About Physalaemus albonotatus (Steindachner, 1864)
Taxonomy and Common Name
Physalaemus albonotatus, commonly known as the menwig frog, is a species of frog in the Leptodactylidae family.
Geographic Distribution
Its confirmed distribution includes the Mato Grosso and Mato Grosso do Sul states of Brazil, Paraguay, Chacoan Argentina, and Bolivia.
Habitat
This frog lives on the ground near semi-permanent water bodies, temporary water bodies, or flooded grasslands; flooded grasslands serve as its breeding habitat, and it also breeds in temperate ponds and roadside ditches.
Adaptation and Conservation Status
It adapts very well to human disturbance and is not a threatened species.
Breeding Period
A study conducted in Bodoquena, Mato Grosso do Sul, southwestern Brazil, found that Physalaemus albonotatus is a continuous breeder that reproduces throughout the wet season.
Mating Behavior
Males call to attract females from the margins of ponds and flooded areas, while hiding in vegetation or in small depressions like footprints.
Clutch Size
The mean clutch size for this species is approximately 1500 eggs.
Size and Mass
Females and males are similar in overall size: females have a mean snout–vent length of 30.2 mm (1.19 in), ranging from 26 to 34 mm, and a mean body mass of 2.2 g, while males have a mean snout–vent length of 29.7 mm (1.17 in), ranging from 27 to 32 mm, and a mean body mass of 2.4 g.
Female Fecundity
Ovaries account for approximately 27% of a female's total body mass, and fecundity increases as female body size increases.
