Note. Originally Heller described P. aurofasciatus and P. aurofasciatus var. dilatisignatus from the Basilan Island, showing on sympatry of both. We observed series of specimens that correspond morphologically to type species from Western Mindanao, Zamboanga province. Therefore, we add this new record to current species distribution range. Sympatrical specimens found in Zamboanga province match in various degree the pattern of both P. aurofasciatus and P. aurofasciatus var. dilatisignatus having the only difference of pattern of elytral spots that vary in size (narrow in P. aurofasciatus and wide in P. aurofasciatus var. dilatisignatus ). Having found no more morphological or geographical difference, we consider P. aurofasciatus var, dilatisignatus as synonym of monotypic P. aurofasciatus .
