Etymology

edit

The specific name syphax is Greek meaning "sweet new wine" and alludes to the bright red color seen in the groin, belly, and ventral surfaces of the thighs and shanks in some living specimens.[3]

Description

edit

Adult males measure 58–83 mm (2.3–3.3 in) and adult females 71–90 mm (2.8–3.5 in) in snout–vent length. The tympanum is distinct. Neither dorsal folds nor dorsolateral folds are present; lateral folds are also absent or are largely interrupted. Most specimens have a glandular dorsum with muted, tile-like dorsal pattern of darker and lighter browns. Light upper lip stripe is not present. The belly has light to moderate mottling and light gray or brown markings.[3]

The tadpoles grow to 44 mm (1.7 in) in total length (Gosner stage 41).[3]

Habitat and conservation

edit

Leptodactylus syphax occurs in open areas, often rocky outcrops, in rock or termite cavities. The tadpoles develop in standing bodies of water, such as quiet side pools of streams. This species can be common in ideal habitat situations, but not otherwise. Overgrazing, agricultural intensification, and fire might be local threats. Its range overlaps with several protected areas.[1]
