Phalotris is a genus of snakes of the subfamily Dipsadinae. All species of the genus Phalotris are found in South America.[1] The specific name, mertensi, is in honor of German herpetologist Robert Mertens.[2] The specific name, normanscotti, is in honor of Norman Scott, Jr., in recognition of his contribution to the knowledge of the herpetofauna of Paraguay.[3]
Venom
The venom of this genus was poorly characterized, due to the low amount produced by Colubridae, a more detailed characterization of particularly interesting proteins could only be viable by obtaining recombinant proteins, but there is a report of an accident by a Phalotris, which resulted in headache, local and oral mucosa hemorrhage, edema and renal failure. Another accident report occurred with a 37-year-old biologist, whose symptoms were immediate local pain, bleeding and edema, a few hours later there was headache, systemic hemorrhage, fever, myalgia and dark urine. A study of the venom of Phalotris mertensi showed a myotoxic action 3 times greater than Bothrops jararaca.[4][5]
