New southern record of Erythrolamprus reginae (Linnaeus, 1758) (Serpentes: Dipsadidae), a vulnerable species in Argentina

Abstract

I present the first record of the tropical snake Erythrolamprus reginae from Entre Ríos province as the southernmost record from Argentina and South America. This record extends the range of this species by 510 km airline south of known localities in Corrientes province. Geographical distribution in Argentina and Paraguay is provided. This record confirms the presence of E. reginae in seasonally flooded gallery forest bordering the Uruguay River, a biogeographical corridor for tropical biota invading temperate latitudes.
