[email protected] Abstract The Japanese and Taiwanese species of the genus Nosodendron is revised. The genus is subdivided into two subgenera: Nosodendron and Dendrodipnis. Four species are recognized, including two new species, Nosodendron (D.) ogasawaraense and N. (D.) taiwanense, described in this paper. The larvae of three species, N. (N.) asiaticum, N. (D.) coenosum, and N. (D.) ogasawar- aense, are described. Key words: new species, larvae, distribution, associated plants, filter feeding. Introduction recorded (Háva, 2014), and the adults and larvae of these species had not been reviewed. In the present paper, we The adaptation to aquatic habitats by members of review the Japanese and Taiwanese species of the genus Coleoptera evolved independently in some clades, and Nosodendron, with biological notes and descriptions of the there are various degrees of adaptation (Jäch, 1998). The larval stages. families of water beetles (= water adapted beetles) are known from three suborders: Myxophaga (all families), Adephaga Materials and Methods (mainly Dytiscoidea), and Polyphaga (part of the family in Hydrophiloidea, Byrrhoidea, Scirtoidea, and so on).
