Diagnosis.

This species is similar to H. angustalis in appearance, but it can be distinguished by its wings which have relatively larger stigmas, and the centrally lighter brown discoidal stigma; postmedial lines are smooth and somewhat thinner; the male lack a black anal tuft; the phallus has three anteriorly connected cornuti, one short and laminar and two long bands (one curved and distally bilobed and the other relatively straight, longer and distally pointed). In H. angustalis , stigmas are relatively smaller, and the discoidal stigma is uniformly fuscous; postmedial lines are somewhat punctated and thicker; the male has a black anal tuft; the phallus has three cornuti, with one small and spine-like and two long bands (one curved and the other relatively straight, longer and distally pointed) ( Kirti and Rose 1987: fig. 6).

Description.

Adult (Fig. 3 B View Figure 3 ). Wingspan 23.0–27.0 mm, forewing length 12.0–14.0 mm. Frons brown. Vertex yellowish brown. Antenna yellowish brown, ventral cilia about one-quarter length of flagellomeres diameter in male. Maxillary palpus brown, white at base. Patagium yellowish brown. Tegula light brown, distally yellowish white. Forewing and hindwing pale yellow, with stigmas, lines, and broad bands along outer margin brown. Forewing diffused brown at base and proximal half of costal; orbicular stigma nearly round, sometimes light centrally; discoidal stigma reniform, centrally light; antemedial line closely accompanied by a brown square spot below orbicular stigma; postmedial line distinctly excurved and merged with outside broad band between M 2 and CuA 2. Hindwing with discoidal stigma reniform, centrally pale yellow; postmedial line distinctly excurved between M 2 and CuA 2, then incurved to discoidal stigma below and curved down to posterior margin, well separated from outer broad band; outer broad band narrowed at middle. Cilia pale yellow, with brown basal line. Legs off-white; front coax and femur light brown; tibia distally brown; hind tibia with outer distal spurs two-thirds length of inner distal spurs. Abdomen dorsally yellowish brown and terminally white at each segment; ventrally white.

Male genitalia (Fig. 4 C, D View Figure 4 ). Valva very gradually narrowed distally, distal end rounded. Fibula comparatively well developed, with tip sharp. Phallus with three anteriorly connected cornuti: one short lamina and two long bands (one curved and distally bilobed and the other relatively straight, longer, and distally pointed).

Female genitalia (Fig. 4 J View Figure 4 ). Apophyses anteriores about 1 ½ times length of apophyses posteriores. Ductus bursae approximately one-third length of corpus bursae. Corpus bursae elliptical anteriorly, posterior third slightly narrowed and weakly sclerotized; arciform signum longitudinal.

Etymology.

The specific name is derived from the Latin abstractus, meaning separated, in reference to the postmedial line of the hindwing well separated from the outer broad band.
