Description. Body sub-cylindrical. Head and mouthparts black; basal four antennomeres fulvous, other antennomeres brown. Pronotum fulvous with black spots; a big, black spot at basal pronotum oblong, extended or constricted occasionally, a much smaller spot (sometimes reduced or missing) present on each side. Scutellum black. Elytra fulvous, each elytron with three black markings ( Figs. 2 View FIGURE 2. C A, 12B): one oblong humeral spot; one spot at basal one-third near elytral suture; these two spots barely connected, forming an oblique band; one reduced band at apical one-third (sometimes divided into two isolated spots). Ventral side of body black, propleura fulvous; legs black, tibiae and tarsi reddish-brown.
Head small, vertex convex, surface covered with sparse punctures, shallow wrinkles and a single feeble longitudinal median groove. Frons sparsely pubescent, medially depressed, coarsely and sparsely punctured; clypeus widely incised at anterior margin, with short setae. Labrum slightly incised, clothed with sparse setae; length ratio of maxillary palpomeres 0.4:1.2: 1.1:1.4; length ratio of labial palpomeres 0.3:1.2:1.3; mentum deeply emarginate. Antennae short, extending to middle of pronotum; 1st antennomere oblong, 2nd and 3rd round, 4th feebly angular, 11th ovate, other antennomeres serrate; all antennomeres except 3rd covered with short setae; length ratio of antennomeres 1.0:0.5:0.5:0.5:0.6:0.7:0.7:0.6:0.6:0.7:0.8.
Pronotum transverse, 1.5 times as wide as long, widest at base, convex, narrowly bordered; lateral margins slightly arcuate, covered with dense and fine punctures, especially on posterior angels; anterior angles rectangular, posterior ones obtusely-angled; posterior margin moderately lobed medially. Scutellum triangular, impunctate, base covered with sparse pubescence, apex obtuse, feebly elevated above surface of elytra.
Elytra 1.3 times as long as wide, parallel-sided in first three-fourths, lustrous, very finely punctured. Epipleura present along anterobasal one-third of elytra.
Ventral side of body covered with long slivery pubescence. Legs robust, thickly pubescent, tarsi broad, last tarsomere long, longer than 2nd and 3rd combined together, length ratio of protarsomeres 0.8:0.7:0.6:1.8.
Median lobe with nearly truncate apex ( Fig. 2 View FIGURE 2. C D, 2F), not emarginate, ventral side ( Fig. 2 View FIGURE 2. C F) with lateral tuft of setae at apical one-fifth, slightly convex medially, each side of convex area with a shallow oblong impression in ventral view.
Female. Body more robust than males. Tarsi more slender. Spermatheca ( Fig. 2 View FIGURE 2. C G) medium-sized, spermathecal duct thin, loosely and helically coiled about 20 times, base long and inflated (uncoiled).
Measurement. Length. male: 8.2–9.5 mm, female: 8.6–9.7 mm.
Etymology. The specific epithet is a Latin adjective truncatula (truncated) and refers to the nearly truncated apex of median lobe.
Distribution. China (Xinjiang).
Remarks. Clytra (Clytraria) truncatula sp. nov. is similar to C. (Clytraria) atraphaxidis punctata in the elytral color pattern, but the truncated median lobe apex of the former differs from the emarginate median lobe apex of the latter; also, the last tarsomere of the new species is much longer, longer than the length of 2nd and 3rd tarsomeres together.
