Pararhadinaea

Pararhadinaea is a small genus in the family Pseudoxyrhophiidae, the dominant group of snakes on Madagascar. The genus is represented in our database by a single species, the Madagascar burrowing snake (Pararhadinaea melanogaster). Like most members of its family, it is endemic to Madagascar and belongs to a radiation of snakes that diversified on the island in isolation. These are not boas, pythons, or true vipers; they sit within the broad assemblage of advanced snakes once lumped under the colubrid umbrella, now placed in their own Madagascar-centered family.

Members are small, slender, and built for life in the soil and leaf litter of forested habitats. As a fossorial or semi-fossorial group, they spend much of their time hidden underground or beneath cover, which makes them rarely seen and poorly documented. In general terms you would recognize this kind of snake by its modest size, smooth scales, reduced eyes typical of burrowers, and a cylindrical body suited to pushing through earth rather than climbing or swimming. Coloration in this family tends toward plain browns and darker tones that blend with soil and litter.

Many Pseudoxyrhophiidae are rear-fanged, meaning any venom apparatus sits toward the back of the jaw and is used to subdue small prey such as invertebrates, frogs, lizards, or other small animals depending on the species. For a snake of this size and lifestyle, there is no evidence of danger to humans, and most of the family is considered harmless to people. Even so, no wild snake should be handled, and a venomous or rear-fanged snake should never be treated as safe to handle. If a bite occurs, or if you are unsure what bit you, seek emergency care: in the US call Poison Control at 1-800-222-1222 or contact local emergency services. Because this genus is obscure and poorly studied, treat specific claims about its diet, reproduction, and behavior as inferred from close relatives rather than firmly established.
