Hemopsis Kirti & Rose, 1987

Hemopsis Kirti & Rose, 1987: 379. Type species: Botys dissipatalis Lederer, 1863, by original designation.

Diagnosis.

This genus is externally similar to Mecyna Doubleday, 1849 in appearance, but it can be distinguished by having the uncus reduced to a flat arch and by the long, balloon-shaped corpus bursae with a well-sclerotized arciform signum, while in Mecyna , the uncus is conical, and the corpus bursae is oval and has a longitudinal banded signum composed of granules. In addition, Hemopsis is very similar to Ategumia in external adult morphology and genitalia characteristics, but it can be distinguished by the forewing having the postmedial line excurved and merged with the outside broad band between wing veins M 2 and CuA 2; in Ategumia , the postmedial line of the forewing is slightly excurved and intersects with, or is separated from, the outside broad band between M 2 and CuA 2.

Redescription.

Adult. Body yellowish brown; wings faintly yellow with brown or fuscous markings. Frons rounded. Antenna filiform; male with short cilia ventrally. Labial palpus obliquely upturned, with basal two-thirds white, brown distally; the third joint short, projecting forward (Fig. 2 A View Figure 2 ). Maxillary palpus filiform. Forewing and hindwing with broad brown band along outer margin. Forewing with postmedial line from proximal two-thirds of costa and excurved between M 2 and CuA 2, then incurved to discoidal stigma below and sinuous to inner margin; cell somewhat less than half length of wing; R from cell at three-fourths above; R S 1 very close to R S 2 + S 3; R S 2 anastomosed with R S 3 about three-fifths beyond cell; R S 4 slowly curved and close to R S 3 + S 4 at base; M 2, M 3 and CuA 1 from posterior angle of cell and uniformly spaced at the base; CuA 2 from cell at three-quarters below. Hindwing with outer margin slightly protruded at Rs; cell less than one-third length of wing; discocellulars slightly incurved; Rs with one-quarter length anastomosed with Sc + R at base; M 2, M 3 and CuA 1 from posterior angle of cell; CuA 1 curved and approximated to M 3 at base; CuA 2 from cell at two-thirds below (Fig. 2 B View Figure 2 ). Legs long and slender; middle tibia with inner spur about twice length of outer spur; hind tibia with outer proximal spurs one-third length of inner proximal spurs.

Male genitalia. Uncus reduced to a flat arch; gnathos absent; valva tongue-shaped, bearing dense, long setae. Costa well sclerotized, inflated near base. Sacculus broad, protruded to base of fibula. Fibula hook-shaped, directed toward sacculus and distally curved toward costa. Saccus developed, triangular, with rounded end. Juxta U-shaped and sclerotized. Phallus cylindrical, with multiple cornuti.

Female genitalia. Papillae anales densely setose. Antrum slightly sclerotized. Ductus bursae marked with well-developed and sclerotized colliculum. Ductus bursae shorter than corpus bursae. Corpus bursae long balloon-shaped, with a well-sclerotized, arciform signum.

Distribution.

China, India, Indonesia, Sri Lanka, Japan ( Hampson 1896; Caradja 1925; Kirti and Rose 1987).

Remarks.

Although Ategumia is very similar to Hemopsis in external adult morphology and genitalia characteristics, we found they can be distinguished by the pattern of postmedial line of forewing. Moreover, they were well separated from each other in ML tree based on DNA barcodes.
