Description

BODY. Length: 1.5–1.8 mm. Eye height 2.5 × genal height. Head with 3 interfrontal setae and 5–6 small setae along inner margin of orbital plate. Gena with 2 strong setae and 7–9 smaller setulae. Acrostichal setulae in 4–6 rows. Costagial seta extending slightly beyond humeral break; second costal sector equal to third sector; length of M 1 between crossveins dm-cu and r-m 2.0× dm-cu; CuA 1 stub vein ~5.0 × M 1 stub vein. Male mid femur with 4–5 small setae in ventrobasal cluster. Male mid tibia with ventral comb of 7–8 robust setae on apical ½, midventral seta absent (female unknown).

MALE ABDOMEN ( Fig. 18 View Fig ). Sternite 3 and 4 with dense cluster of setae posteromedially. Posterior margin of sternite 5 with round teeth on each side of a medial emargination; emargination less than 1/6 width of sternite and extending ~½ length. Transverse part of sternite 6 weakly arcuate. Epandrium with one large pair of setae ventrolaterally, one smaller pair of setae lateral to larger pair, and several setulae scattered over surface; subanal plate broadly continuous below anal opening. Surstylus boot-shaped, posteriorly bent near base, hirsute with 3–5 setae on posterior lobe (heel) and numerous smaller setae on anterior lobe (toe). Cercus fused with epandrium, with distinct seta on ventral margin. Postgonite clavate, with several setulae on dorsal surface. Dorsal sclerite of distiphallus ( Fig. 18 View Fig D–F) without distinct swellings and not extending beyond apex of acrophallus.

Female

Unknown.

Remarks

This species is most similar to R. newtoni   sp. nov., which also has a setulose male sternite 4 and sternite 5. These species are easily distinguished by the shape of the male surstylus.
