Glaucotunica n. gen.

Type species: Glaucotunica tamila n. sp., by monotypy.

Diagnosis

This genus is superficially similar to Anchimacheta but differs from the latter in having the rather greyish forewings. Overall structures of the male genitalia of Glaucotunica are convergent to those of Anchimacheta , but the gnathal arms are discontinuous medially only in Glaucotunica .

Description

Head with piliform scales on vertex; maxillary palpus short (1 segment); proboscis naked. Foreleg epiphysis at the middle. Hind tibia hairy ventrally. No apparent patch or patches of raised scales on the forewings. Forewing venation with Sc reaching costal margin near 1/2; R arising from near basal 3/5 of anterior margin of discal cell; Rs 1 arising from anterior end of accessory cell, slightly sinuous; Rs 2 arising from anterodistal end of accessory cell; Rs3 equidistant between Rs 2 and Rs 4; Rs 4 arising from posterodistal end of accessory cell, directed to apex; M 1 and M 2 nearly parallel in basal 4/5, slightly divergent in distal 1/5; M 2 and M 3 gradually divergent; CuA 1 slightly approximate to CuA 2 at basal 1/3; CuA 2 slightly sinuous; CuP convergent to 1A + 2A at distal 1/5; 1A + 2A sinuous. Hind wing venation with Sc + R 1 extending to costal margin near 3/5; Rs nearly parallel to M 1; anterior margin of discal cell slightly atrophied along basal 2/3; M 1 directed slightly below apex; M 2 closer to M 1 than to M 3 basally; M 2 and M 3 nearly parallel; M-stem 2/5 as long as anterior margin of discal cell; CuA 1 nearly straight; CuA 2 broadly arched, convergent to CuP; CuP as fold; 1A + 2A arched at distal 1/3, approaching to CuP fold in basal 2/3. Hair pencils absent on hind wings. The male genitalia with gnathos discontinuous medially; cornuti absent within phallus.

Etymology

The generic name is derived from two Latin roots, ‘ glaucus ’ and ‘ tunica ’, meaning ‘grey’ and ‘garment’ respectively, and refers to the grey forewings of the type species. The gender is feminine.
