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.

Female

Unknown.
