Abstract

We describe a new species of Pulchrana from the island of Sumatra, in western Indonesia. Pulchrana
fantastica, new species, is currently only known from Aceh and Sumatera Utara provinces. It is related to P. siberu
and P. centropeninsularis as inferred from morphological similarity and phylogenetic relationships, estimated from
DNA sequences. It can be diagnosed by the following unique combination of characters: (1) SVL adult males
40.32–45.19 mm; (2) males have large humeral glands on the anteroventral surface of brachium, nuptial pads absent;
(3) dorsal skin finely granular to granulated, with or without asperities at the tip of granules; (4) webbing formula:
I(1 ― 1–11/2)II(1/2 ― 2)III(1 ― 2–21/3)IV(2–21/3 ― 1)V; (5) straight dorsolateral stripes, thin, continuous,
anteriorly confluent at snout, posteriorly interconnected by a series of spots; (6) middorsum in adults black with
light medial line or combination of spots and line, black without marking in juveniles; (7) dense cream or yellow
to orange spots on flanks, and dorsal side of limbs, spots non-uniform in shape; (8) venter greyish or brown, with
small light dots on throat and chest, sometimes reaching abdomen; (9) iris background black, lower part with dense
orange stippling, upper region with orange reticulation with gold in the middle, pupil encircled with solid orangegolden
line; (10) upper and lower lip grey or brown with cream or yellow spots. We also report the presence of P.
centropeninsularis from Sumatra; a species previously known only from a single locality in the Malay Peninsula;
and discuss the biogeographic implications of this significant range extension.
