Diagnosis
This new species is similar to R. spinifera Gorochov, 2013 and R. complanatis, but especially to R. digitata and R. shii. It differs from R. spinifera by the main part of the epiproct compacted (Fig. 1D) instead of elongated; from R. complanatis by digitate processes of the male epiproct cylindrical and shorter (Fig. 1D–E); from R. digitata and R. shii by the distance between the processes of the male epiproct which is significantly longer than the length of the process (Fig. 1D), while in the other species it is nearly equal.
Etymology
The new specific epithet is derived from ‘epiproct’ and the Latinised Greek prefix ‘ hexagoni ’ due to the shape of the main part of the male epiproct in dorsal view.
Material examined

Description
Male
BODY SIZE. Small.
HEAD. Fastigium of vertex divided into pair of plate-like processes by longitudinal furrow (Fig. 1B). Eyes protruding outward, reniform, situated at upper part of external margin of antennal sockets (Fig. 1A); lateral ocelli almost occupying nearly three quarters of lateral margins of whole tubercles, suborbicular, situated at lateral base of tubercles (Fig. 1B); median ocellus situated between two antennal sockets, oval (Fig. 1A). Maxillary palpi stout, apical segment longer than subapical one, apex inflated, almost spherical.
THORAX. Anterior and posterior margin of pronotum slightly convex (Fig. 1B); lateral lobes with ventral margins arched, posterior margins slightly concave (Fig. 1C); posterior margin of mesonotum slightly convex, posterior margin of lateral lobes slightly concave, arched (Fig. 1C); posterior margin of metanotum straight (Fig. 1C).
LEGS. Fore femur with 1 apical spine on internal genicular lobe (Fig. 1B); 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 and 1 pair of apical spines. Hind femur ventrally unarmed, inner genicular lobe with spinule; hind tibia dorsally with 17–18 spinules on both sides, subapical area dorsally with 1 pair of spines, apex with 1 pair of larger mediate spines and 1 pair of smaller ventral spines asymmetrically (always inner one longer), dorsal pair, which is largest one, is missing in the sole specimen (Fig. 1G–H) and seen as pair of circular pits. Hind tarsus laterally compressed, basitarsus dorsally with 5 spinules and 1 terminal spine exceeding ventral edge (Fig. 1G).
ABDOMEN. Abdominal tergite without distinct projection. Posterior margin of tenth abdominal tergite concave. Epiproct roughly hexagonal, with pair of digitative processes (Fig. 1D) in posterolateral corners, and with rather long lobe located between these processes and directed downwards/anteriorly as well as having bispinous apex (maybe due to shrinkage of dry specimen, Fig. 1E–F). Subgenital plate damaged, repaired structure as in Fig. 1H.
COLORATION. Body dark brown with yellowish spots, ventral surface brown, external surface of hind femora with stripes.
Female
Unknown.
