Abstract

We describe a new species of ranid frog from the Hylarana signata complex in Peninsular Malaysia based on morphological and genetic differentiation. The new species can be distinguished from its congeners by the following combination of characters: (1) adult males reaching 37.4-37.6 mm snout-vent length; (2) nuptial pads absent in males; (3) humeral glands in males large; (4) webbing on toes reduced, one phalanx free of web on postaxial side of Toe II and pre-axial side of Toe V; (5) dorsolateral stripe straight, continuous, red to orange in color; (6) middorsal region black, unmarked; (7) flanks black, coloration unstratified; (8) flanks, dorsal surfaces of limbs, and upper lip with large, round, yellow spots; (9) venter grayish-brown, with light spots on throat and light reticulations on ventrum. The new species is phenotypically most similar to Hylarana siberu but differs by having larger, more-dense, and more-rounded spots on the flanks and dorsal side of limbs, larger spots along the entire upper lip, and having light, distinct spots on the throat and light reticulations on the ventrum. We use mitochondrial data to estimate genealogical relationships and genetic divergences between the new species, H. siberu, a related and undescribed Sumatran population, and other members of the H. signata complex. These data unequivocally support the specific recognition of the new taxon and provide insights into its evolutionary relationships.
