Diagnosis
The new species is similar to R. spinita and the previous species, but differs from R. spinita by the upper apical part of the epiproct lamellated then diverged to a pair of short spines (Fig. 3D) instead of becoming a pair of long spines directly; and differs from the previous species in the upper apex of the epiproct notched symmetrically (Fig. 3D).
Etymology
The new specific epithet is derived from the Latin ‘ imbrico ’ and ‘ furca ’, and refers to the overlapped forks of the male epiproctal apex.

Description
Male
BODY SIZE. Medium to large.
HEAD. Fastigium of vertex divided into pair of plate-like processes by longitudinal furrow (Fig. 3B). Eyes reniform, situated near upper part of external margin of antennal sockets (Fig. 3A); lateral ocelli almost occupying nearly three quarters of lateral margins of whole tubercles, situated at lateral base of tubercles, oval (Fig. 3C); median ocellus situated between antennal sockets, oval (Fig. 3A). Apical segment of maxillary palpi longer than subapical segment, apex inflated, almost spherical.
THORAX. Anterior margin of pronotum straight, posterior margin of pronotum convex (Fig. 3C), lateral lobes longer than high, ventral margin arched, posterior margin slightly concave (Fig. 3B); posterior margin of mesonotum slightly convex (Fig. 3B); posterior margin of metanotum almost straight.
LEGS. Fore coxa dorsally with spine; fore femur with 1 apical spine on internal genicular lobe (Fig. 3A); fore tibia ventrally with 2 external spines, 1 internal spine and 1 pair of apical spines. Anterior margin of middle coxa dorsally with 1 spinule; middle femur with 1 long apical spine on internal and external genicular lobe separately; middle tibia dorsally with 3 external and 2 internal spines, ventral surface with 2 external and 1 internal spine, apex with 1 pair of spines dorsally and ventrally separately. Hind femur ventrally unarmed, inner genicular lobe with 1 spinule; hind tibia dorsally with 22 spinules on both sides, 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, largest apical spine broken (Fig. 3G); hind tarsus laterally compressed, basitarsus dorsally with 4 spinules and 1 long terminal spine longer than ventral edge (Fig. 3G).
ABDOMEN. Each abdominal tergite without processes. Base of epiproct almost trapezoidal; its more distal portion directed downwards, divided into lamellar upper (posterior) and lower (anterior) parts: upper part narrower, narrowest in distal third, with apex deeply and angularly notched as well as forming pair of diverged spines (Fig. 3D); lower part wider, apically with more rounded notch and pair of lateral (shorter than above-mentioned spines) hooks (Fig. 3E–F). Apex of subgenital plate almost angular, sub apex with 1 pair of styli almost cylindrical (Fig. 3F).
COLORATION. Body darkish brown. Head dorsally darkish, face pale, within antennal sockets with 1 pair of blackish patches, below eyes with 1 pair of darkish patches almost circular; eyes blackish brown, ocelli pale. Legs yellowish brown, genicular lobes darkish; basal half of hind femora with oblique yellowish stripes on external margin, dorsal surface with pale patches; spines of hind tibiae blackish.
