Diagnosis
The new species is rather similar to R. brevispinula Bian, Zhu & Shi, 2017, R. spinita and R. quadrispina, but differs from them by the upper apical half of the epiproct lamellated and irregularly incised at the terminal end, instead of becoming a pair of separated spines (Fig. 2D).
Etymology
The new specific epithet is derived from the Latin ‘ dens ’ and the Latinised Greek prefix ‘ hetero -’, referring to the irregular tooth of the upper apex of the male epiproct.

Description
Male
BODY SIZE. Medium.
HEAD. Fastigium of vertex divided into pair of plate-like processes by longitudinal furrow (Fig. 2B). Eyes protruding outward, reniform, situated at upper part of external margin of antennal sockets (Fig. 2A); lateral ocelli suborbicular, situated at lateral base of tubercles (Fig. 2B); median ocellus situated between two antennal sockets, oval (Fig. 2A). Maxillary palpi strong, apical segment longer than subapical one, apex inflated, almost spherical (Fig. 2C).
THORAX. Anterior and posterior margin of pronotum slightly convex (Fig. 2B), lateral lobes with ventral margins arched, posterior margins slightly concave (Fig. 2C); posterior margin of mesonotum slightly convex, posterior margin of lateral lobes slightly concave, arched (Fig. 2C); posterior margin of metanotum straight.
LEGS. Fore femur with 1 apical spine on internal genicular lobe (Fig. 2B); fore tibia ventrally with 1 internal spine, 2 external spines and 1 pair of apical spines. Middle femur with 1 apical spine on internal and external genicular lobe separately; middle tibia dorsally with 2 pairs of spines and 1 pair of apical spines, ventrally with 2 external spines, 1 internal spine and 1 pair of apical spines. Hind femur ventrally unarmed, internal genicular lobe with 1 spinule; hind tibia dorsally with 21 external spinules and 20 internal spinules, subapical area dorsally with 1 pair of spines; apex with 1 pair of long dorsal spines, 1 pair of short ventral spines and 1 pair of medium long mediate spines asymmetrically, tip of the longest apical spine exceeded tip of metatarsal terminal spine (Fig. 2G–H). Hind tarsus laterally compressed, basitarsus dorsally with 5 spinules and 1 terminal spine exceeding ventral edge (Fig. 2G). ABDOMEN. Posterior margin of tenth abdominal almost straight. Basal portion of epiproct subquadrate, upheaved aside middle (Fig. 2D–E); its more distal portion curved downwards and consisting of 2 parts: upper (posterior) part lamellar, elongate, narrowing to irregularly notched apex having pair of rather narrow and angular lateral lobules; lower (anterior) part wider than upper one and widely divided into pair of decurved hooks (Fig. 2F). Posterior margin of subgenital plate wide, widely concave in middle, subapical with 1 pair of styli (Fig. 2E); styli almost conical, basal half wide, apical half slender, apex acute. COLORATION. Body reddish brown, ventral surface yellowish brown. Scape and pedicel of antennae pale brown, flagellum darkish in dorsal surface. Eyes darkish brown, ocelli pale. Legs pale brown, external surface hind femur with darkish stripes and pale spots. Spines of hind tibiae darkish.
