Description. Female: Body black, with matted dense pubescence. Antennae, apex of tibiae and tarsi red-brown. Head subconical, coarsely punctate. Rostrum 0.7 times as long as pronotum, 2.2 times as long as wide at apex, 2.3 times as long as wide at midlength and 2.4 times as long as wide at base, curved, weakly flattened dorsally, densely punctate; apex subglabrous. Eyes large, linear, 0.3 times as long as wide, not protruding from contour of head, contiguous ventrally, coarsely faceted. Forehead weakly impressed, about 0.9 times as narrow as rostrum base width, densely punctate. Temples about 1.4 times as long as eye length. Antennal scrobes directed to base of rostrum. Antennae inserted before middle of rostrum. Scape long, 4.5 times as long as wide in apex, extends beyond back of eye. Funicle 4-segmented. Antennomere 2 suboval, 1.3 times as long as wide in apex, about 0.2 times as long as and 0.8 times as narrow as scape. Antennomere 3 conical, about 1.4 times as long as wide in apex, 0.8 times as long as and about 0.8 times as narrow as antennomere 2. Antennomeres 4 and 5 wide-conical. Antennomere 4 about 0.6 times as long as wide in apex, about 0.5 times as long as and 1.2 times as wide as antennomere 3. Antennomere 5 0.5 times as long as wide, subequal in length and slightly wider than antennomere 4. Antennal club compact, not truncate, 1.6 times as long as wide, 0.9 times as long as antennomeres 2-5 combined, with tomentose apex. Pronotum campanulate, 1.3 times as long as wide at apex, 1.1 times as long as wide at midlength and 1.2 times as long as wide at pronotal base, with weak pronotal constriction. Pronotal disc weakly convex dorsally, coarsely punctate. Intervals between points smaller than their diameter. Maximum width in middle. Sides almost straight lines in second and third thirds. Scutellum small, subsquare. Elytra narrowed from humeri to apex, at base and at midlength 1.8 times as long as wide, at apical fourth 2.5 times as long as wide, 2.0 times as long as pronotum. Humeri weakly flattened. Elytral striae distinct, about 1.7 times as wide as interstria width. Interstriae convex, carinate, quite narrow. Prosternum punctate, without postocular lobes. Precoxal portion of prosternum 1.4 times as long as procoxal cavity length. Postcoxal portion of prosternum short, 0.5 times as long as procoxal cavity. Procoxal cavities quite narrowly separated. Metepistrnum concealed by elytra. Metaventrite four times as long as length of metacoxa, flattened, coarsely punctate. Ventrites 1 and 2 weakly convex, coarsely punctate. Ventrite 1 subequal to length of metacoxa. Ventrite 2 1.4 times as long as ventrite 1. Ventrites 3 and 4 subequal in length, short, flattened. Ventrite 3 0.3 times as long as ventrite 2. Ventrite 5 4.0 times as long as ventrite 4, coarsely punctate. Procoxae spherical. Metacoxae almost transverse. Femora slightly thickened, without tooth. Tibiae weakly curved, with large uncus. Tarsi long. Tarsomeres 1-3 subconical. Tarsomere 4 square. Tarsomere 5 elongate. Tarsal claws free, divergent. Total body length (without rostrum) 3.0 mm. Length of rostrum 0.6 mm.

Differential diagnosis. The new species differs from Stenommatus ocularis (Konishi, 1963) from Kyushu I., Amami-Oshima, and Okinawa I.) in the carinate elytral intestriae, the body with matted dense pubescence, narrower pronotum, and shorter rostrum.

Etymology. Patronymic. In honor of Dmitry Telnov (Natural History Museum, London, United Kingdom), who studies the biodiversity of New Guinea beetles.

Localisation. New Guinea: Star Mountains.

Remarks. Probably this species was recorded by Zimmerman (1993) for New Guinea.
