This paper reports the diagnostic characters, and some remarks on its systematics and notes on its biology are also provided. Key words: Coleoptera, Erirhininae, Korea, Tanysphyrus (Tanysphyroides) major. Introduction Weevils of the tribe Tanysphyrini in the traditional sense live mostly upon semi-aquatic plants, and their bodies have a water- proof coat (Morimoto & Kojima 1999). The genus Tanysphyrus comprises six species on record in two subgenera, as arranged by Egorov et al. (1996). Keys to the species were provided by Voss (1953) and Egorov et al. (1996). Two species, Tanysphyrus (Tanysphyroides) khancaensis Roelofs and T. (T.) brevipennis Voss, are reported in Korea (Hong et al. 2000). The purpose of the present work is to report the occur- rence of T. (T.) major in the central part of the Korean peninsula, to diagnose its characters and to provide notes on its biology. Systematic account Subfamily Erirhininae Schoenherr, 1825 Tribe Tanysphyrini Gistel, 1856 Genus Tanysphyrus Germar, 1817 Mag. Entomol. 2: 340 (type species: Curculio lemnae Fabricius, 1792). Subgenus Tanysphyroides Egorov, 1996 Key to Insects of Russian Far East 3(3): 431 (type species: Tanysphyrus ussuriensis Egorov, 1996). Tanysphyrus (Tanysphyroides) major Roelofs, 1874 (Korean name: mul-dal-gae-bi-ba-gu-mi [sin-ching]) (Figs 1– 9) Diagnosis. Body length 2.3 –3.0 mm (excluding rostrum); greyish, with stain patterns. The stain patterns were observed by the naked eye. Rostrum evenly arcuate from the base. Antennal funicle slender, first segment oblong-ovate, almost twice as long as broad, third to sixth segments each as long as broad; pronotum broadest in the middle; elytra strongly inclined; male aedeagus slender, with a little less broader apex. Remarks. Tanysphyrus khancaensis was described from Lake Khanka in the Russian Far East, which was distinguished from T. major by Egorov et al. (1996) by the following characters: Tanysphyrus khancaensis: rostrum in both sexes straight from the base to antennal sockets, then inclined anteriad; funicle in male antennae with second segment slender, one-third shorter than first, third to six segments each transverse; pronotum slightly longer than broad, broadest before the middle; elytra weakly inclined posteriorly.
