Two Asian genera are diagnosed and their nomenclature is revised: Pleuronota Kraatz (= Macronotiola Mikšić, syn. nov.) and Macronotops nov. (= Pleuronota sensu Mikšić). Key frameworks for both genera and checklists of the known species are given. Pleuronota alleni sp. nov. (Borneo) is described and illustrated. Some new records are given. The following new combinations had to be made. To Pleuronota: aenea (Gestro), elongata (Gory & Percheron), longiuscula (Moser), monticola (Gestro), rufosquamosa (Fairmaire), setosa setosa (Moser), setosa imuganica (Mikšić) (all from Macronotiola), patricia (Gory & Percheron) (from Macronota) ; to Macronotops: fulvoguttata (Fairmaire), fulvopilosa (Fairmaire), nigropubescens (Mikšić), ovaliceps (Arrow), sexmaculata (Kraatz), vuilleti vuilleti (Bourgoin), vuilleti olivaceofusca (Bourgoin) (all from Pleuronota).
