Adult Leptodactylus savagei are large, the head is as wide as long or usually wider than long, and the hind limbs are moderate in length (Table 1; Heyer and Thompson (2000) provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are not visible externally. Sexually active males have hypertrophied forearms, usually 1 large black spine on each thumb, rarely with 1 large spine and a prepollical bump, and a pair of black chest spines. A pair of entire dorsolateral folds extend anteriorly from at least one_half to full distance from eye to groin, the dorsolateral folds are rarely interrupted. Flank folds (diverging from the supratympanic fold at the uppermost posterior portion of the tympanum and extending as far as the lower flank at mid_body level) range from entire (often) to only a dark spot/wart (rarely) in the area where the fold would be between the tympanum and shoulder. Lateral folds are not distinguishable. The toe tips are rounded and either barely wider than or of equal width as the toes immediately behind the tips. The toes have weak to noticeable lateral ridges and either lack any web or (usually) have vestigial webbing between toes I-II-III or I-II-III-IV. Metamorphic and slightly larger juveniles lack webbing and either have very weak lateral ridges or lack them. The upper shank surfaces almost always have some texture, including a shagreen and/or small black or white tubercles. The outer surface of the tarsus may either be smooth or with a shagreen or small black or white tubercles. The sole of the foot is typically smooth, lacking texture.
