|Diagnosis||DIAGNOSIS.—Arelatively large species, to 48.5 mm SVL(PEM R 4638). Pachydactylus visseri may be distinguished from all other members of the P. serval/weberigroup by the combination of the following characters: nasal region not inflated; rostral excluded from nostril; supranasals in broad or narrow contact; scales on snout and canthus granular, rounded to oval, flattened to weakly domed, much larger than granular scales of interorbital and parietal regions; small, rounded, conical tubercles, much smaller than snout scales, interspersed among granules of interorbital and parietal regions; dorsal scalation heterogeneous, with moderately large (6–9 times dorsal granules), oval, distinctly keeled arranged in 16–18 regular rows, largest on midflanks; thighs bearing enlarged keeled tubercles; toes relatively short, toe pads relatively narrow; typically five undivided lamellae beneath digit IVof pes; tail to at least 120% of SVL, annulate, bearing whorls of moderately large, pointed, weakly to strongly keeled tubercles; adult pattern a series of distinct, wide, pale (cream to beige) transverse bands separated by thinner dark brown bands. Six bands (rarely seven) anterior to sacrum (one on nape, one across shoulders, four evenly spaced between axilla and hindlimb insertion); tail with strongly contrasting cream and dark brown bands of approximately equal width (Figs. 109–110 in Bauer et al. 2006). Juvenile pattern similar to adult (Fig. 111 in Bauer et al. 2006).|

|Etymology||ETYMOLOGY.—The specific epithet is a patronym honoring John D. Visser (21 May 1938 - 15 May 2012), an important contributor to southern African herpetology who kindly provided several hundred specimens from his personal collection for use in this study. The name is constructed in the masculine genitive. The epithet also reflects the occurrence of the species in the Fish (Vis) River Valley. For an aobituary see BROADLEY & SCOTT_PRENDINI 2012.|
