Type material. CHINA, Hubei: Holotype ♂, Quanxi Town (32.03°N 109.69°E), Zhuxi County, 868 m, 9.VII.2017, leg. WD Qi et al., slide No. XZX20323. GoogleMaps
Diagnosis. The new species is similar to R. bicruris Wang & Li, 2003 in male genitalia. It can be distinguished by the broad triangular saccus, and the aedeagus has an apical spine. In R. bicruris , the slender saccus is sub-digitate, and the distally bilobed aedeagus lacks an apical spine.
Description. Adult ( Fig. 4 View FIGURES 3–8 ). Wingspan 10.0 mm.
Head pale yellow, vertex mixed with black scales. Labial palpus in male yellow, second palpomere with black scales distally. Antenna yellow; flagellum ringed with brown on dorsal surface.
Thorax and tegula black basally, yellow distally. Forewing yellow, with black scales; costal margin dark brown from base to basal 1/3, forming a dark band widened toward apex, diffused dark brown spot from between basal 2/5 and distal 1/3 to anterior margin of cell, darker at each side, three small dark brown dots in distal 1/4; terminal dots black, running along termen to tornus; discal, discocellular and plical stigmata black, discocellular stigma doubled, closely placed one above the other; dorsum with a black spot at base; fringe yellow, except on extension of black marginal dots. Hindwing and fringe dark brown. Legs yellow; on dorsal surface, femur of foreleg black, tibia black, ringed with yellow at basal 1/3, at middle and at apex, tarsus black at middle of first tarsomere and at base of second tarsomere as well as on entire third and fourth tarsomeres; tibia of midleg black, with yellow speckle at basal 1/3, at middle and at apex, tarsus black at middle of first tarsomere and at base of other tarsomeres; femur of hindleg with black scales, on outer surface, tibia of hindleg black, tarsus black at middle of first tarsomere and at base of second tarsomere.
Male genitalia ( Fig. 16 View FIGURES 15–20 ). Uncus sub-trapezoidal, shrunk near apex laterally, mushroom-like apically, with a few setae beyond middle laterally. Gnathos with ventral plate horizontally straight, narrowly banded, slightly widened anteriorly, pointed at each tip; basal arm banded, as long as width of ventral plate. Tegumen quadrate posteriorly, with a semicircular anterior emargination; lateral arm shorter than median width. Valva narrowly elongate, slightly widened from near base to before obtusely rounded apex, with setae from basal 1/5 to 1/2 above ventral margin; costa narrowly banded, reaching beyond middle of costal margin; transtilla lobes expanded near middle, weakly joined mesially; sacculus triangular, with sparse long setae at apex. Saccus triangular, apex narrowly rounded. Juxta U shaped; lateral lobes broadly banded, slightly narrowed to finely serrate apex. Aedeagus as long as valva, with an apical spine.
Female unknown.
Distribution. China (Hubei).
Etymology. The specific epithet is derived from the Latin apicalis and s pina, referring to the apical spine of the aedeagus.
