Type material. CHINA, Yunnan Province: Holotype ♂, Wenfengsi (26.81°N, 100.18°E), Lijiang, 2650 m, 18.VII.2001, coll. HH Li and XP Wang, slide No. WYP05003. Paratype. 1 ♂, Nankang, Baoshan, 2009 m, 10.VIII.2014, coll. KJ Teng et al., slide No. RH16369.
Diagnosis. This species is similar to L. insulsalis (Lederer, 1863) in the male genitalia, but can be distinguished by the uncus with lanceolate, edge-serrulated process lateromedially, sacculus with a dorsal process, and median plate of the valva sublunate (Fig. 24). In L. insulsalis, the lateral process of the uncus is needle-shaped, the sacculus has two dorsal processes, and the weakly sclerotized median plate is subquadrate (Fig. 27).
Description. Adult (Fig. 8) wingspan 25.0–27.0 mm. Head white. Male labial palpus yellow mixed with reddish-fuscous and black; first segment about 1/6 length of second; second segment curved dorsad, appressed to vertex, hollowed out on inner side to receive long brush-like maxillary palpus; third segment black, tapering, about 1/7 length of second. Male maxillary palpus long brush-like, white. Male antenna yellow fuscous, mixed with black on dorsal surface, serrulate on ventral surface; scape extension apically reaching metathorax, reddish fuscous mixed with brownish yellow, basal half with long yellowish white hair-like scales ventrally, with long yellow hair-like scales apically. Thorax and tegula yellowish white mixed with black. Forewing with basal area dark gray, suffused with yellowish-white scales; median area pale pink mixed with yellow and black; distal area fuscous mixed with black, with white strips along veins, edged with black along both sides; antemedian line black, extending from basal 2/5 of costal margin obliquely inward to base of CuA 2, then inward to basal 1/4 of dorsum, edged with pale pink fascia along inner margin; postmedian line black, extending from distal 2/5 of costal margin slightly arched outward to CuA 1, then oblique inward to distal 1/3 of dorsum, edged with pale pink fascia along inner and outer margins; subterminal line dark gray, extending from distal 1/3 of costal margin outward to CuA 1, then oblique inward to distal 1/5 of dorsum, edged with yellow fascia along inner margin and pale pink fascia along outer margin; ill-defined, fuscous, rectangular patch from basal 1/4 of CuA 2 to middle of dorsum; cell with indistinct white hair-like scales running from base below lower margin of cell to middle of antemedian line; discal spot absent; discocellular spot represented by a black tuft of hair-like scales, brownish yellow on inner side, white on outer side; terminal line yellowish white. Hindwing concolorous with forewing; dark gray patch from below base of lower margin of cell to dorsum, with tuft medially, mixed white and black scales; yellow suffused with black fascia from base of Rs to dorsum, with fuscous tufts; black hair-like scales between M 1 and M 2, and between 1A and 2A longitudinally; cilia of both wings pale brownish yellow. Fore- and midlegs pale yellow, femora and tibiae suffused with fuscous scales, tarsi brownish yellow except each tarsomere yellow at apex; hindleg pale yellow.
Male genitalia (Fig. 24). Uncus sub-quadrate, covered with dense short hairs dorsally, with an elongate, lanceolate, edge-serrulated process lateromedially. Gnathos lateral arm widely, joined apically; distal process quadrate, trifurcate apically. Valva rhomboid, with long hairs, slightly narrowed at basal 1/3, concave terminally; sclerotized median plate sub-lunate, joined with apex of sacculus posteriorly; costa reaching apex of valva. Sacculus about 3/4 length of ventral margin of valva, basal 2/3 almost uniformly wide, distal 1/3 much narrow; dorsal process at middle, sub-triangular, trifurcate apically. Juxta vase-shaped; lateral lobes obliquely straight on outer margin, slightly sinuate on inner margin, pointed at apex. Phallus about 4/5 length of ventral margin of valva, curved at basal 2/5; cornutus short, spine-shaped.
Female unknown.
Distribution. China (Yunnan).
Etymology. The specific name is derived from the Latin furcellatus, referring to the dorsal process of the sacculus that is trifurcate apically.
