TYPE MATERIAL. Holotype – ♂, Vietnam: Lao Cai Province, Yên Bái, VI.2023, local collector ( ISEA).

DESCRIPTION. MALE. Body length (without rostrum) 7.7 mm. Rostrum length 1.2 mm. Body brown, covered with short appressed white hairs. Head conical. Mandibles large. Rostrum conical, quite short, almost straight, about 0.6 times as long as pronotum, 2.1 times as long as wide at apex, about 1.9 times as long as wide in middle and 1.5 times as long as wide at base, densely punctate. Eyes large, transversely oval, almost not protruding from contour of head. Forehead flattened, densely punctate, about 0.5 times as narrow as rostrum base width. Temples shorter than eye, rugose-punctate. Antennae long, inserted near middle of rostrum. First antennomere long, weakly curved, about 4.3 times as long as wide at apex, reaching eye. Second and thirst antennomeres long-conical. Second antennomere 2.0 times as long as wide at apex, about 0.3 times as long as and about 0.7 times as narrow as scape. Third-fifth antennomeres of same width. Third antennomere about 1.3 times as long as wide at apex, 0.6 times as long as and 0.9 times as narrow as second antennomere. Fourth-fifth antennomeres conical. Fourth antennomere about 1.1 times as long as wide at apex, slightly shorter than third antennomere.

Fifth antennomere equal to fourth antennomere. Sixth-eighth antennomeres wide-conical. Sixth antennomere about 0.8 times as long as wide at apex, slightly shorter and wider than fifth antennomere. Seventh antennomere about 0.6 times as long as wide at apex, slightly shorter and about 1.3 times as wide as sixth antennomere. Eighth antennomere about 0.4 times as long as wide at apex, of same length and about 1.7 times as wide as seventh antennomere. Antennal club compact, with fused segments, about 0.7 times as long as second-eighth antennomeres combined, weakly pointed. Ninth antennomere about 0.6 times as long as wide at apex, 2.0 times as long as and about 1.2 times as wide as eighth antennomere. Tenth antennomere about 0.7 times as long as wide at apex, slightly longer and wider than ninth antennomere. Eleventh antennomere slightly longer than at base, 1.5 times as long as and slightly narrower than tenth antennomere. Pronotum almost bell-shaped, about 1.3 times as long as wide at apex, slightly longer than wide in middle and about 1.1 times as long as wide at base. Disk weakly convex, densely granulate. Sides almost straight in basal half. Scutellar shield semi-oval. Elytra about 2.2 times as long as wide at base and at apical fourth, about 1.7 times as long as wide in middle, about 2.4 times as long as pronotum. Elytral base not projecting over pronotum base. Humeri slightly flattened. Elytral striae distinct. Ninth striae full. Interstriae flat, wide, finely granulate. Prosternum punctate, with distinct prosternal canal before procoxae. Pre- and postcoxal portions of prosternum short. Precoxal portion about 0.6 times as long as length of procoxal cavity. Postcoxal portion about 0.4 times as long as procoxal portion. Procoxal cavities narrowly separated. Mesocoxal cavities separated. Mesosternal process convex in middle. Metanepisternum very narrow. Metaventrite weakly convex, punctate, about 2.9 times as long as length of metacoxal cavity. Metacoxal cavities widely separated. Abdomen ventrally convex, densely punctate. First and second ventrites fused, equal in length. First ventrite about 1.5 times as long as length of metacoxal cavity. Third ventrite 0.7 times as long as second ventrite. Fourth ventrite slightly narrower than third ventrite. Fifth ventrite about 1.4 times as long as fourth ventrite. Procoxae large, conical. Metacoxae transverse. Femora thickened and flattened, with tooth. Tibiae almost straight, flattened, with large uncus and two groups of setae. Metatibiae with outer setose fringe of tarsal groove strongly sinuate. Tarsi long. First tarsomere long-conical. Second tarsomere conical. Third tarsomere bilobed. Fifth tarsomere elongated. Tarsal claws divergent and appendiculate.

COMPARISION. The new species differs from other species in the genus by its conical rostrum. It can be distinguished from Carcilia major Voss, 1953 from Vietnam, by its smaller body size, shorter second and third antennomeres, and its convex mesosternal process.

DISTRIBUTION. North Vietnam (Lao Cai Province).

ETYMOLOGY. The species is named in honour of Dr Sergey Yu. Storozhenko (Vladivostok, Russia).
