New and noteworthy snake species records (Colubridae and Dipsadidae) for the Reserva Natural Laguna Blanca, eastern Paraguay

We update a species list of reptile diversity at the Reserva Natural Laguna Blanca, with four additional species of snakes, Drymarchon corais Boie, 1827, Dipsas cisticeps (Boettger, 1885), Oxyrhopus rhombifer rhombifer Dumeril, Bibron & Dumeril, 1854, and Phimophis guerini (Dumeril, Bibron & Dumeril, 1854). This additional data qualifies San Pedro department as the most diverse department in Paraguay for reptiles. We build upon the already strong case for the reserve, which had its official protection lapse after five years, to be redeclared as a protected area and recognised as an “Important Area for the Conservation of Amphibians and Reptiles”.
