Diagnosis. L. trigonoprocessa has a more distinct longitudinal white band on the forewing and a more distinct transparent zone at the base of the hindwing than the previous two species. L. trigonoprocessa also resembles L. vittigera Walker, 1865 (Australia), but can be distinguished from that species in the male genitalia, the valva has a triangular process at the middle of the costa, which is absent in L. vittigera.
Description. Head. Frons convex, greyish-brown, mixed with grey hairs basally,. Male and female antennae filiform, brown. Labial palpus brown, extended beyond frons, the second segment with thick and long scales terminally. Thorax. Forewing length: male 13–16 mm, female 15–16 mm. Thorax greyish-brown; tegulae covered with brown scales; patagia longer than half of mesothorax, covered with blackish-brown scales. Legs brown, ends of segments grey; hind tibia with two pairs of spurs and with two hair-pencils at opposite side of spurs. Wing-pattern. Costal margin of forewing with longitudinal black band from base to apex, widest near postmedial line, bordered below by longitudinal white band from base to postmedial line, with several black spots basally; antemedial line black, double; medial line black; reniform obscure, ringed with black; postmedial line double, black, wavy; antemedial and medial lines visible only between longitudinal white band and anal margin, postmedial line visible below black band; a wavy black line between postmedial and greyish-white submarginal lines, outlined with greyish-white shadow anteriorly; terminal line black, interrupted on vein ends; fringes blackish-brown at ends of veins, greyish-brown between veins. Hindwing blackish-brown with basal half transparent, tinged with purple shining, veins black. Underside: forewing basal half greyish-white, terminal half greyish-brown, submarginal line slightly visible at apex; hindwing blackish-brown, transparent in basal half. Abdomen. Brown, segments ends greyishbrown. Male genitalia. Uncus long, beak-like apically. Gnathos absent. Valva wide, with basal process of costa long and narrow, covered with short hairs; costa with a triangular process at middle; sacculus with a series of long hairs. Juxta oval, concave posteriorly. Saccus inverted triangular. Aedeagus long, narrow, with small bulge at apical one fourth. Female genitalia. Ovipositor short and wide, with thick hairs. Apophyses posteriores longer than apophyses anteriores. Lateral lobes reduced, post-ostial invagination not clearly expressed, ostium surrounded with folds. Appendix bursae same size as corpus bursae, corpus bursae rounded, with a short spinose signum.
Material examined. Holotype: male, CHINA, Hainan: Jianfengling, Tianchi, 934 m, 14.XII.2007, coll. Li Jing (IZCAS). Paratypes: Hainan: 1 male, 2 females, Jianfengling, 8.VI.1973, coll. Chen Yixin; 1 female, Wanning, Xinglong, 52 m, 21–22.III.2008, coll. Wu Chunsheng (IZCAS).
Distribution. China (Hainan).
Etymology. The specific name is derived from the Latin prefix trigono-, which means triangular, and processus, which means process. This refers to the triangular process at the middle of the costa of the male genitalia. Remarks. The post-ostial invagination of the female genitalia of this species is not distinct, but since it has the similar wing patterns as the previous species, we placed it in the species group D for the moment.
