Leptodactylus petersii (common name: Peters' thin-toed frog, in Spanish sapito de Peters, i.e. "Peters' toadlet") is a species of frog in the family Leptodactylidae. [1] [2] It is found widely in the Guianas and the Amazon Basin (Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela). [2] It has been confused with Leptodactylus podicipinus and Leptodactylus wagneri , complicating the interpretation of older records and accounts. [1] [2]

Etymology

The specific name petersii honors Wilhelm Peters, a German zoologist. [3]

Description

Male Leptodactylus petersii measure 27–41 mm (1.1–1.6 in) and females 31–51 mm (1.2–2.0 in) in snout–vent length. [4]

The dorsum ranges from greenish or greyish brown to reddish brown and has irregular dark brown to black markings. There is also a dark, triangular inter-orbital mark. The dorsum bears many spicules and short, laterally oriented glandular ridges. The ventrum smooth and has a variable pattern consisting of white background and extensive grey to black mottling in an anastomotic pattern. The throat is dark grey and has white spots. [5] The tympanum is relatively large; [4] the supratympanic fold is distinct and reaches arm insertion. The iris is bronze to reddish brown. Fingers have absent or only weak lateral fringes, whereas the fringes are extensive on toes, which also have basal webbing. Males have two large spines on their thumbs. [5]

The tadpoles grow to a maximum total length of 21 mm (0.83 in), of which the tail accounts for 60% (Gosner stage 36). [4]

Habitat and conservation

Leptodactylus petersii are found in tropical rainforest, forest edge, open areas, savanna enclaves in the tropical rainforest, and open cerrado formations below 600 m (2,000 ft). [1] This nocturnal frog is usually found on the ground near water. [1] [5] Eggs are laid in a foam nest near water, to which the tadpoles will later move. [5]

This common species occurs in many protected areas and is not considered threatened by the IUCN. [1]

<i>Leptodactylus</i> Genus of amphibians

Leptodactylus is a genus of leptodactylid frogs. It includes the species commonly called ditch frogs or white-lipped frogs. It is very similar to Physalaemus, a close relative, and indeed the 2005 described Leptodactylus lauramiriamae is in some aspects intermediate between them.

Adenomera lutzi is a species of frog in the family Leptodactylidae. It is endemic to Guyana. First described from the upper Potaro River based on specimens collected before 1905, it is now known from a number of sites around the Pakaraima Mountains in west-central Guyana. The specific name lutzi honors Adolfo Lutz, a Brazilian medical entomologist and parasitologist and a pioneer of herpetology. Common names Lutz's tropical bullfrog and Lutz's thin-toed frog have been coined for the species.

Pristimantis croceoinguinis is a species of frog in the family Strabomantidae. It is found in the lowland Amazon rainforest of southern Colombia, eastern Ecuador, and extreme north-eastern Peru, likely also extending into the adjacent Brazil. The specific name croceoinguinis refers to the color of the inguinal spots of this frog. Common name Santa Cecilia robber frog has been proposed for it.

<i>Leptodactylus macrosternum</i> Species of amphibian

Leptodactylus macrosternum is a species of frogs in the family Leptodactylidae. It is found in northern Argentina and adjacent eastern Bolivia, Paraguay, northern Uruguay, and southern and western Brazil. The specific name chaquensis refers to the area of Gran Chaco in Argentina. Common name Cei's white-lipped frog has been coined for it, although this particular species lacks the light upper lip stripe common in the genus.

<i>Leptodactylus colombiensis</i> Species of frog

Leptodactylus colombiensis is a species of frog in the family Leptodactylidae. It is found in the foothills and lower slopes of the Andes in Colombia and westernmost Venezuela (Táchira).

Leptodactylus diedrus is a species of frog in the family Leptodactylidae. Its local name is sapito confuso. It is found in northwestern Amazon Basin in Brazil, Colombia, Venezuela, and Peru. Leptodactylus diedrus are found in rocky habitats in tropical rainforest as well as in flooded forest.

Leptodactylus griseigularis is a species of frogs in the family Leptodactylidae. It is found in the Amazonian slopes of the Andes in Bolivia and Peru.

<i>Leptodactylus leptodactyloides</i> Species of amphibian

Leptodactylus leptodactyloides is a species of frogs in the family Leptodactylidae. Its local name is sapito leptodactilo. It is found in the greater Amazon Basin and the Guianas. Leptodactylus leptodactyloides occurs in a range of habitats: savannas, open areas, forest edges, and secondary and primary lowland forest. Reproduction takes place in temporary waterbodies.

<i>Leptodactylus mystacinus</i> Species of frog

Leptodactylus mystacinus is a species of frog in the family Leptodactylidae. It is found in eastern Bolivia and eastwards to Brazil, Paraguay, and Uruguay and southwards to central Argentina. It is also known as the mustached frog.

Leptodactylus nesiotus is a species of frog in the family Leptodactylidae. It was originally described from Icacos Swamp on the south-western peninsula of Trinidad Island and was for a long time believed to be endemic to the island. However, in 2018 specimens were also reported from Guyana, Suriname, and French Guiana. It is probably the sister taxon of Leptodactylus validus. Indeed, the French Guianan records were first identified as L. validus, and it is possible that also some other L. validus records refer to Leptodactylus nesiotus. It is likely that this species is also found in Venezuela, perhaps even wider in open areas of northern South America.
