Figs 3A–L
Type material. Holotype. male; Hunan Prov., Chenzhou City, Mangshan National Forest Nature Reserve; 4 Jun. 2019; Rong Chen, Jian-Yue Qiu leg. Paratypes. 5 males; same collection data as holotype; 12 males; Hunan Prov., Chenzhou City, Mangshan National Forest Nature Reserve; 3 Jun. 2019; Rong Chen, Jian-Yue Qiu leg.
Differential diagnosis. This new species generally resembles R. sinensis Walker, 1868, but can be distinguished from R. sinensis by the following characters: 1) abdomen dark brown, in R. sinensis it is yellowish brown; 2) sclerite L3 has no high carina on the outer-lateral margin and no groove on the inner margin, whereas in R. sinensis sclerite L3 has a high carina on the outer-lateral margin and groove on the inner margin.
Description. Measurements (mm). Overall length: male 36.5–39.0; pronotum length × width: male 6.3–6.9 × 8.2–9.3; tegmen length × width: male 32.1–34.6 × 9.7–11.2.
Male. Head black except yellowish white ocelli, apex of labrum and clypeus brown; maxillary palps dark brown; antennae with about 10 basal segments black, the rest brown (Fig. 3B). Pronotum reddish brown, with small, scattered brown spots, and a row of longitudinal stripes on posterior margin (Fig. 3C). Tegmina brown, densely scattered with irregular white maculae. Hind wings with veins brown, costal field, radial field and mediocubital field yellowish brown, anal field pale brown (Fig. 3F, G). Legs brown.Abdominal terga and sterna dark brown. Supraanal plate and subgenital plate dark brown, cerci and styli dark brown (Fig. 3B).
Vertex slightly exposed. Distance between eyes approximately equal to the interocellar width, smaller than the space between antennal sockets (Fig. 3B). Pronotum transverse and almost pentagonal, with anterior margin gently arc-shaped, lateral margins convexly rounded, middle of posterior margin obtusely produced, widest about the middle (Fig. 3C). Tegmina and wings fully developed extending well beyond end of abdomen and venation distinct (Fig. 3A, B, F, G). Anteroventral margin of front femur Type B 2 (Fig. 3D). Hind metatarsus nearly equal to the remaining segments combined, with two equal rows of ventral spines; pulvilli present apically on all tarsomeres; tarsal claws symmetrical and unspecialized, with large arolia (Fig. 3E). Abdominal tergites unspecialized. Supraanal plate symmetrical with small bristles; the middle of the hind margin slightly concave with a cluster of long bristles, lateral margins slightly arc-shaped. Paraprocts dissimilar, left paraproct with a finger-like bulge bending inward. Cerci distinctly segmented and densely covered with bristles (Fig. 3H). Subgenital plate slightly concave and almost symmetrical, the base of the inner plate bifurcated, styli flat, apically rounded (Fig. 3L).
Male genitalia. Right phallomere with caudal part of sclerite R1T almost rectangular; end of sclerite R2 rounded; R3 and R5 interlinked; base of R3 turned over; R4 irregular and existed independently (Fig. 3I). The basal part of sclerite L2D slender and rod-shaped; the apical part short and small, nearly rectangular, with chaetae-covered membrane (Fig. 3J). Sclerite L3 hooked and deeply bent, outer-lateral margin smooth with low carina; inner margin toothless but with a large conical projection at base (Fig. 3K).
Female. Female unknown.
Etymology. The species name “ equalisinensis ” reflects its similarity to R. sinensis Walker, 1868.
