Diagnosis. This species externally resembles L. tripartita , but differs by the structures of the male genitalia: the uncus is longer than the tegumen; the basal process of the costa is slightly expanded basally, with the apex slightly expanded and hook-like. The basal process of the costa is also similar to that of L. paranthyala , but distinctly longer. The differences between L. hamata and L. anthyalus are discussed under that species.

Description. Head. Dark-brown. Frons convex, brown. Male and female antennae filiform, reddish brown basally. Labial palpus brown, extending beyond frons, the outer side of the second segment with black patch centrally, the inner side greyish-white, apex of the second segment with thick and long scales. Thorax. Forewing length: male 13–15 mm. Thorax dark-brown. Legs dark-brown, with greyish-white circle patches; segments ends greyish-white; mid tibia with a pair of spurs, hind tibia with two pairs of spurs and with two greyish-white hairpencils at opposite side of spurs. Wing-pattern. Forewing dark-brown, tinged with purple; costal margin black; antemedial line double, light grey, following from basal one third of costa obliquely to basal one fourth of anal margin; medial line blackish-brown, deeply incurved between Sc and CuA2, straight and vertical from CuA2 to anal margin; reniform white, bordered with blackish-brown circle shadow outside; postmedial line double and wavy, yellowish-grey; space between postmedial and subterminal lines with series of semicircular black spots bordered with grey shadow anteriorly; terminal line black, interrupted by yellow dots on veins; fringes dark grey basally, yellowish-white terminally. Hindwing dark greyish-brown, its basal half hardly transparent, with the veins darkbrown; fringes same as forewing. Underside: both wings with basal half light greyish-brown, and terminal half darker greyish-brown; medial and postmedial lines wide and blackish-brown, postmedial line protruded outwards at costal margin terminal line light grey, slightly wavy; costal margin with small yellowish patches outwards of postmedial line and apex. Abdomen. Dark-brown, mixed with grey hairs. Male genitalia. Uncus longer than tegumen, snake-head shaped apically, with a small dish-like subterminal process. Gnathos absent. Tegumen triangular. Valva broad basally, pointed apically; sacculus with a series of long setae; basal process of costa strong, slightly expanded basally, about half length of valva, apex a little expanded and pointed. Juxta nearly rounded. Saccus as inverted triangle. Aedeagus short. Female genitalia. Apophyses anteriores short and slightly angled centrally, apophyses posteriores long and filiform. Both lateral lobes and post-ostial invagination absent. Ostium with two transversal folds posteriorly. Appendix bursae smaller than corpus bursae. Corpus bursae round, bearing a spinose and long strip shaped signum.

Distribution. China (Hainan).

Etymology. The specific name is derived from the Latin word hamatus, which means hook-like, and refers to the hook-like apex of the costa basal process of the male genitalia.

Remarks. This species was recorded by Chen (1999) from Hainan, China as L. tripartita ( Swinhoe, 1902) . In this study, we re-identified the specimens and found the male genitalia are distinctive from that of L. tripartita , so we regarded it as a new species. L. tripartita , therefore, is not distributed in China.
