(Figs 7, 20)
Type material. CHINA, Guangxi: Holotype ♂, Shaoping Farm, Pingxiang, 280 m, 28.V.2012, leg. XF Yang, slide No. GW 12245.
Diagnosis. The new species is similar to S. spinicornuta sp. nov., but it can be distinguished in the male genitalia by the cucullus smoothly obtuse on the dorsal margin, the V-shaped juxta extending outward posterolaterally, and the cornutus consisting of five long spines joined at base. In S. spinicornuta sp. nov., the cucullus is obtusely convex at distal 1/3 on the dorsal margin, the juxta is semi-rounded, and the cornutus consists of three strong spines in the male genitalia.
Description. Adult (Fig. 7). Wingspan 10.5 mm. Head with frons and vertex milky, tinged with pale yellowish brown, occiput with blackish brown scales laterally. Labial palpus milky; second segment with fine dark brown line in basal half on outer side; third segment pale brown on outer side. Antenna with scape yellowish white, pale brown on posterior margin; flagellum pale yellowish brown. Thorax and tegula yellowish white, with blackish brown scales basally. Forewing yellowish white, tinged with pale yellowish brown scales, with slender blackish brown streak along costal margin; longitudinal dark brown streak from middle of cell extending to apex, widened from posterior angle of cell to above ventral margin; dark brown streak extending from basal 1/4 of ventral margin obliquely outward to basal 2/5 of fold, then to basal 4/5 of fold; fringe dark brown. Hindwing and fringe brown. Legs milky; fore tibia annulated with black at middle and apex, tarsus annulated with black at apices of first and second tarsomeres, fifth tarsomere black; mid tibia blackish brown and bearing ochreous brown bristles at middle and apex on dorsal surface; hindleg yellowish brown, tibia with long brown hairs on dorsal surface, ringed with long ochreous brown bristles at apex, tarsus annulated with blackish brown and bearing ochreous brown bristles at apices of basal three tarsomeres, fifth tarsomere blackish brown. Eighth segment with two pairs of colcitas in male.
Male genitalia (Fig. 20). Uncus wide at base, narrowly toward apex, with long setae laterally; apex pointed, beak-shaped in lateral view. Gnathos broad at base, slightly narrowed to apex. Tegumen bifurcate from middle; lateral arm narrowed anteriorly. Valva narrow basally; cucullus elliptical, length approximately 2 times of maximum width, smoothly obtuse on dorsal margin, rounded at apex; inner process digitate; costa produced in basal half, narrowly banded in distal half, reaching basal 1/4 of cucullus apically; sacculus elongate conical, approximately 1/3 length of valva, with numerous long spines, free from cucullus distally. Juxta elongate V-shaped, extending obliquely outward posterolaterally, with numerous denticles, obtusely rounded on anterior margin; anellar lobes elliptical (in aedeagus). Aedeagus conical, approximately 5/7 length of valva, gradually tapered from base to apex, with a sclerotized plate at base, produced to a thin club ventrodistally, with numerous microspines ranging from middle to basal 3/4 ventrally; cornutus consisting of five long spines joined basally, ranging from basal 1/4 to middle (Fig. 20a).
Female unknown.
Distribution. China (Guangxi).
Etymology. The specific epithet is derived from the Latin dolichanthus, referring to the long spine-shaped cornuti.
