Now Sitta frontalis saturatior Hartert, 1902 . See Wells, 2007: 430 , and Harrap, 2008b: 142–143 . LECTOTYPE : AMNH 684086 , adult male, collected on Mt. Tahan , 04.38N , 102.14E (BirdLife International, 2001: 2632 ), 4000 ft , Malaysia , in September 1901 , by John Waterstradt. From the Rothschild Collection. COMMENTS: Hartert did not designate a type in the original description, saying only that his series consisted of two adult specimens, both marked male, collected in September and October 1901 . Later, Hartert (1920a: 440) listed the adult male collected in September as the type, thereby designating it the lectotype . The paralectotype is AMNH 684087 , male, collected on Mt. Tahan in October 1901 . Dickinson (2006: 234) and Dickinson et al. (2006b: 292) considered saturatior a synonym of S. frontalis frontalis , with the caveat that Wells (then in press) considered birds of the Malay Peninsula distinct. Wells (2007: 430) discussed the two subspecies and recognized saturatior ; Harrap (2008b: 142–143) also recognized saturatior for Malay Peninsula birds.
