TYPE LOCALITY AND TYPE SPECIMEN (S).— Philippines. Holotype: BMNH 1946.1 .1.99.

PHILIPPINE DISTRIBUTION (ENDEMIC) ( Map 31b [p. 142]).— Cebu, Masbate, Negros (Prov.: Negros Occidental, Negros Oriental), Panay (Prov.: Aklan). Localities needing confirmation include: Calamianes Ids., Luzon (Prov.: Aurora, Bataan, Nucva Ecija), Mindanao or Dinagat Ids.

REMARKS.— This small, distinctive species of Pseudorabdion , once thought to be rare, has been found with increasing frequency on Negros Island. The species has been reported from other islands, Luzon ( Casto de Elera [1895]), Mindanao or Dinagat (type of Typhlogeophis brevis Günther ), and the Calamianes (specimen in the collection of CAS), but these records need confirmation.

Also, see Leviton and Brown (1959:487 et seq.) for a discusion of the status of Typhlogeophis brevis Günther , which was based on a single specimen said to have come from Mindanao or Dinagat islands, and was distinguished from P. oxycephalum in having its eyes “hidden” beneath the ocular scale.

Pseudorabdion oxycephalum , endemic to the Philippine Islands, does not appear to be close to Sulawesian or Bornean species. Indeed, its closest relative, P. montanum , is at present known only from the highlands on Negros Island.

CONSERVATION STATUS [IUCN].— Least Concern [2016] ver. 3.1.
