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.
