( Figs 12 View FIGURES 9–14 , 24 View FIGURES 21–26 , 30 View FIGURES 27–32 )
Type material. CHINA, Yunnan: Holotype ♂, Xin Village (24.87°N, 98.75°E), Tengchong, 2116 m, 11.VIII.2014, leg. KJ Teng et al., slide No. LiSR16284. GoogleMaps
Paratypes: Yunnan: 2♀, same data as holotype except dated 11–12.VIII.2014, slide Nos. LiSR16283, LiSR16299 GoogleMaps .
Diagnosis. The new species is diagnostic by the V-shaped juxta with very wide lateral arms. It is similar to R. acerba sp. nov., and the differences between them are stated in the diagnosis of the preceding species.
Description. Adult ( Fig. 12 View FIGURES 9–14 ). Wingspan 15.0 – 16.5 mm.
Head brown. Labial palpus yellow; second palpomere in male dark brown from beyond middle to near apex on ventral surface, in female dark brown on ventral surface, with a black apical ring. Antenna with scape yellow, tinged with black scales; flagellum black on dorsal surface, dark brown and yellow on ventral surface.
Thorax and tegula black. Forewing dark brown; costal spot yellow, at distal 1/4; discal, discocellular and plical stigmata black; fringe dark brown, with a yellow basal line. Hindwing and fringe greyish brown. Foreleg yellow, on dorsal surface, tibia blackish brown, first tarsomere dark brown at middle and second tarsomere dark brown at base; coxa and femur of midleg yellow, tibia and tarsus yellow on ventral surface, tibia dark brown on dorsal surface, tarsus dark brown except yellow at base of first tarsomere, at apices of first and second tarsomeres as well as on entire fifth tarsomere; hindleg yellow, tibia and tarsus with blackish brown scales on outer surface.
Male genitalia ( Fig. 24 View FIGURES 21–26 ). Uncus membranous, subcylindrical, slightly narrowed to obtusely rounded apex. Gnathos ring-like, weakly sclerotized. Tegumen wide medially, with a semicircular anterior emargination; lateral arm narrowed to a point, slightly longer than median width. Valva with basal 2/5 subparallelly sided, slightly widened from basal 2/5 to obtusely rounded apex; costa banded, narrowed distally, reaching near tip of costal margin; transtilla lobes cup-shaped horizontally, uniformly slender basally, expanded distally, joined mesially by membrane; sacculus wide at base, narrowed to basal 3/5, distal 2/5 abruptly narrowed to a digitate process. Saccus triangular. Juxta broadly V-shaped; lateral arm gradually widened from base to basal 3/4, then narrowed, apically extending outward and narrowed to a point. Aedeagus longer than 2/3 length of valva, basal 1/5 thickened, distal 4/5 tubular, obtusely rounded at apex; elliptical sclerite extending from distal 1/4 to apex, with a stout spine hooked backward.
Female genitalia ( Fig. 30 View FIGURES 27–32 ). Apophyses anteriores slightly longer than half length of apophyses posteriores. Eighth sternal plate sub-trapezoidal, slightly concave at middle on posterior margin. Lamella antevaginalis quadrate, concave semicircular on posterior margin. Antrum narrowed medially. Ductus bursae shorter than corpus bursae, membranous. Corpus bursae elliptical; signum sub-rectangular, with dense teeth.
Distribution. China (Yunnan).
Etymology. The specific epithet is derived from the Latin hamatus and spina, referring to the hooked apical spine of the aedeagus.
