Description

Male. Body black, covered with appressed yellowish hairs. Rostrum, head, pronotum and scutellum black. Antennomeres 1-7, femora, tibiae, tarsomeres 1, 2 and 5 yellow-brown. Antennomeres 8-11 and tarsomere 3 brown. Rostrum rather long, 0.9 times as long as pronotum, 2.8 times as long as wide at apex, 3.4 times as long as wide at middle and at base, slightly curved, slightly expanded to apex and weakly flattened. Eyes large, weakly convex, round, finely fused. Forehead flattened, 1.6 times as wide as width of rostrum basally, densely punctate. Temples long, slightly shorter than eye. Vertex convex, punctate. Head slightly narrowed behind eyes. Neck weak, transversely wrinkled. Antennae inserted near middle of rostrum, almost reaching pronotum. Antennomeres 1 and 2 suboval, equal in width. Antennomere 1 2.1 times as long as wide in apex. Antennomere 2 1.6 times as long as wide, 0.8 times as long as antennomere 1. Antennomere 3 long-conical, 2.3 times as long as wide, 1.2 times as long as and 0.8 times as narrow as antennomere 2. Antennomeres 4 and 5 oval, equal in length. Antennomere 4 1.1 times as long as wide, 0.6 times as long as antennomere 3. Antennomere 5 0.9 times as long as wide, 1.1 times as wide as antennomere 4. Antennomere 6 0.9 times as long as wide, 0.9 times as long as and equal in width to antennomere 5. Antennomeres 7 and 8 rounded, equal in length. Antennomere 7 0.7 times as long as wide, 0.9 times as long as and 1.2 times as wide as antennomere 6. Antennomere 8 0.6 times as long as wide, 1.1 times as wide as antennomere 7. Antennal club not compact. Antennomere 9 0.9 times as long as wide, 2.3 times as long as and 1.6 times as narrow as antennomere 8. Antennomere 10 0.9 times as long as wide, slightly shorter and equal in width to antennomere 9. Antennomere 11 1.2 times as long as wide, 1.1 times as long as and 0.8 times as narrow as antennomere 10. Pronotum campanulate, 1.3 times as long as wide at apex, 0.9 times as long as wide in middle and slightly shorter than wide at base, with rounded sides. Disk weakly flattened, densely punctate. Scutellum trapezoid, finely punctate. Elytra 1.6 times as long as wide at base, 1.3 times as long as wide at middle, 1.6 times as long as wide at apical fourth, 2.8 times as long as pronotum. Humeri slightly flattened. Elytral striae distinct. Scutellar striole absent. Stria 9 short. Interstriae flattened, wide, finely punctate. Prosternum finely punctate. Pre- and postcoxal portions of prosternum short. Procoxal cavities contiguous. Metanepisternum about 1.2 times as long as wide, finely punctate. Metaventrite 2.2 times as long as length of metacoxa, weakly convex, punctate. Abdomen convex, punctate. Ventrite 1 subequal in length to length of metacoxa. Ventrite 2 1.1 times as long as ventrite 1. Ventrite 3 0.6 times as long as ventrite 2. Ventrite 4 0.9 times as long as ventrite 3. Ventrite 5 equal in length to ventrite 4. Procoxae large, conical. Metacoxae transverse. Femora weakly thickened. Tibiae almost straight, flattened, with costate dorsal margin, without mucro. Tarsi long. Tarsomere 1 long-conical. Tarsomere 2 wide-conical. Tarsomere 3 bilobed. Tarsomere 5 elongate. Tarsal claws divergent and dentate. Protarsi: tarsomere 1 1.8 times as long as wide at apex; tarsomere 2 1.2 times as long as wide at apex, slightly shorter and 1.4 times as wide as tarsomere 1; tarsomere 3 0.8 times as long as wide at apex, 0.7 times as long as and subequal in width to tarsomere 2; tarsomere 5 4.2 times as long as wide at apex, 1.9 times as long as and 0.4 times as narrow as tarsomere 3. Mesotarsi: tarsomere 1 2.3 times as long as wide at apex; tarsomere 2 about 1.1 times as long as wide at apex, 0.7 times as long as and 1.5 times as wide as tarsomere 1; tarsomere 3 0.9 times as long as wide at apex, equal in length and 1.2 times as wide as tarsomere 2; tarsomere 5 3.9 times as long as wide at apex, 1.8 times as long as and 0.4 times as narrow as tarsomere 3. Metatarsi: tarsomere 1 3.0 times as long as wide at apex; tarsomere 2 1.7 times as long as wide at apex, 0.7 times as long as and 1.2 times as wide as tarsomere 1; tarsomere 3 equal in length and width, 0.7 times as long as and 1.2 times as wide as tarsomere 2; tarsomere 5 4.3 times as long as wide at apex, 2.0 times as long as and 0.5 times as narrow as tarsomere 3. Total body length (without rostrum) 4.1 mm. Length of rostrum 0.6 mm.

Differential diagnosis. The new species differs from Pseudodepasophilus blandulus in the yellow-brown elytra, thicker and shorter rostrum, wide pronotum with more rounded sides, wide elytra, shorter antennae, and form of the sclerites of the endophallus armament.

Etymology. The species is named in honor of Dr. Ariel-Leib-Leonid Friedman ( Israel, Tel Aviv).

Localisation. Yunnan ( Fig. 2 ).
