Leptodactylus troglodytes (common names: Pernambuco white-lipped frog, hole-dwelling thin-toed frog, sibilator frog) is a species of frogs in the family Leptodactylidae. It is endemic to northeastern Brazil and occurs from northern Minas Gerais and Bahia to Maranhão, Piauí, Ceará, and Rio Grande do Norte. The specific name, troglodytes, refers to its habit of breeding in underground chambers.
Adult males measure 46–53 mm (1.8–2.1 in) and adult females 45–53 mm (1.8–2.1 in) in snout–vent length. The tympanum is distinct. Males have more acuminate snout than females. Dorsal folds are absent and dorsolateral folds are indistinct or (usually) absent; lateral folds are also absent or interrupted. The belly is uniformly light.
The tadpoles grow to 43 mm (1.7 in) in total length (Gosner stage 36). This species builds foam nests in underground chambers near water. Single tunnel may have multiple chambers. Males are territorial and emit territorial as well as courtship calls, to which the female may reciprocate. Leptodactylus troglodytes is a common species that occurs in dry and moist savanna and agricultural land in the Cerrado... Wikipedia →

Possible
About 20% of wildlife watchers report a Pernambuco White-lipped Frog sighting in João Pessoa on a given day, based on 5 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Pernambuco White-lipped Frog in João Pessoa on a given day, against under 5% in April, July–August and October–January, the lowest months. That is one of João Pessoa's wettest months, with about 230 mm of rain against 20 mm in November.

Across all the parks we cover, that three-hour window holds the most Pernambuco White-lipped Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

GBIF citizen-science records
It is estimated from how often the Pernambuco White-lipped Frog is recorded against all the amphibians logged in João Pessoa (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
