Club compact, long. Antennomere 9 about 1.1 times as long as wide at apex, about 1.3 times as long as and slightly wider than antennomere 8. Antennomere 10 about 1.5 times as long as wide at apex, 1.6 times as long as and about 1.2 times as wide as antennomere 9. Antennomere 11 2.0 times as long as wide at base, about 1.1 times as long as and about 0.8 times as narrow as antennomere 10. Pronotum companiform, 1.3 times as long as wide at apex, about 0.9 times as long as wide in middle, and about 1.1 times as long as wide at base. Greatest width before middle. Disk densely punctate, weakly convex. Sides rounded. Scutellum small, trapezoidal. Elytra suboval, 1.8 times as long as wide at base, 1.4 times as long as wide in middle, about 1.6 times as long as wide at apex, about 2.6 times as long as pronotum. Humeri smoothed. Greatest width in middle. Interstriae wide, flattened, densely punctate. Striae distinct. Procoxal cavities rounded and contiguous. Pre- and postcoxal portions of prosternum very short. Mesocoxal cavities separated. Metaventrite short, slightly shorter than length of metacoxal cavity. Metanepisterna narrow, punctate. Abdomen weakly convex. Abdominal ventrites 1 and 2 fused, with depression in middle. Ventrite 1 about 0.7 times as long as metacoxal cavity. Ventrite 2 about 1.2 times as long as ventrite 1. Ventrites 3 and 4 quite short, equal in length. Ventrite 3 0.7 times as long as ventrite 2. Ventrite 5 flattened, about 2.1 times as long as ventrite 4. Pygidium hidden by elytra. Legs long. Femora widened. Tibiae weakly biconcave, with apical comb of thickened black setae and small mucro. Tarsi long. Metatarsi not longer than pro- and mesotarsi. Tarsomeres 1-3 with brown thorns around edges. Tarsomeres 1 and 2 conical. Tarsomere 2 shorter than tarsomere 1. Tarsomere 3 bilobed. Claws long and free. Tarsomere 5 elongated. Protarsi: tarsomeres 1−3 flattened, with partially reduced pulvilli on lower surface. Mesotarsi: tarsomeres 1 and 2 without pulvilli on lower surface; tarsomere 3 with almost reduced pulvilli on lower surface. Metatarsi: tarsomeres without pulvilli on lower surface. Total body length (without rostrum) 7.8 mm. Length of rostrum 1.9 mm.

Diagnosis. The new species is close to Eremochorus voruchensis and is distinguished by a scape that does not reach the eye, a slightly curved rostrum (lateral view) and a weaker pointed aedeagus.

97 Etymology. The species is named in honour of the late Boris S. Pavlov-Verevkin (Moscow), who collected the holotype of this species .

Distribution. Tajikistan: Sughd Region.
