Paratypes: Yunnan Province: 24♂, 23♀, same data as holotype except dated 11–12.VIII.2014; 1♂, Mt. Xiaohei, Longling County, 2300 m, 10.VIII.2005, coll. Yingdang Ren, genitalia slide No. ZYM06287.

Description. Adult (Fig. 3 b) with wingspan 15.0 mm. Head yellowish white. Antenna brown with white. Labial palpus with second segment yellowish brown except white terminally; third segment ocherous brown on inner surface, grayish white on outer surface. Thorax yellowish brown; tegula pale yellow, with brown scales. Forewing with costal margin slightly arched, apex bluntly rounded, termen oblique; ground color ocherous yellow, sparsely mixed with brown scales; markings blackish brown: humeral patch extending to basal 1/5; costal patch wedge-shaped, at basal 2/5; median patch sub-semicircular, extending from below upper margin of cell to dorsum, its lower margin about 1/3 length of dorsum, outer margin rounded; discocellular stigma, narrow rectangular bar, slightly narrowed medially; subterminal patch trapezoidal, its inner margin about 1/5 length of outer margin, outer margin extending from costa to dorsum; narrow black stripe extending from before lower angle of cell along CuA2 to dorsum at distal 1/5; subterminal fascia grayish yellow, slightly arched outwardly at anterior 2/5, followed by a broad zone with scattered dark brown scales; distinct blackish brown line extending from upper corner of subterminal patch to tornus; fringe pale yellow. Hindwing and fringe grayish yellow. Fore leg yellowish brown, with black scales; mid leg blackish brown except tarsus with white apex; hind leg with femur grayish brown, tibia yellowish white, dark brown before apex, tarsus yellowish white, with scattered pale brown scales.
Male genitalia (Fig. 5 c): Uncus with basal 1/3 nearly triangular, distal 2/3 narrowed, curved toward ventral surface, pointed apically. Gnathos broad in basal 2/3 and parallel sided, distal 1/3 sharply narrowed to a pointed tip, hooked. Valva broad in basal 1/3, more than twice width of median part; costa deeply concave medially; ventral margin with basal half arched, distal half straight; cucullus foot-shaped, slightly narrowed to rounded apex, outer margin obliquely straight, ventro-distal corner right-angled; sacculus broad at base, conspicuously narrowed to end, about 1/4 length of valva. Juxta square, anterior 1/4 with an imbricated process medially, caudal margin slightly convex medially; caudal lobe subtriangular, dentate on outer margin. Vinculum narrowly banded. Aedeagus stout, straight, slightly shorter than valva, with four short spines on ventral margin preapically; cornuti consisting of a cluster of spinules and one sclerotized plate medially, a patch with dense thorns from 3/5 to 4/5, and numerous teeth forming a circle apically.
Female genitalia (Fig. 7 e): Abdominal sternite VIII with caudal margin concave medially. Apophyses posteriores about twice length of apophyses anteriores. Antrum trapezoidal, with a bunch of spinules. Ductus bursae slightly longer than corpus bursae; ductus seminalis arising from posterior 1/3 of ductus bursae. Corpus bursae elongate oval; two signa placed in posterior half, one crescent, one subrectangular, with dense spines.
Diagnosis. This species can be distinguished from its congeners by the aedeagus having a distal circle formed by numerous teeth and with four strong dorso-apical dentations in the male genitalia; and by the corpus bursae with a crescent and a subrectangular signa placed posteriorly in the female genitalia.
Distribution. China (Yunnan).
Etymology. The specific name is derived from the Latin gyroflexus (circular), referring to the distal circle of aedeagus formed by numerous teeth.
