ROVARTANI KÖZLEMÉNYEK LIX 1998 pp. 79-101 A review of the Omiamima hanakii group (Coleoptera: Curculionidae) A. Podlussány A review of the Omiamima hanakii group (Coleoptera: Curculionidae) - Two new genera (Bryodaemon gen. n., Humeromima gen. n.) and three new species (Bryodaemon rozneri sp. n., B. kocsirenae sp. n., B. boroveci sp. n.) are described. Omias Hanakii var. montanus Petri, 1912 is elevated to subspecies rank. A key to the species of Bryodaemon gen. n. is given. With 46 figures. INTRODUCTION Species of the genus Omiamima Silfverberg, 1977 are characterized by the following features: surface more or less nitid, glabrous or vested with simple or doubled dorsal hairs; in the latter case the vestiture consisting of shorter recumbent and longer erect hairs; rostrum short and wide, without dorsal curvature, with short scrobes partially visible from above; pronotum glabrous or with longitudinally directed hairs; elytra ovoid or spherical; hind wings absent; femora unarmed; tarsal claws connate basally. According to Dieckmann (1980) there are 25 species of Omiamima in the Palearctic, five of which inhabit Central Europe. All these five are known to occur also in the Carpathian Basin, including the Carpathian Mountains, i. e. Omiamima mollina (Boheman in Schönherr, 1834), O. concinna (Boheman in Schönherr, 1834), O. vindobonensis (Formánek, 1908), O. rufipes Boheman in Schönherr, 1834) and O. hanakii (I. Frivaldszky, 1865). Two further species are mentioned in the present paper: Omiamima brandisi (Apfelbeck, 1903) from Bosnia and O. nitida (Boheman in Schönherr, 1843) from Russia. The biology of the species treated here is largely unknown. The specimens were sifted from moss [Pleurozium schreberi (Willd.)] or leaf litter in the vicinity of mosses in beech or spruce forests in the Carpathian Mountains, 500-1200 m above sea level. If the five Central European species are studied in detail, it can be recognized that Omiamima is an agglomeration of species with different shapes of head and various situations of scrobes. It is merely a dumping ground of species that lack the generic features of the three most closely related genera. Species of Barypeithes Jacquelin du Val, 1854 have the scrobes directed downwards; species of Rhinomias Reitter, 1894 have a dorsally curved rostrum; and species of Omias Germar, 1817 have the pronotal vestiture transversely directed. In Omiamima Silfverberg, 1977 there are species with distinct, erect vestiture as well as seemingly glabrous species with reduced, recumbent hairs. The latter are suggested to split from Omiamima and two new genera are proposed for them. Some
