Diagnosis. The new species is similar to R. fopingensis and R. mediprocessa sp. n. in male genitalia. It can be distinguished by the stout uncus without lateral lobes, the semicircular gnathos, and the aedeagus trilobed distally. In R. fopingensis , the slender uncus has a rounded setose lobe laterally, the gnathos is roughly X-shaped, and the aedeagus has two pointed lobes distally. For differences between R. trilobata sp. n. and R. mediprocessa sp. n. see diagnosis under the latter species.
Description. Adult ( Fig. 14 View FIGURES 9–14 ). Wingspan 10.0 − 13.0 mm.
Head with frons yellowish white, vertex brown. Labial palpus pale yellow, second palpomere black distally; third palpomere in female black except yellow at apex. Antenna black on dorsal surface; scape yellow and flagellum brown on ventral surface.
Thorax and tegula dark brown. Forewing dark brown; costal spot yellow, sub-triangular, placed at distal 1/5; discal, discocellular and plical stigmata black, edged with a whitish yellow stripe or a few whitish yellow scales; fringe black. Hindwing dark grey; fringe greyish brown, with a whitish yellow basal line. Legs yellow; on dorsal surface, femur and tibia of foreleg dark brown, tibia of midleg black, with a yellow stripe at middle, tarsi of fore- and midlegs black at middle of first tarsomere and at base of second tarsomere as well as on entire third and fourth tarsomeres; on outer surface, tibia of hindleg black, tarsus black at middle of first tarsomere and at base of other tarsomeres.
Male genitalia ( Fig. 26 View FIGURES 21–26 ). Uncus relatively stout, broad at base, narrowed to basal 1/3, subparallel to truncate apex. Gnathos ring-like. Valva narrowed at base, gradually widened to basal 1/3, subparallel from basal 1/3 to obtusely rounded apex; costa banded, reaching middle length of costal margin; transtilla lobes uniformly banded, extending obliquely dorsad, joined mesially by membrane; sacculus slightly shorter than 1/3 length of valva, subtriangular, narrowed from wide base to apex, with a small apical spine hooked dorsad. Saccus triangular, apex obtusely rounded. Juxta narrowly banded; lateral arm slender, curved. Aedeagus longer than 2/3 length of valva, almost tubular, trilobed distally: first divided into two lobes from middle, one lobe furcate distally.
Female genitalia ( Fig. 32 View FIGURES 27–32 ). Apophyses anteriores about half length of apophyses posteriores. Eighth sternal plate relatively narrow. Antrum slightly widened posteriorly. Ductus bursae membranous, not distinctly separated from corpus bursae. Corpus bursae elongate elliptical, without signum.
Distribution. China (Fujian, Zhejiang).
Etymology. The specific epithet is from the Latin tri- and lobatus, referring to the distally trilobed aedeagus.
