Description. Measurements (mm), male Overall length 20.2–20.5; head length × width 2.5–2.7 × 2.4–2.7; prOnOtum length × width 4.1–4.3 × 5.2–5.5; tegmina length × width 17.2–17.8 × 5.2–5.5.
Male. BOdy yellOwish-brOwn. Eyes dark brOwn. Ocelli pale yellOwish. Antennae yellOwish-brOwn. Vertex and space between Ocellus with mOstly small and a few large dark dOts, clypeus and labrum unmarked, frOns with fOur small dark dOts, fOrmatiOn arc-shaped (Fig. 2). Distance between eyes abOut 1.3 times Of Ocellus. Maxillary palp withn 1st–2nd segments pale yellOwish and 3rd–5th segments brOwn. Tegmina and wings brOwnish yellOw, veins yellOwish, subcOstal vein pale yellOwish. AbdOminal sterna yellOw, Cerci yellOwish, apical segment dark (Figs. 1– 2 & 18).
PrOnOtum subpentagOnal, smOOth and impunctate, pOsteriOr margin Obtusely prOduced, cOvered with mOstly small and a few larger dark dOts, pOsteriOr margin with large black dOts. Tegmina and wings with rOund apex surpass the abdOmen. The median vein Of the tegmina presents dark spOts On its basal third and weakly brOwn spOts On its distal third (Fig. 1). COxa, femur and abdOmen with dark brOwn spOts (Fig. 2). AbdOminal sterna with small and fewer large black dOts, large black dOts alOng the hind margins Of the segments. FOre femur type B2, with fOur tO five large spines alOng anteriOr margin and twO apical spines (Fig. 23). First hind tarsOmere with spines alOng mOst part Of its length, lOnger than the Other segments cOmbined. Spinules On euplantula exist. Tarsal claws symmetrical, simple, arOlia well develOped (Fig. 21). AbdOminal terga unspecialized. Supra-anal plate nearly triangular, with Oblique lateral margins and shallOw caudal emarginatiOn. ParaprOcts blaberid-type, asymmetrical (Fig. 20). Hypandrium widely cOnvex On pOsteriOr margin, with a small dOrsally directed triangular tOOth near the middle, styli similar (Fig. 19).
Male genitalia. Right phallOmere with caudal part Of sclerite R1T quadrate (Fig. 24, c.p.R1T), cranial part Of R1T (Fig. 24, cr.p.R1T) and R2 rOunded; R3 with twO branches, left branch mOre wider than right, strOngly sclerOtized; R5 wide, plate-like, weakly sclerOtized (Fig. 24). L2D divided intO basal and apical parts, basal part rOd-like, widened cranially, apical part with a spinOus prOcess On the right (Fig. 22). Sclerite L3 elOngated, with an apical incisiOn, "fOlded structure" distinct, with bristles (visible at a large magnificatiOn) (Fig. 25, f.s.).
Female unknOwn.
Comparison. R. hainanensis sp. n. is similar tO R. annamensis (Figs. 3–8 & 13–16) Of which detailed descriptiOn was given by ROth (1999), but can be distinguished by the fOllOwing characters: 1) One third Of median vein frOm base with dark spOts, at the base Of the anal vein withOut dark macula, prOnOtum pOsteriOr margin withOut semicircular blOtch (At the base Of the anal vein with a dark macula near the semicircular dark blOtch On the pOsteriOr margin Of prOnOtum in R. annamensis (ROth 1999) (Figs. 1, 3 & 7); 2) The shape Of apical part Of sclerite L2D different (Figs. 13 & 22). 3) The bOdy cOlOr mOre yellOw than R. annamensis; prOnOtum, head and abdOminal sterna with dark spOts, R. annamensis with brOwn spOts (Figs. 1, 3 & 7).
