Type species: Clinophaestus robustus Storozhenko, sp. nov., here designated.

Description. Body robust, moderate in size (Figs. 35, 36). Head not exserted above the pronotum in lateral view (Fig. 25). Antennae 11-segmented, 2.5–2.8 times longer than fore femora; two apical segments narrow; outer side of 5th–9th segments apically triangularly pointed (Fig. 24). Antennal bases situated below the lower margin of eyes (Fig. 27). Eyes more or less globular, slightly elevated above the vertex in lateral view (Fig. 25). Fastigium of vertex in dorsal view triangular; median fastigial carinula obsolete, lateral carinulae well defined (Fig. 26). Fastigium of vertex and frontal ridge in lateral view forming distinct notch (Fig. 25). Width of frontal ridge near the base of antennae 1.7–2.0 times less than width of 1st antennal segment. Apical segments of maxillary palps slightly widened. Pronotum in dorsal view with broadly rounded anterior margin (Fig. 23); posterior process of pronotum almost reaching the apex of abdomen (Figs. 25, 38). Disc of pronotum densely granulated; posterior process broadly triangular with bifurcate apex (Fig. 23). Median carina of pronotum in lateral view low, almost straight (Fig. 22); lateral carinae in prozona distinct, smooth; prozona 1.3–1.5 times as long as wide; posterior angles of lateral lobes of pronotum turned downward, obliquely truncate at apex (Fig. 23). Hind margin of the lateral lobes of pronotum with the lower sinus only, the tegminal (upper) sinus absent (Fig. 22). Tegmina and hind wings absent. Fore femora 2.9–3.1 times, mid femora 2.5–2.7 times as long as wide. Hind femora oviform, stout, 1.9–2.1 times as long as wide (Fig. 28). Male subgenital plate short, with broadly rounded apex (Fig. 32). Female subgenital plate 1.1–1.2 times as long as wide, with triangularly pointed posterior margin (Fig. 34). Valves of ovipositor broad.
