Hydrops martii (Wagler, 1824) (Serpentes, Dipsadidae): first record in Amapá state, northern Brazil

Abstract

Hydrops martii is a poorly known water snake of the tribe Hydropsini, which has been extensively found across northern South America. In this study, we present the first record in Amapá, based on a single specimen from the municipality of Macapá (0.0333, -51.0666), in the tropical moist broad-leafed forests of northern Brazil. This record extends the species range ca 195 km north from its nearest known record, on Marajó Island, in Pará, in the same ecoregion.
