Description

Body red-brown, glabrous.

Male. Rostrum 0.9 times as long as pronotum, subcylindrical, 3.1 times as long as wide at apex, 3.9 times as long as wide in middle, 3.4 times as long as wide at base, weakly curved, widened at apical third, with three indistinct longitudinal carinas, densely punctate. Apex of rostrum with two branches of setae directed anteriorly. Mandibles large, with curved outer edge. Antennal scrobes directed to base of rostrum, visible at base dorsally. Eyes quite large, quite coarsely-faceted, not protruding from contour of head, located laterally. Forehead flattened, densely punctate, barely narrower than width of rostrum basally. Temples shorter than eye, punctate. Vertex weakly convex, densely punctate. Head spherical, widened behind eyes. Antennae inserted in apical third of rostrum. Scape long, 8.4 times as long as wide at apex, not reaching eye. Antennomeres 2-11 with quite long setae. Antennomere 2 long-conical, 2.5 times as long as wide at apex, 0.3 times as long as and 0.9 times as narrow as scape. Antennomeres 3-5 conical. Antennomere 3 1.7 times as long as wide at apex, 0.5 times as long as and 0.8 times as narrow as antennomere 2. Antennomere 4 1.5 times as long as wide at apex, 0.9 times as long as and equal in width to antennomere 3. Antennomere 5 1.1 times as long as wide at apex, 0.9 times as long as and 1.2 times as wide as antennomere 4. Antennomeres 6- 7 wide-conical. Antennomere 6 1.8 times as long as wide at apex, 0.9 times as long as and 1.1 times as wide as antennomere 5. Antennomere 7 equal in length and width, 1.1 times as long as and equal in width to antennomere 6. Antennomere 8 rounded, about 1.1 times as long as wide, 1.1 times as long as and 1.05 times as wide as antennomere 7. Antennal club compact, 2.0 times as long as wide in middle, 0.5 times as long as antennomeres 2-8 combined. Antennomere 9 0.7 times as long as wide, 1.1 times as long as and 1.7 times as wide as antennomere 8. Antennomere 10 0.6 times as long as wide, 0.8 times as long as and equal in width to antennomere 9. Antennomere 11 0.8 times as long as wide, 1.3 times as long as and 0.9 times as narrow as antennomere 10. Pronotum almost campanulate, 1.4 times as long as wide at apex, 0.9 times as long as wide in middle, 0.8 times as long as wide at base, with rounded sides. Maximal wide before base. Disk weakly convex, finely punctate. Distances between punctations much longer than their diameter. Scutellum very small, indistinct. Elytra almost rounded, 1.5 times as long as wide at base, subequal to wide at middle, 1.6 times as long as wide at apical fourth, 1.9 times as long as pronotum. Humeri absent. Elytral striae weak. Stria 9 short merges with stria 10 near level of metacoxa. Interstriae wide, flat, about 5.0-6.0 times as wide as elytral stria, sparsely punctate and finely transverse-rugose. Prosternum densely punctate, with rostral channel and with weak postocular lobes. Pre- and postcoxal portions of prosternum equal in length. Precoxal portion 0.3 times as long as length of procoxal cavity. Procoxal cavities contiguous. Metanepisternum 6.4 times as long as wide in middle, sparsely punctate. Metaventrite short, 0.5 times as long as length of metacoxal cavity, weakly concav, densely punctate. Abdomen densely punctate. Ventrites 1 and 2 concav in middle. Abdominal ventrite 1 0.9 times as long as metacoxal length. Ventrite 2 1.1 times as long as ventrite 1. Ventrites 3-5 flattened. Ventrite 3 0.5 times as long as ventrite 2. Ventrite 4 0.8 times as long as ventrite 3. Ventrite 5 3.0 times as long as ventrite 4, without anal setae. Legs long, with setae. Procoxae large, conical, coarsely punctate.
