhibits a broad uncus with setae and a flat apical tip, a broad, nearly rectangular valva with a basally concave ventral margin, a broad juxta narrowed apically with a U-shaped saccus, and a short, stout phallus equipped with three distinct sets of cornuti.

Distribution. Myanmar, China ( Hongkong), India (Assam, Haryana, Maharashtra, Manipur, Meghalaya, Nagaland, Tripura, West Bengal, Andaman and Nicobar Islands-Present Study), North Vietnam ( Caradja & Meyrick, 1933; Kendrick, 2002; Mathew, 2006).

Remarks. Documented for the first time from the Andaman and Nicobar Islands. Representative individuals of this species were observed in traps placed in both primary forest’s margins and secondary forest margins.
