ABSTRACT. Taxonomic status of several species of Cylloceria Schiødte, 1838 (Cylloceriinae), Helictes Haliday, 1837 and Plectiscidea Viereck, 1914 (Orthocentrinae), described by Humala [2002, 2003] have been revised. Lectotypes of four species are designated: Cylloceria tenuicornis Humala 2002 (lectotype female, Russia, Yamalo-Nenets Autonomous Okrug; deposited in ZISP), Helictes carinata Humala, 2003 (lectotype male, Russia, Primorsky Terr.; ZISP), H. karelica Humala, 2003 (lectotype female, Russia, Karelia; ZISP) and Plectiscidea fuscifemur Humala, 2003 (lectotype female, Finland; ZMHU). Helictes carinalis Humala, 2007 is a junior synonym of H. carinata Humala, 2003 (syn.n.); Plectiscidea aquilonia Humala, 2008 is a junior synonym and homonym of P. aquilonia Humala, 2003 (syn.n.); P. fuscifemur Humala, 2008 is a junior synonym and homonym of P. fuscifemur Humala, 2003 (syn.n.). Plectiscidea helleni Humala, 2003 is nomen nudum; P. helleni Humala, 2008 is a valid species. The type of Plectiscidea koponeni Humala, 2003 is lost. Colour photographs of type specimens are given.
