Type material: Holotype, male ( ISEA), INDONESIA: N Moluccas, Bacan Isl. , SE slopes of Mt. Sibela, 5 km SE of Makian vill., 500-750 m, 2-12.V.2008, St. Jakl.
Description. Male: Body black, glabrous. Antennae, tarsi and uncus red-brown. Head nearly conical. Rostrum subcylindrical, weakly curved, about 0.8 times as long as pronotum, 2.4 times as long as wide at apex, about 2.5 times as long as wide in middle, about 2.9 times as long as wide at base, densely and quite coarsely punctate, with middle ventral carina. Rostral apex smooth. Eyes large, coarsely faceted, not protruding from contour of head, linear, narrowly separated beneath. Forehead flattened, about 0.6 times as narrow as rostrum base width, punctate. Temples short, punctate. Antennal scrobes directed ventrally to base of rostrum. Antennae short, inserted near middle of rostrum, reaching pronotum. First antennomere elongate conical, about 4.3 times as long as wide at apex, nearly reaching eyes. Second antennomere suboval, about 1.4 times as long as wide at apex, about 0.3 times as long as and 0.9 times as narrow as first antennomere. Third antennomere conical, equal in length and width, 0.6 times as long as and about 0.9 times as narrow as second antennomere. Fourth and fifth antennomeres wide-conical. Fourth antennomere 0.5 times as long as wide at apex, about 0.7 times as long as and about 1.3 times as wide as third antennomere. Fifth antennomere about 0.4 times as long as wide at apex, subequal in length and about 1.1 times as wide as fourth antennomere. Antennal club obliquely truncate, apically tomentose, 1.7 times as long as wide in middle, equal to second-fifth antennomeres combined. Pronotum nearly bell-shaped, about 1.6 times as long as wide at apex, equal to wide in middle and slightly longer than wide at base. Disk weakly flattened, quite coarsely and densely punctate. Sides weakly curved. Scutellum small, narrow, immersed. Elytra suboval, 2.0 times as long as pronotum, 1.5 times as long as wide at base and in middle, about 2.6 times as long as wide at apical fourth. Humeri flattened. Elytral striae distinct. Ninth striae striae merge with striae 10 near metacoxa. Interstriae weak convex, with row of points, distinctly wider than striae. Interstriae 5 widened at apex. Precoxal portion of prosternum long, equal to procoxal cavity. Postcoxal portion of prosternum short, about 0.3 times as long as precoxal portion. Procoxal cavities contiguous. Metaventrite weakly convex, punctate, about 1.8 times as long as metacoxal cavity. Abdomen convex, finely punctate. First and second ventrites fused. First ventrite about 0.6 times as long as metacoxal cavity. Second ventrite about 1.4 times as long as first ventrites. Third and fourth ventrites equal in length. Third ventrite 0.5 times as long as second ventrite. Fifth ventrite 1.4 times as long as fourth ventrite. Procoxae spherical. Femora weakly thickened, densely punctate. Femora nearly straight, with lateral carinae, uncinate. Tarsi quite long. First - third tarsomeres conical, with erect setae ventrally. Second tarsomere shorter than first tarsomere. Third tarsomere slightly longer than first tarsomere. Fifth tarsomere elongate. Tarsal claws free, divergent. Total body length (without rostrum) 4.1 mm. Length of rostrum 1.0 mm.
Differential diagnosis. The new species differs from D. telnovi Legalov , sp. nov. in the wider, laterally weakly rounded pronotum with the more finely punctured pronotal disc, the stronger widened interstria 5 at apex, the smaller punctures in elytral striae, the wider elytral interstriae and the longer and thinner rostrum.
Etymology. From the Latin ‘insular’.
Localisation. North Moluccas, Bacan Islands.
