Diagnosis. This species is similar to R. relicta (Kuznetsov, 1968) in forewing pattern and in the shape of uncus, but can be distinguished by the broad and strongly dilated cucullus in relation to the neck of the valva, and the sacculus with two lobes in the male genitalia; and the corpus bursae with a slender, inverted V-shaped sclerite and two signa in the female genitalia. In R. relicta the cucullus is slightly dilated in relation to the neck of the valva, and the sacculus lacks lobes; and the corpus bursae has a short, inverted cup-shaped sclerite and only one signum.
Description. Adult ( Fig. 2 View FIGURES 1 – 5 ). Head: Vertex with grayish brown scales, frons white. Antenna brown. Labial palpus grayish brown, third segment gray and porrect. Thorax: Dorsum and tegula grayish brown. Forewing length 5.5-6.5 mm; upperside ground color gray; basal and subbasal fasciae fused to form a large, pale brown basal patch, extending from costal 1/3 to 2/5 of dorsum, protruding medially on outer margin; median fascia extending from costal half to before tornus; speculum silvery, irregular, with some brown spots; costa with nine pairs of white strigulae from base to apex: strigulae 1-4 slightly faint, between base and the point where Sc meets costa; strigulae 5 and 6 between Sc and R1, composed of only one short stria; distal three pairs distinct, distributed between pairs of veins R1-R2, R2-R3, R3-R4, confluent with strigulae 5-6; postmedian fascia and striae to termen below apex; cilia grayish brown. Hindwing upperside and cilia dark gray. Foreleg brown; midleg dark gray, tibia and tarsus with brown scales; hindleg gray, with brown scales on tarsus. Abdomen: Male genitalia ( Fig. 7 View FIGURES 6 – 10 ) with uncus bearing bifid, clubbed arms, slightly bending outwards, dilated toward base and blunt on end; socius reduced to a broad triangular process, hairy. Valva slightly broad at base, ventral margin distinctly concave at about middle; neck short; sacculus with tufted hairs and two mound-like lobes; cucullus broad and short, nearly quadrate, apex round, hairy, with small, thick, marginal setae and some stout setae ventrobasally. Phallus tubular; cornuti consisting of a bunch of slender spines. Female genitalia ( Fig. 11 View FIGURES 11 – 13 ) with papilla analis slender, hairy, narrowed anteriorly; posterior apophysis as long as anterior apophysis. Sternite 7 broadly sclerotized, concave on posterior margin. Ostium nearly quadrate; sterigma narrow, surrounding ostium except on anterior margin, straight posteriorly, produced into two elongate triangular sclerites at sides of ostium. Ductus bursae sclerotized in basal half, membranous in distal half. Corpus bursae pyriform, with a slender, inverted V-shaped sclerite extending from entrance of corpus bursae to posterior 2/5 along sides; two spine-like signa present.
Holotype. Male, CHINA: Fujian Province: Mt. Wuyi (26.54˚N, 116.42˚E), 1000 m, 26.v. 2004 (Haili Yu), genitalia slide no. ZAH04221.
Paratypes. 1 male, 5 females, same data as holotype; 5 males, 6 females, same data as holotype, except 600~ 1100 m, 23-27.v.2004.
Etymology. The specific name is derived from the Latin bilobus = bilobed, referring to the sacculus with two mound-like lobes.
