Abstract

A new material on the Indo-Malayan genera Peracca Griffini, 1897 and Oxylakis Redtenbacher, 1891 are examined. The feminine gender for the names of these genera as well as for some other but derivative generic and subgeneric names (generic names Amblylakis Redtenbacher, 1891, Odontolakis Redtenbacher, 1891, Paroxylakis Ingrisch, 1998, Bispinolakis Ingrisch, 1998, Depressacca Ingrisch, 1998 and Viriacca Ingrisch, 1998; subgeneric names Ocellakis Gorochov, 2013, Spinolakis subgen. nov., Sumatracca Gorochov, 2013 and Robustacca Ingrisch, 2020) is more definitely designed, and the necessary corrections of some species names are made. The composition of the genus Peracca is briefly discussed, and P. (Robustacca) setosa Ingrisch, 1998, comb. nov. is transferred from the subgenus Odontoconus Fritze et Carl, 1908 to the subgenus Robustacca. The subgeneric composition of the genus Oxylakis is expanded to four subgenera: Oxylakis s. str., Indolakis Gorochov, 2013, Ocellakis Gorochov, 2013 and Spinolakis subgen. nov. The key for subgenera of the genus Oxylakis is given. The following new species and subspecies are described and illustrated: Peracca (Peracca) simplex sp. nov. from Aceh Province (Sumatra) of Indonesia, Oxylakis (Spinolakis) spinosa sp. nov. from Sabah State (Borneo) of Malaysia and O. (Oxylakis) singaporensis aceh subsp. nov. from Aceh Province (Sumatra) of Indonesia.
