New species of narrow-mouthed frog (Amphibia: Anura: Microhylidae; genus Kaloula) from the mountains of Southern Luzon and Polillo Islands, Philippines

We describe a new species of narrow-mouthed frog of the genus Kaloula from the volcanic mountains of southern Luzon Island (Mt. Banahao, Mt. Isarog, and Mt. Mayon) and adjacent Polillo Island, Philippines. On the volcanoes of southern Luzon, the new species is found in habitats ranging from small dr...

Description
Summary:We describe a new species of narrow-mouthed frog of the genus Kaloula from the volcanic mountains of southern Luzon Island (Mt. Banahao, Mt. Isarog, and Mt. Mayon) and adjacent Polillo Island, Philippines. On the volcanoes of southern Luzon, the new species is found in habitats ranging from small dry stream beds to stationary pools of rivers in mid- to upper montane primary forest. On Polillo Is- land, the new species has been found near quiet streams in selectively logged primary forest and second growth near sea level. The new species presumably is allied to Kaloula rigida (a forest species endemic to northern Luzon Island) and to Kaloula picta (a more widespread Philippine endemic that is found in a variety of habitats) as indicated by possession of narrow disks on the digits and by the presence of supernumerary tubercles on the palmar surface of the manus. It differs from these species by its smaller body size, reduction of webbing on toes, absence or extreme reduction of outer metacarpal tubercles, and by characteristics of the advertisement call. Isang ba´gong uriı´n ng palaka´ng kı´tirang-bibig (Amphibia: Anura: Microhylidae; genus Kaloula) mula sa bu´lubundu´kin ng Pulong Luzon at Pulong Polillo, Pilipinas. (Lagom).—Inilalarawan namin ang isang ba´gong uriı´n ng palaka´ng kı´tirang-bibig ng angka´ng Kaloula mula sa mabulka´ng bulu´ bundukin ng katimu´gang Luzon (Bk. Banahao, Bk. Isarog, at Bk. Mayon) at sa mga pulo´ ng Polillo, Pilipinas. Sa mga bulkan ng katimu´gang Luzon, ang bagong uriı´n ay matatagpuan sa mga pa´nirahang abo´t mula sa mga maliliit na patay na sapa´ hanggang sa mga tining na layo´ n ng mga ilog sa may kalagitnaan hanggang sa ilayang gubat o orihinal na tampo´ k-gubat. Ang isang populasyon ay nakilala rin mula sa mga mababang hayon ng mga pa´ nirahang-gubat sa pulo´ ng Polillo. Ano bagong uriı´n ay kaanib ng Kaloula rigida (isang uriı´ng-gubat na taa´l sa Pulong Luzon) at ng Kaloula picta (higit na palasa´ k na uriı´ng ta´al sa Pilipinas at matatagpuan sa mga iba’t-ibang uri ng pa´nirahan) ba´tay sa ipinapakita nitong pag-aangkin ng mga makikitid na disk sa mga daliri at ng kawalan nito ng mga butlig sa sa´latang pa´lad sa kama´y nito´ . Ita ay naiiba sa mga na´banggit na uriı´n dahil sa pangangatawan nitong may kaliitan bawa´s na pa´likpikan sa mga dulong daliri, at sa maraming katangian nito sa usaping taga´l at ispektrum ng kanyang hudya´t-panta´wag
