( Figs 7 , 17 )

Type material. CHINA: Holotype ♂, Basianshan National Forest Recreation Area (Mt. Baxian) (24.15°N, 121.01°E), Heping District , Taichung City, Taiwan , 800–900 m, 16.VIII.2006, coll. Houhun Li and Xicui Du, slide No. WYP06018 ( NSYSU) .

Diagnosis. This new species is characterized by the lateral lobe of the juxta being a long hooked spine. It is similar to T. cornutitrifurca sp. nov., and the differences between them are stated under the proceeding species.

Description. Adult ( Fig. 7 ) wingspan 27.0–28.0 mm. Head white, mixed with black and greyish green. Male labial palpus with first segment greyish green, mixed with black, about 1/3 length of second; second segment reaching vertex apically, white, basal 1/3 and distal half black on outer side, with long white hair-like scales on inner side, ventral surface with long black-tipped grey hair-like scales on distal 1/3; third segment black, white basally and apically, with long blackish grey hair-like scales on ventral surface, about 1/3 length of second. Male maxillary palpus compressed and short; white, mixed with black apically. Male antenna with scape expanded, black on ventral surface, white on dorsal surface; flagellum with ventral surface yellowish fuscous, bearing short greyish white cilia slightly longer than diameter of antenna, dorsal surface white, with black annulations. Thorax and tegula white, with reddish fuscous and black scales on distal half. Forewing with basal area greyish green, mixed with black along dorsum, white at proximal base; median area white, mixed with greyish green and black scales, with a greyish green rectangular mark at middle of costal margin; distal area reddish fuscous, with dense black scales anteriorly and medially, with a white ovate spot between M2 and CuA1 on termen; antemedian line black, wide, from middle of lower margin of cell slightly oblique outward to beyond basal 1/3 of 1A+2A, then almost vertical to basal 1/3 of dorsum; postmedian line wide, black, greyish green on anterior 1/6, serrate, extending from distal 1/3 of costal margin oblique outward to M3, then inward to CuP, finally vertical to distal 1/3 of dorsum; discal and discocellular spots each represented by fan-shaped black tuft, with white scales bordering outer side; cell with a small black tuft at middle on lower margin, its outer side bordering white scales; terminal line greyish white, evenly spaced with uniform reddish fuscous rectangular spots along its inner side, interrupted with greyish white on veins. Hindwing with basal 2/3 white, distal 1/3 grey; with black spot on distal 1/3 of CuA2 and distal 1/4 of 2A respectively. Cilia of both wings pale reddish fuscous, interrupted with black on extension of veins. Legs white on inner side; on outer side, fore leg with femur reddish fuscous mixed with white and greyish green, tibia white mixed with reddish fuscous, black basally and apically; mid and hind legs with femora white mixed with black and reddish fuscous, tibiae white mixed with greyish green, with white mixed with greyish green hairlike scales; tarsi with each tarsomere white at apex. Abdomen with ventral surface fuscous mixed with earthy yellow; dorsal surface with 1st to 3rd segments greyish white, with longitudinal yellowish fuscous spots on lateral margin, remaining segments fuscous mixed with earthy yellow.

Male genitalia ( Fig. 17 ). Uncus sub-rectangular, slightly widened medially; apex straight. Gnathos narrowly banded, arched backward medially, without seta. Valva rhomboid, with dense long hairs on distal 1/3; with a small sub-square process at base carrying sparse long hairs, with warts distally; terminal margin obtuse; costa reaching apex of valva, with a triangular process at middle, with an apical spine; sacculus reaching apex of ventral corner of valva, gradually narrowed from base to apex. Juxta rectangular; lateral lobes spine-shaped, curved backward, almost as long as uncus. Saccus broad triangular. Aedeagus straight, about 1.2 times length of valva; cornutus being a long spine about 1/7 length of aedeagus.

Female unknown.

Distribution. China ( Taiwan).

Etymology. The specific name is derived from the Latin longispinus, referring to the cornutus being a long spine.
