Blastobasis glauconotata Adamski

Blastobasis glauconotata Adamski

DIAGNOSIS. Blastobasis glauconotata is most similar to B. chuka, but it differs from the latter by having a slightly narrower uncus, a wider inner surface of the acuminate process of the lower part of the valva, a narrower microtrichiate area of the valva, a shorter aedeagus, a broader anellus of the aedeagus, and female with a ductus bursae that is 2/3 the length of the ovipositor.

DESCRIPTION.

Head: Vertex and frontoclypeus with scales grayish brown tipped with pale grayish brown; labial palpus with outer surface of segments I and II grayish brown intermixed with few pale grayish brown scales to apical margin, segment III grayish brown; inner surface as above except, segment III darker; scape and flagellum of antenna pale grayish brown; male first flagellomere dilated, forming a notch between itself and flagellomeres 2–4; proboscis pale grayish brown.

Thorax: Tegula and mesonotum brown basally, grayish brown distally. Legs brown with a pale grayish brown band near middle of all segments and apices of all segments and tarsomeres. Forewing (Figure 46) length 6.8–9.1 mm (n = 23), grayish brown intermixed with a few pale grayish brown and brown scales or basal 1/3 pale grayish brown, distal 2/3 slightly darker; four small brown spots present; three spots within cell, one near middle and two on distal end near crossvein; one spot posterior to midcell spot on CuP; marginal spots dark gray or faint. Undersurface grayish brown. Hindwing pale grayish brown basally, gradually darkening to apex.

Abdomen: Male genitalia (Figure 14): Uncus broadly curved ventrally from a slightly widened base, apex rounded narrowly; gnathos narrow, dorsoposterior margin bidentate medially; dorsal strut present; vinculum wide; juxta bandlike; valva divided; costa of upper part produced into a setose, digitate process; lower part of valva moderately wide, subventral area reflexed to apicoventral margin; apicoventral margin slightly angular, produced into an inwardly curved process; process broad, inner surface flattened; proximal flange elongate, overlaid by dense microtrichiate membrane, narrowed distally, contiguous with digitate process; aedeagus and sclerite of aedeagus slightly curved slightly above midlength; anellus broadly rounded apically, bearing several conical setae. Female genitalia (Figure 31): Eighth tergum with a narrow, darkly pigmented streak along median longitudinal axis; ostium slightly posterior to seventh segment; membrane surrounding ostium microtrichiate; medioposterior margin of seventh sternum slightly emarginate medially; inception of ductus seminalis slightly anterior to ostium; ductus bursae about 2/3 length of ovipositor, with internal imbricate platelets on anterior half; corpus bursae slightly elongate; signum with a spine-like process arising from middle of a slightly elevated base.

ETYMOLOGY. The species epithet, glauconotata, is a compound word derived from the Latin, glauco, meaning gray, and nota, meaning spot, referring to the dark gray marginal spots on the distal third of the forewing.

DISTRIBUTION. Blastobasis glauconotata is known from habitats in the central and western highlands and in the central midaltitudes of Ngaia Forest at 1230 m.
