Description. Male. Body black, with matted pubescence. Antennae, apex of tibiae and tarsi redbrown. Head subconical. Mandibles small. Rostrum long, subequal in length or slightly longer than pronotum, about 4.1-4.7 times as long as wide at apex, 3.6-4.5 times as long as wide at midlength, 3.1-3.3 times as long as wide at base, evenly curved, sparsely punctate. Apex or apical half of rostrum finely punctate. Eyes large, linear, not protruding from contour of head, linear, contiguous ventrally. Forehead flat, 0.3 times as long as rostrum base width. Antennal scrobes directed ventrally to base of rostrum. Antennae inserted near middle of rostrum. Scape long, 4.0-4.1 times as long as wide in apex, not reaching eye. Funicle 6-segmented. Antennomeres 2-7 subconical. Antennomere 2 1.5 times as long as wide in apex, 0.2 times as long as and 0.6 times as narrow as scape. Antennomere 3 1.2 times as long as wide in apex, 0.8 times as long as and 0.9 times as narrow as antennomere 2. Antennomeres 4 and 5 subequal in length. Antennomere 4 0.6 times as long as wide in apex, 0.6 times as long as and 1.2 times as wide as antennomere 3. Antennomere 5 0.5 times as long as wide, about 1.1 times as wide as antennomere 4. Antennomere 6 0.6 times as long as wide, 1.1 times as long as and about 1.1 times as wide as antennomere 5. Antennomere 7 0.6 times as long as wide, about 1.3 times as long as and 1.2 times as wide as antennomere 6. Antennal club compact, obliquely truncate, 1.5 times as long as wide, about 0.7 times as long as antennomeres 2-7 combined, with tomentose apex. Pronotum campanulate, 1.5 times as long as wide at apex, about 1.1-1.2 times as long as wide at midlength, about 1.2 times as long at pronotal base. Pronotal disk weakly convex dorsally, coarsely punctate, with weak carina in middle. Intervals between points smaller than their diameter. Sides weakly narrowed from apical third towards base. Maximum width before middle. Base of pronotum slightly narrower than base of elytra. Scutellum small, triangular. Elytra almost subparallel, at base 1.6-2.1 times as long as wide, at midlength 1.5-1.6 times as long as wide, at apical fourth 2.3-2.6 times as long as wide, 1.7-2.0 times as long as pronotum. Humeri weakly flattened. Elytral striae distinct. Stria 9 short, fused with stria 10 at level of metacoxae. Interstriae convex, narrow, distinctly narrower than striae, pilose. Prosternum punctate, without postocular lobes. Precoxal portion of prosternum slightly longer than procoxal cavity. Postcoxal portion of prosternum short, about 0.4 times as long as procoxal cavity. Procoxal cavities contiguous. Mesocoxal cavities narrowly separated. Metanepisternum absent. Metaventrite 3.0-3.1 times as long as length of metacoxa, weakly convex, punctate. Abdomen weakly convex ventrally, punctate. Ventrite 1 slightly shorter than length of metacoxa. Ventrite 2 slightly subequal in length to shorter than as long as ventrite 1. Ventrite 3 0.5-0.6 times shorter than ventrite 2. Ventrite 4 slightly shorter than ventrite 3. Ventrite 5 about 2.2-3.3 times as long as ventrite 4, densely punctate. Pygidium impressed in meddle. Procoxae subconical. Mesocoxae spherical, narrowly separated. Metacoxae transverse. Femora slightly thickened, without tooth. Metafemora not extending beyond apex of abdomen. Tibiae weakly curved, with large uncus. Tarsi long. Tarsomeres 1-3 conical, with erect setae ventrally. Tarsomere 5 elongate. Tarsal claws free, divergent. Total body length (without rostrum) 2.7-3.7 mm. Length of rostrum 0.8-1.0 mm.

Female. Rostrum slightly narrower. Andominal ventrites 1 and 2 more convex. Total body length (without rostrum) 2.5-3.0 mm. Length of rostrum 0.9-1.0 mm.

Diagnosis. This new species is very similar to A. griseus from Maluku but differs in the wider pronotum, with slightly rounded sides and uniformly curved rostrum.

Etymology. The species is named in honor of Prof. Jarosіaw Skіodowski (Warsaw).

Distribution. Philippines: Mindanao (fig. 2).
