Description

Males measure 20–25 mm (0.79–0.98 in) and females 22–29 mm (0.87–1.14 in) in snout–vent length. Dorsum and flanks are coffee-coloured; dorsum has three large blotches. There is a complete, pale oblique lateral stripe. Most individuals also have a ventrolateral stripe that is complete, diffuse, or interrupted.[4][5]

Reproduction

Male call is a series of two or three quickly repeated peeps.[6] Males and females form pairs and defend territories that can be stable over several months. These are defined by deep burrows used as shelter. Fecundity of females is 6–11 oocytes (based on three females), whereas males have been recorded carrying clutches of 9–13 tadpoles.[4]

Habitat and conservation

Hyloxalus sauli occurs in primary and secondary forests at elevations of 200–800 m (660–2,620 ft) above sea level. It lives under leaf-litter near streams and on overhanging banks of permanent streams.[1][4]

Hyloxalus sauli is relatively widespread but uncommon species. It is assessed as being of "least concern", but habitat loss and degradation can be localized threats.[1]

gollark: Have you *even* tried out the amazing/wondrous search?!
gollark: See, isn't this great?!
gollark: Mostly because I never documented its full powers.
gollark: Yes, indeed. You don't even know its full powers.
