( Figs. 3, 6 )

Holtoype Male. China, Mt. Daming (23°54' N, 108°37' E), Guangxi Zhuangzu Autonomous Region, 40 m, 27.IV.2014, leg. Tengteng Liu, Wei Guan & Xuemei Hu, genitalia slide no. LKL13204.

Diagnosis. This species possesses a typical Sorolopha forewing pattern. It is similar to S. camarotis (Meyrick, 1936) in the male genitalia, but it can be distinguished from the latter species by the gnathos aciculate medially, the sacculus with two adjacent bristle clusters with the short one situated on the ventral part, and the cucullus lacking a ventral prominence and bearing one strong thorn. In S. camarotis the gnathos is naked, the two clusters of bristles of the sacculus are not adjacent with the short one situated on the disc, and the cucullus has a ventral prominence which bears four strong thorns.

Description. Adult ( Fig. 3 ). Head: Vertex roughly scaled, fuscous. Antenna fuscous. Labial palpus porrect, fuscous; median segment expanded distally.

Thorax: Fuscous; posterior crest distinct, blackish fuscous suffused with brown. Hind tibia in male unmodified, lacking hair pencil. Forewing length 6.0 mm; costa slightly arched, apex blunt, termen oblique; upperside ground color leaden, markings blackish fuscous, with white or ochreous margin; costal strigulae leaden suffused with white; basal fascia indicated by a few small broken patches; subbasal fascia represented by a small patch below costa and a large triangular blotch between base of M-stem and basal 1/4 of dorsum; median fascia oblique, gradually broadened backward, proximal edge concave, reaching mid-length of dorsum at 4/5 length of Sc, base of R1, and 3/5 length of 1A+2A, distal edge extending from mid-length of costa to 1/4 length of M3, and then to end of dorsum, lower part of media fasica divided into two parts below CuA2, inner part narrow, about 1/3 width of outer part; postmedian fascia with two small patches below costa, with broad ochreous margin; preterminal fascia represented by a line below costa, extending outward and confluent with terminal fascia; terminal fascia a small dot; large and somewhat rounded spot set between R4 and CuA2, inner edge extending from mid-length of R4 to 1/3 length of M2, then to 3/4 length of CuA1, finally reaching termen, outer edge reaching termen between M1 and CuA2, connecting with terminal fascia, and extending along termen to tornus; cilia fuscous; underside brownish fuscous except grayish white area overlapped by hindwing. Hindwing upperside fuscous except grayish white area overlapped by forewing; cilia pale grey; underside concolorous with forewing.

Abdomen: Male genitalia ( Fig. 6 ) with tegumen high. Uncus obtuse. Socius slender, about 2/3 length of tegumen, apex slightly dilated and bearing slender thorns. Gnathos weak, median portion aciculate. Valva slender; neck naked; sacculus lacking ventral angle, spined, and with two adjacent bristle clusters medially, spines of inner cluster very long, those of outer cluster short; cucullus slender and spined, base with a short lobe and with dense patch of short spines, slightly protruding ventrally at 1/2 length and bearing one strong thorn. Phallus curved, cornuti absent.

Female unknown.

Etymology. The specific name is derived from the Latin singularis (= single), referring to the number of the strong thorns on the cucullus in the male genitalia.
