Uncobotyodes Kirti & Rose, 1990

Uncobotyodes Kirti & Rose, 1990: 119 . Type species: Botys patulalis Walker, 1866 , by original designation.

Diagnosis. This genus is externally similar to Botyodes in appearance, but it can be distinguished by the paler yellow wings, the elongated uncus that is longer than the total length of the tegumen, vinculum and saccus, the broad distal uncus that is about as wide as the tegumen, the valva with a fibula, and the posterior half of corpus bursae densely covered with small granules. In comparison, in Botyodes , the wing is yellow, the uncus is somewhat shorter than the total length of the tegumen, vinculum and saccus, the distal uncus is less broad and about a quarter of width of the tegumen, the fibula is absent, and the corpus bursae is smooth.

Generic characteristics. Adult. Body and wings yellow. Frons rounded. Antenna filiform, densely with short cilia ventrally. Labial palpi obliquely upturned; 3rd segment short and porrect, hidden with scales ( Fig. 1 ). Maxillary palpi dilated with scales at extremity. Forewing with cell somewhat less than half length of wing; discocellulars arcuately incurved; Rs 1 closely approximated to Rs 2 +s 3; Rs 2 anastomosed with Rs 3 approximately half length of Rs 3; Rs 4 close to Rs 2 +s 3 at base,M 2, M 3 and CuA 1 from posterior angle of the cell. Hindwing with length of cell somewhat more than one-third length of wing; discocellulars incurved and oblique; Rs with a quarter length anastomosed with Sc+R at base; M 2, M 3 and CuA 1 from posterior angle of the cell ( Fig. 2 ). Legs silvery white. Middle tibia with distal inner spur approximately three times the length of outer spur.

Male genitalia. Uncus elongated, narrowed basally, the strikingly distally broad and setose. Tuba analis shorter than uncus. Valva broad. Sacculus broad, sclerotized. Fibula spine-like, curved. Saccus broadly rounded. Juxta water drop-shaped. Phallus long and slender. Posterior phallus with cornutus composed of a bunch of spines on vesica.

Female genitalia. Apophyses much slender, apophyses anterioris longer than apophyses posterioris. Ductus bursae slender, broad and slightly sclerotized near antrum. Corpus bursae elliptical. Signa absent.

Distribution. China, Bhutan, India.

Remarks. In accordance with Kirti & Rose (1990), Uncobotyodes can be identified by features of the adult appearance and male genitalia, especially the uncus. The female genitalia characteristics of the genus is provided in the present study for the first time.
