Redescription.
Adult (Fig. 3 A). Wingspan 22.0–32.0 mm, forewing length 10.0–16.0 mm. Frons brown. Vertex brown anteriorly, yellowish white posteriorly. Antenna yellowish brown; ventral cilia about one-third length of flagellomeres diameter in male. Maxillary palpus black-brown, white at base. Patagium brown. Tegula light brown, yellowish white distally. Forewing and hindwing pale yellow, with fuscous stigmas, lines, and broad bands along outer margin. Forewing diffused fuscous at base, proximal two-thirds of costal and broad band along outer margin fuscous; orbicular stigma a patch; discoidal stigma quadrilateral, extended to costal; antemedial line closely accompanied by a fuscous 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; postmedial line slightly excurved between M 2 and CuA 2, then straight to discoidal stigma below and nearly straight downward, connected to outside broad band at CuA 2 and merged into outside broad band after CuP. Cilia brown, mixed with some white. Legs off-white, front coax and femur light brown; middle tibia brown; hind tibia with outer distal spurs half length of inner distal spurs. Abdomen dorsally yellowish brown and terminally diffused white and black at each segment, white ventrally.
Male genitalia (Fig. 4 A, B). Valva very gradually narrowed distally, distal end rounded; fibula short and small. Phallus with a bunch of small, spine-like cornuti arranged in a curve.
Female genitalia (Fig. 4 I). Apophyses anteriores about two times length of apophyses posteriores. Ductus bursae approximately one-quarter length of corpus bursae. Corpus bursae elliptical anteriorly, posterior third distinctly narrowed and weakly sclerotized; arciform signum longitudinal, with a hill-like protrusion medially.
Distribution.
China (Chongqing, Hunan, Yunnan, Guangxi, Guangdong, Hainan, Fujian, Taiwan), Indonesia, India, Sri Lanka, Japan (Hampson 1896; Caradja 1925; Kirti and Rose 1987).
Remarks.
Hemopsis nr. dissipatalis of Matsui et al. (2022) is quite different from H. dissipatalis (Lederer, 1863) described and illustrated by Kirti and Rose (1987). According to Matsui et al. (2022), H. dissipatalis identified in Japan, is characterized by the conical uncus and the corpus bursae having a transverse signum. However, according to the description and illustration by Kirti and Rose (1987), the uncus of Hemopsis species is reduced and the female genitalia of H. dissipatalis has a longitudinal signum. In addition, we found H. nr. dissipatalis illustrated by Matsui et al. (2022; supplementary file S 1) has a spindle-shaped valva; the fibula is well developed, with its tip curved downward toward sacculus; and the phallus has claw-like, larger, leaf-like cornuti. However, in H. dissipatalis, the valva is tongue-shaped; the fibula is short and small, tip curved upward toward the costa; and the phallus has a bunch of small, spine-like cornuti. Therefore, we do not consider H. nr. dissipatalis of Matsui et al. (2022) to be a species of Hemopsis.
