Preliminary revision of the genus Sparedrus (Coleoptera: Oedemeridae) from eastern and southeastern Asia
Species of the genus Sparedrus Megerle, 1821 in DEJEAN (1821) from eastern and southeastern Asia are revised, illustrated and keyed. Three new species are described and illustrated: Sparedrus karenorum sp. nov. (N Thailand), S. malickyi sp. nov. (N Thailand) and S. chiangmaiensis sp. nov. (N Thailand). The following new combinations are proposed: Sparedrus atricolor (Pic, 1935) comb. nov., S. subserratus (Gressitt, 1939) comb. nov., S. latipennis (Pic, 1923) comb. nov., S. angustatus (Pic, 1923) comb. nov., all transfered from Sparedropsis Heyden, 1886, in HEYDEN & KRAATZ (1886). Genus Polacus Sasaji, 1985, syn. nov. is synonymised with Sparedrus. New name, S. sasajii nom. nov., is established for S. longicornis (Sasaji, 1985), secondary homonym of S. longicornis (Iablokoff-Khnzorian, 1970).
