ḚNJẍDz Figures 10–11 Description. Male. Body medium. Head and pronotum as other species of the genus. Fore coxae with 1 spine; femora with 1 short ventral spine on internal margin; tibiae with 1 internal and 2 external spines ventrally, apices with 1 pair of spines on ventral surface. Middle femora with 1 pair of apical spines on ventral surface; tibiae dorsally with 2 pairs of spines, ventral surface with 1 internal and 2 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind femora with 1 short ventral spine on internal margin; tibiae dorsally with 18–19 internal spines, 20–22 external spines and 1 pair of small subapical spines; tibial apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 4–5 small spines and 1 apical spine on dorsal surface along the midline ( Fig. 10D ). Posterior margin of tenth abdominal tergite concave. Epiproct with basal margin straight; lateral margins of basal half convex, then prolonged into 1 pair of processes, between the processes triangular ( Fig. 10G, H ); before of the processes with 1 pair of spines, which equal length ( Fig. 10H, I ); basal half of dorsal surface concave, apical half with median furrow ( Fig. 10H ); ventral surface of epiproct nearly rectangular, the lateral margins raised with subbasal areas concave, and terminating into 1 pair of spines at apical area, the posterior margin between the spines almost straight ( Fig. 10K, L ). Paraprocts prolonged into a short spine, apex acute ( Fig. 10E ). Subgenital plate wider than long, lateral margins convex, posterior margin arched projecting between styli; styli conical, apical area sclerotized and incurved, inserted on posterolateral area of the plate ( Fig. 10J ).

Female. Posterior margin of tenth abdominal tergite semi-ovally concave in middle ( Fig. 11H ). Epiproct longer than wide, lateral margins convex, dorsal surface concave with apical area furrowed along the midline, the lateral sides obtuse ( Fig. 11H ). Cerci slender, apices subacute. Subgenital plate wider than long, lateral margins convex, posterior margin widely rounded with 1 small angle in middle ( Fig. 11I ). Ovipositor slightly shorter than hind femora, moderately upcurved, apices acute; dorsal margins smooth, subapical area of ventral margins serrate ( Fig. 11J ). Coloration. Body brown with irregularly black patterns, terga with small black-brown spots, sterna yellowish brown. FIGURE 12. Rhaphidophora longitabula Bian, Zhu & Shi, 2017 .

Discussion. The new species differs from other species of Rhaphidophora by male epiproct prolonged with 1 pair of spines at subapical area and 1 pair of processes at apical area ( Fig. 10G, H ), ventral surface subrectangular with 1 pair of spines at apical area ( Fig. 10K, L ); male paraprocts prolonged into a short spine ( Fig. 10E ); male subgenital plate with apical area sclerotized; female subgenital plate angularly projected in middle at posterior margin ( Fig. 11I ). Etymology. The name of the new species refers to the middle area of male epiproct dorsally with 1 pair of spines which equal in length; from Latin word “ equal ” and “ spin ”.
