Characters distinguishing Brachymeles isangdaliri from all nonpentadactyl, limbed species of Brachymeles are summarized in Tables 3 and 4. Additionally, B. isangdaliri can be distin- guished from other species in the B. bonitae Complex (B. bonitae, B. mapalonggaon, B. tridactylus) by having unidactyl limbs (vs. polydactyl or digitless limbs; Table 4). Brachymeles isangdaliri can be distinguished from all limbless species of Brachymeles by having limbs and from all pentadactyl species of Brachymeles by having unidactyl limbs.
