DIAGNOSIS.—A large species, to 50.2 mm SVL. Pachydactylus acuminatus may be distinguished from all other members of the P. serval/weberi group by the combination of the following characters: nostril rim not strongly inflated, rostral excluded from nostril; supranasals in contact anteriorly; scales on snout and canthus flattened to weakly domed, much larger than those of interorbital and parietal regions, which include tiny granules intermixed with small, weakly-conical tubercles; dorsal scalation highly heterogeneous, with small, oval, weakly to moderately keeled tubercles in 14–18 regular to irregular rows, smallest middorsally and on anterior third of body (approximately 3–5 times size of adjacent granules); thighs and shanks bearing enlarged conical to mucronate tubercles; toes relatively short, toe pads relatively wide (1.5–2.0 times width of proximal part of digit); typically 6 undivided lamellae beneath digit IVof pes; tail to at least 97% SVL, annulate, may be expanded greatly basally in association with fat storage, bearing whorls of small, rounded, very weakly-keeled, well-separated tubercles; adult pattern of yellowish- to pinkish-brown with traces of three wide transverse bands (on nape, trunk anterior to midbody, and sacrum) augmented by irregular brown blotches and spots, some with light centers, between bands, sometimes obscuring banding (see also Visser 1984:48); hatchlings and juveniles with broad, pale (white to grayish), dark-edged bandlumbar region (see also Visser 1984: 49), occasionaly with one or more additional pale bands on trunk.

Distribution: see map in BRANCH et al. 2011.
