石氏Ēȃ

Figs 14–15

Description. Male. Body medium. Median ocellus as large as lateral ocelli (Fig. 14A–B). Apical segment of maxillary palpi longer than subapical segment, apices slightly inflated. Anterior margin of pronotum arched, posterior margin widely rounded (Fig. 14B). Fore coxae obviously inflated, with 1 laterally compressed 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 3 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind tibiae dorsally with 17–19 spines, 1 small subapical spine and 1 apical spine on both sides, ventral surface with 2 pairs of apical spines; basitarsi with 5 spines and 1 apical spine on dorsal surface along the midline (Fig. 14K). Abdominal tergites without any processes. Epiproct directing downwards, the basal two thirds nearly rectangular, the lateral margins convex, dorsal surface smooth (Fig. 14E); the lateral margin of apical third area with 1 pair of processes, the ventral surface of process slightly expanded, the apex of process obtuse (Fig. 14H); apical area inverted trapezoidal, lateral margins of subapical area obviously constricted, apical margin with 1 small lateral spine on each side (Fig. 14E). Cerci slender, conical, apices acute. Subgenital plate wider than long, posterior margin slightly arched; styli long, conical, inserted on the posterolateral area of subgenital plate (Fig. 14F).

Female. Posterior margin of eighth abdominal tergite slightly projected; ninth abdominal tergite posteriorly obtusely projected, dorsal surface with longitudinal furrow in the middle; tenth abdominal tergite arched concave on posterior margin (Fig. 15D–E). Epiproct trapezoidal, apical margin almost straight (Fig. 15E). Ovipositor shorter than hind femora, moderately upcurved, dorsal margins smooth, apices acute; apical area of ventral margins with indistinct teeth (Fig. 15F). Lateral margins of subgenital plate narrowing, posterior margin with small spine in the middle (Fig. 15G).

Coloration. Body brown. Terga with black spots.

Discussion. This new species differs from Rhaphidophora spinifera Gorochov, 2013 by: the epiproct of male shorter, apical margin with small spines (Fig. 14E); posterior margin of male subgenital plate slightly arched without median concavity, styli longer (Fig. 14F); posterior margin of female ninth abdominal tergite with median furrow (Fig. 15E), tenth abdominal tergite posteriorly arched, epiproct trapezoidal, posterior margin of female subgenital plate with 1 small median spine (Fig. 15G).

Etymology. We wish to thank Professor Fuming Shi for his great contribution to the Chinese Ensifera.
