[Herpetology • 2018] Cornufer exedrus • A New Miniature Melanesian Forest Frog (Ceratobatrachidae: Cornufer) from New Britain Island, Constituting the First Record of the Subgenus Batrachylodes from Outside of the Solomon Archipelago ---ScRaBBlE

Abstract

We describe a new species of Cornufer, subgenus Batrachylodes, from high-elevation forests of New Britain Island in the Bismarck Archipelago of Eastern Melanesia. The new species, Cornufer exedrus sp. nov., is a biogeographically disjunct member of the Batrachylodes clade, representing the first record of the subgenus from outside of the Solomon Archipelago. The new species is a small terrestrial form from dense, closed-canopy forests above 1500 meters elevation in the Nakanai Mountains of eastern New Britain. It differs from its closest relatives, the other members of the subgenus Batrachylodes, on the basis of its minute body size, degree of digital disc expansion, reduced subdigital tuberculation, color pattern, and other traits related to its small size. We also provide a description of the new species’ simple advertisement call. The diversity of ceratobatrachid frogs of the Bismarck Archipelago is most likely still underestimated despite several recent surveys. Our understanding of evolutionary trends and species boundaries in the subgenus Batrachylodes currently is hampered by lack of genetic samples and call recordings corresponding to voucher specimens of the endemic species of Bougainville Island.

[Herpetology • 2015] Platymantis quezoni • A New Species of Limestone Karst inhabiting Forest Frog, Genus Platymantis (Ceratobatrachidae: subgenus Lupacolus) from southern Luzon Island, Philippines ---ScRaBBlE

Platymantis (Lupacolus) quezoni

Brown, de Layola, Lorenzo, Diesmos & Diesmos, 2015

DOI: 10.11646/zootaxa.4048.2.3

Abstract

We describe a new species of limestone karst dwelling forest frog of the genus Platymantis from the Quezon Protected Landscape in southeastern Luzon Island, Philippines. We assign Platymantis quezoni, sp. nov., to the diverse assemblage of terrestrial species in the Platymantis dorsalis Group, subgenus Lupacolus on the basis of its body size and proportions, only slightly expanded terminal discs of the fingers and toes, and its terrestrial microhabitat. The new species is distinguished from these and all other Philippine congeners by features of its external morphology, its restriction to a distinctive limestone karst microhabitat, and its advertisement call, which is unique among frogs of the family Ceratobatrachidae. Several distinguishing morphological characters include its moderate body size (22.1–33.9 mm SVL for 16 adult males and 32.4–39.7 mm SVL for five adult females), slightly expanded terminal discs of the fingers and toes, smooth skin with limited dermal tuberculation, and a dorsal color pattern of mottled tan to dark brown with black blotches. The new species is the sixth Philippine Platymantis known to occur exclusively on limestone karst substrates (previously known karst-obligate species include: P. bayani, P. biak, P. insulatus, P. paengi, and P. speleaus). Recently accelerated discovery of limestone karst anurans across the Philippines suggests that numerous additional species may await discovery on the hundreds of scattered karst formations throughout the archipelago. This possibility suggests that a major conservation priority in coming years will be to study, characterize, describe, and preserve the endemic species supported by this patchy, unique and imperiled type of forest ecosystem in the Philippines.

(A) limestone bolder where the holotype (PNM 9817) was recorded and collected; (B) appearance of habitat in late afternoon (~16:30). Note darkened caves and crevices beneath limestone over-hangs from where P. quezoni initiate vocalizations in the late afternoons (16:30–17:30 hr) from concealed perches inside crevices and small caves.

Distribution. Platymantis quezoni is known only from the type locality but may be more wide spread in scattered karst outcrops of northern portions of the Bicol Peninsula (Restificar et al. 2006; MGB 2010), especially on limestone karst formations in the nearby Bondoc Peninsula (Fig. 1).

Etymology. The specific epithet is a patronym in the genitive singular, honoring Manuel Luis Molina Quezon. Quezon served as president of the Commonwealth of the Philippines during the American colonial period from 1935 through the conclusion of the Second World War. An exemplary statesman, he led the struggle for Philippine independence from American rule.
Suggested common name: Quezon Limestone Forest Frog.
