Diagnosis.

This species is very similar to H. dissipatalis in appearance, but it can be distinguished in having the hindwing with the postmedial line distinctly excurved between M 2 and CuA 2 and closely accompanied by three pale yellow spots outside; the valva with its distal end nearly triangular and apically pointed; the phallus with three anteriorly connected cornuti; the corpus bursae with its posterior half cystiform and slightly narrower than the anterior half; and a transverse arciform signum. While in H. dissipatalis , the postmedial line of hindwing is slightly excurved between M 2 and CuA 2 and has no spot accompanied outside; the valva is very gradually distally narrowed and apically rounded; the phallus has a bunch of small, spine-like cornuti; the posterior third of corpus bursae is distinctly narrowed; and the arciform signum is longitudinal. In addition, male genitalia of H. coalita are similar to H. abstracta , especially in the shape of the cornutus, but H. coalita can be differentiated by the valva which has its distal end nearly triangular and apically pointed, the corpus bursae which is distinctly medially constricted, and the transverse arciform signum. In H. abstracta , the distal end of valva is nearly semicircular and apical end rounded, the corpus bursae is slightly posteriorly constricted, and arciform signum is longitudinal.

Description.

Adult (Fig. 3 C View Figure 3 ). Wingspan 22.0–28.0 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 fuscous. Forewing diffused fuscous at base one-third; costal fuscous, pale near postmedial line; orbicular stigma nearly round; discoidal stigma reniform; antemedial line closely accompanied by a 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, closely accompanied by three pale yellow spots intersected with outside broad band, then straight to discoidal stigma below and curved down to posterior margin. Cilia fuscous, with pale-yellow 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 yellowish-brown dorsally and terminally white mixed black at each segment, ventrally white.

Male genitalia (Fig. 4 E, F View Figure 4 ). Valva gradually narrowed distally, with distal end nearly triangular and apical end pointed; fibula slender. Phallus with three anteriorly connected cornuti, one short lamina, and two long bands (one curved, distally bilobed and the other relatively straight, longer, and distally pointed band).

Female genitalia (Fig. 4 K View Figure 4 ). Apophyses anteriores about two times length of apophyses posteriores. Ductus bursae approximately one-third length of corpus bursae. Corpus bursae with anterior half nearly elliptical, posterior half cystiform and weakly sclerotized, distinctly constricted medially; arciform signum transverse.

Etymology.

The specific name is derived from the Latin coalitus, meaning connective, in reference to the three connected cornuti.
