Diagnosis

This species differs from R. sichuanensis in the dorsal surface of the male epiproct with 2 crooked carinae, surface between carinae with oval concave (Figs 4D, 5A), while R. sichuanensis has almost straight but unparallel carinae, surface between carinae with narrower, shallower and longer concave. The new species differs from R. xishuang in having few basitarsal spines and basal one third of male epiproct with broader concave.

Etymology

The new specific epithet is derived from the Latinised Greek ‘ glene ’ and refers to the small pit of the male epiproctal terminal.

Description

Male

BODY SIZE. Medium.

HEAD. Fastigium of vertex divided into pair of plate-like processes by longitudinal furrow (Fig. 4B). Eyes protruding outward, reniform, situated near upper part of external margin of antennal sockets (Fig. 4A); lateral ocelli almost occupying half of lateral margins of whole tubercles, situated at lateral base of tubercles, suborbicular (Fig. 4C); median ocellus situated between antennal sockets, oval (Fig. 4A). Maxillary palpi stout, apical segment nearly equal to subapical segment, apex inflated, almost spherical (Fig. 4C).

THORAX. Anterior margin of pronotum straight, posterior margin of pronotum convex (Fig. 4B), posterior part of ventral margin of lateral lobes arched, posterior margin slightly concave (Fig. 4C); posterior margin of mesonotum distinctly convex; posterior margin of metanotum straight (Fig. 4C).

LEGS. Fore coxa inflated, dorsally with 1 spinule; fore femur with 1 apical spine on internal genicular lobe (Fig. 4H); fore tibia ventrally with 2 external spines, 1 internal spine and 1 pair of apical spines. Middle coxa dorsally with 2 spiniform processes; 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, with 1 spinule on internal genicular lobe; hind tibia dorsally with 17–18 spinules on both sides, subapical area dorsally with 1 pair of spines, apex with 1 pair of long dorsal spines and 2 pairs of ventral shorter spines asymmetrically, largest-apical spine exceeding tip of metatarsal terminal spine (Fig. 4G); hind tarsus laterally compressed, basitarsus dorsally with 1 spinule and terminal spine (Fig. 4G).

ABDOMEN. Abdominal tergite without obvious projection, posterior margin of tenth abdominal tergite concave (Fig. 4D). Epiproct simple, more or less triangular but slender, with basal part wider than apical part, basal three fifths having elongate pale oval concavity between pair of dorsolateral carinae, and small dorsomedian pit along apical fourth of epiproct behind convergence of lateral carinae (Figs 4D, 5). Subapical part of subgenital plate with 1 pair of styli, nearly cylindrical, apex acute (Fig. 4E), styli longer than distance between them (Fig. 4D). Cerci slender, subconical, apex obtuse (Fig. 4E).

COLORATION. Body reddish-brown, face light, eyes dark, ocelli light. Legs yellowish-brown, external surface of hind femora with oblique stripes.
