TYPE LOCALITY AND TYPE SPECIMEN (S).— Zamboanga, Mindanao Id., Philippines. Holotype: BMNH 1946.1.15.41 (original number BMNH 82.11.25.13).

PHILIPPINE DISTRIBUTION (ENDEMIC) (Map 37B [p. 148]).— Basilan, Biliran, Bohol, Camiguin Sur, Dinagat, Leyte, Luzon (Prov.: Cagayan, Isabela), Mindanao (Prov.: Agusan del Sur, Davao, Davao del Sur, Davao Oriental, Misamis Oriental, South Cotabato, Zamboanga del Sur [Zamboanga City]), Samar, Siquijor.

REMARKS.— Malnate and Underwood (1988:85), based largely on body scale characters and dentition, assigned two Philippine species formerly included in the genus Natrix and/or Rhabdophis, to Tropidonophis, i.e., T. dendrophiops, and T. negrosensi s. Although we do not feel comfortable with these assignments and believe that the two nominal species should be reassigned to the now well-established genus Rhabdophis, we hesitate to do so pending a thorough genomic analysis. Also, with respect to the placement of the long enigmatic species “ Natrix barbouri Taylor, 1922 ”, as noted in the Remarks under Rhabdophis barbouri, despite similarities in some features with Tropidonophis, they referred barbouri to Rhabdophis (Malnate and Underwood 1988:195) .

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