Family Leptodactylidae Werner, 1896

Leptodactylus bolivianus Boulenger, 1898 is distributed in the western and central portions of the Amazon Basin in Bolivia, Brazil, Colombia, Peru and Venezuela ( Heyer & de Sá 2011), whereas Leptodactylus guianensis Heyer & de Sá, 2011 is distributed across the Guiana Shield. These two species are morphologically quite similar to each other and, before the description of L. guianensis in 2011, it was commonly confused with L. bolivianus in the literature ( Heyer & de Sá 2011). We consider the record of L. cf. bolivianus from Lima (2006b) to be L. guianensis . Gazoni et al. (2021) recently revisited the systematics of the group of L. melanonotus using an integrative approach. One of the taxonomic results was the revalidation of L. intermedius , previously a junior synonym of Leptodactylus petersii Steindachner, 1864 . Besides L. petersii , there are records of two other species of the group of L. melanonotus in Amapá: L. wagneri (Lima 2006) and Leptodactylus podicipinus Cope, 1862 (PereiraJúnior et al. 2013; Araújo & Costa 2015; Lima 2018; Costa-Campos & Freire 2019). All records previously associated with L. podicipinus in Amapá should be assigned to L. intermedius . Leptodactylus wagneri is distributed in western Amazonia and the records in eastern Amazonia correspond either to L. intermedius (see Gazoni et al. 2021) or to unnamed species, treated here as Leptodactylus sp. , endemic to the Eastern Guiana Shield (Carvalho et al. in press). Leptodactylus leptodactyloides (Andersson, 1945) is widely distributed in Amazonia but reported in Amapá for the first time in this study. The species was confirmed to occur at one location (Comunidade Ariri), within the municipality of Macapá, based on DNA-barcoded individuals (Carvalho et al. in press).
