Bocchoris trimaculalis ( Snellen, 1880) ( Figs 2B, 4B, 5B)

Aediodes trimaculalis Snellen, 1880:232–233 . TL: Indonesia, Sulawesi, Makassar.

Material examined. 1♂, INDIA, Andaman and Nicobar Islands, Great Nicobar Islands, Chingam Basti , 09-XI-2018, coll. K.C. Gopi and party; 1♂, INDIA, Andaman and Nicobar Islands, Great Nicobar Islands, Great Nicobar Biosphere Reserve, Bird watching Point , 14-XI-2018, coll. K.C. Gopi and Party.

Diagnosis. Wingspan 14–16 mm. Bocchoris trimaculalis can be distinguished from other congeners by the blackish ground colour of its wings, white tegulae, two white patches on each forewing (one each in the medial and postmedial areas), and one white patch on the medial area of the hindwing. In the male genitalia, the uncus is broad and rounded with a spinous apex, the harpe is sclerotized, the juxta is shield-shaped, the sacculus is broad at the basal third, the saccus is V-shaped, and the aedeagus is slender and lacks cornuti.

Distribution. India (Meghalaya, Assam, Great Nicobar Island—Present Study), Laos, Myanmar, Thailand, Malaysia, Indonesia ( Whitaker et al., 2017).

Remarks. Previous records of Bocchoris trimaculalis in India were confined to the northeastern states of Meghalaya and Assam. This study significantly expands the known distribution of this species within India by documenting its presence in the Great Nicobar Island for the first time. Representative individuals of this species were observed in traps placed in the primary forests of the Great Nicobar Islands.
