Two New Species of Malayotyphlops from the Northern Philippines, with Redescriptions of Malayotyphlops luzonensis (Taylor) and Malayotyphlops ruber (Boettger)
As a first step toward making sense of an infamously enigmatic and taxonomically problematic group of Philippine blind snakes, we redescribe Malayotyphlops luzonensis (Taylor, 1919) and Malayotyphlops ruber (Boettger, 1897) and clarify their taxonomic status with respect to each other and to additional phenotypically similar taxa. We also describe two other new species of Malayotyphlops from the Sierra Madre Mountain Range of northern Luzon Island, each on the basis of a single specimen. We suspect that species diversity of the typhlopid fauna of the Philippines is severely underestimated, with progress towards a comprehensive understanding of this group most hampered by a lack of sufficient comparative material available in biodiversity repositories.Abstract

Dorsal (top) and left lateral (bottom) views of the head of the holotype of Malayotyphlops ruber (SMF 16616). Only the free edges of the scale plates are shown with the exception of the gland rows underlying the lateral edges of the rostral plate; color pattern is not depicted because of the faded state of this specimen.

A map of Luzon Island (shaded dark gray, inset), northern Philippines. The type localities of new and redescribed species are indicated: (1) M. andyi, Barangay Nassiping, Municipality of Gattaran, Cagayan Province; (2) M. denrorum, Barangay Dibuluan, Municipality of San Mariano, Isabela Province; (3) M. luzonensis, Mt. Maquiling, Municipality of Los Baños, Laguna Province; and (4) M. ruber, Samar Island (arrow, inset). Star = capital city of Manila.
