CITES - Not Listed IUCN - Endangered (2020).

philippinensis species group. Redescribed by Hill (1972). Includes paradoxolophus; see Corbet and Hill (1992), Zhang et al. (2018), and Tu et al. (2023). See also Dorst (1954), Eger and Fenton (2003), and Thonglongya (1973). Includes schnitzleri; see Tu et al. (2023). We follow Tu et al. (2023) who found no evidence of subspecific divergence within rex sensu lato. Also see Tu et al's (2023) discussion of Chornelia et al.'s (2022) suggestion that this taxon contains cryptic diversity. Tu et al. (2023) note that rex s.l. is likely Near Threatened under IUCN criteria.
