Species Description: Fuiten, A. M., L. J. Welton, A. C. Diesmos, A. J. Barley, B. Oberheide, M. V. Duya, E. L. B. Rico, and R. M. Brown. 2011. A new species of stream frog (Sanguirana) from the mountains of Luzon Island, Philippines. Herpetologica 67:89-103.
Fuiten et al. (2011) distinguishes Sanguirana from Hylarana on the following characters: toe discs possess circummarginal grooves, the absence of vocal sacs and humeral glands, coarse glandular skin on the posterior of abdomen, and the presence or absence of a elongated nuptial pad on manus II. Fuiten et al. (2011) further differentiate S. aurantipunctata from its congeners, all of which are restricted to the Philippines by the following characters: lack of a dark canthal stripe, white postaxial dermal flanges on the limbs, tuberculate white ventral surface, flanks that transition from green-to-purple, yellow/green dorsum, and the presence of bright orange flower shaped spots on the back. Sanguirana aurantipunctata is intermediate in size relative to other Sanguirana species.
In life, dorsal background color of both sexes is yellow-green. In males the dorsum is speckled evenly with small dark gray-purple or larger orange spots. In females the spots are either purple, small, and semi-circular or orange, large, and flower-shaped. In both sexes, the tympanum is grayish pink and the postrictal tubercles are yellow. Trunk tubercles range from pearl-white to yellowish. The lateral surface of the heads is grayish blue and either lack canthal stripes or have a very faint strip. In both sexes, the ventral surface and limbs range in color from purplish-gray to deep purple. Ventral surface of toes are grey-blue to dark grey. When preserved, the dorsal yellow-green becomes gray-blue. The tympanum becomes a light pinkish gray and the postrictal tubercles become pearl-white. The dorsal surfaces of the fingers and toes become a pale yellow while the ventral surfaces of fingers and toe pads are yellowish-gray and toes are cream with a tinge of blue. Foot webbing is grey. Ventral surfaces are cream and the throat is pearl white (Fuiten et al. 2011).
Sanguirana aurantipunctata is sexually dichromatic, with males exhibiting small dark gray or large orange spots. Females, however, possess strikingly larger, flower-shaped orange spots on the dorsal surface. In addition to spot variation, there is variation on the throats with color ranging from grey to white to yellow. There is also variation in the presence of transverse bars on the arms and legs (Fuiten et al. 2011).
