Subspecies 
Common NamesE: Sierra Madre Blind Snake 
SynonymMalayotyphlops denrorum WYNN, DIESMOS & BROWN 2016 
DistributionPhilippine Islnds (Luzon)

Type locality: Luzon island, Isabela Province, Municipality of San Mariano, Sierra Madre Mountain Range, Apaya Creek area, Barangay Dibuluan, Sitio Apaya (17.029° N, 122.1928° E; datum: WGS 84; Fig. 1 in WYNN et al. 2016).  
Reproductionoviparous (manual imputation, fide Zimin et al. 2022) 
TypesHolotype: PNM 9813 (field collector number ACD 2084; formerly KU 328594), collected 25 February 2005 by Arvin C. Diesmos and Rogelio V. Sison. 
DiagnosisDiagnosis: External characters indicate the new species to be a member of the genus Malayotyphlops as restricted above. Malayotyphlops denrorum can be distinguished from M. ruficaudus and M. canlaonensis by its lower number of longitudinal scale rows (usually 30 in M. ruficaudus and M. canlaonensis behind the head, 26 in M. denrorum), its lighter, more diffusely-edged dorsal stripe, and more extensive pigmentation on the tail. The extreme reduction in size of its third and fourth supralabials, and relatively large eyes, distinguish Malayotyphlops denrorum from species in the T. ruficaudus Group that have 28 or 26 anterior scale rows posterior to the head (M. castanotus, M. collaris, M. hypogius, M. luzonensis, and M. ruber). A key for distinguishing Philippine species of the genus Malayotyphlops is presented in Appendix 2 in WYNN et al. 2016. 
Comment 
EtymologyNamed after “the dedicated management and staff of the Philippine Department of Environment and Natural Resources (DENR). We greatly appreciate the partnership and support of the DENR (in particular the Biodiversity Management Bureau, formerly the Protected Areas and Wildlife Bureau) and commend the agency, its dedicated staff, and leadership for their steadfast efforts towards protection and sustainable management of the natural resources of the Philippines.” (WYNN et al. 2016).
