Physalaemus albonotatus

Physalaemus albonotatus is a species of frog in the family Leptodactylidae. It is found in Brazil, Paraguay, Chacoan Argentina and Bolivia.

Habitat

Physalaemus albonotatus occurs on the ground near semi-permanent or temporary water bodies or flooded grasslands, its breeding habitat; it also breeds in temperate ponds and roadside ditches. It adapts very well to human disturbance and is in no way threatened.

Reproduction

A study in Bodoquena found Physalaemus albonotatus to be a continuous breeder, breeding throughout the wet season. Males called for females from the margins of ponds and flooded area, hiding in vegetation or in small depressions such as footprints. Mean clutch size was about 1500 eggs. Females were similar in size to males; females had a mean snout–vent length of and mean body mass of 2.2 g. The same measurements were and 2.4 g for males. Ovaries made about 27% of female body mass; fecundity increased with the female body size.

Taxonomy

The holotype of this species was lost, and given the difficult nature of the Physalaemus cuvieri group and the extremely similar species, it was redescribed in 2023 and given a neotype.
