Abstract

ABSTRACT:We review the Philippine frogs of the genus Leptobrachuim. All previous treatments have referred Philippine populations to L. hasseltii, a species we restrict to Java and Bali, Indonesia. We use external morphology, body proportions, color pattern, advertisement calls, and phylogenetic analysis of molecular sequence data to show that Philippine populations of Leptobrachium represent three distinct and formerly unrecognized evolutionary lineages, and we describe each (populations on Mindoro, Palawan, and Mindanao Island groups) as new species. Our findings accentuate the degree to which the biodiversity of Philippine amphibians is currently underestimated and in need of comprehensive review with new and varied types of data.LAGOM: Pinagbalik aralan namin ang mga palaka sa Pilipinas mula sa genus Leptobrachium. Ang nakaraang mga palathala ay tumutukoy sa populasyon ng L. hasseltii, ang uri ng palaka na aming tinakda lamang sa Java at Bali, Indonesia. Ginamit namin ang panglabas na morpolohiya, proporsiyon ng pangangatawan, kulay disenyo, pantawag pansin, at phylogenetic na pagsusuri ng molekular na pagkakasunod-sunod ng datos upang maipakita na ang populasyon sa Pilipinas ng Leptobrachium ay kumakatawan sa tatlong natatangi at dating hindi pa nakilalang ebolusyonaryong lipi. Inilalarawan din naming ang bawat isa (populasyon sa Mindoro, Palawan, at mga grupo ng isla sa Mindanao) na bagong uri ng palaka. Ang aming natuklasan ay nagpapatingkad sa antas kung saan ang biodibersidad ng amphibians sa Pilipinas sa kasalukuyan ay may mababang pagtatantya at nangangailangan ng malawakang pagbabalik-aral ng mga bago at iba’t ibang uri ng datos.
