Phalotris is a genus of snakes of the subfamily Dipsadinae.
All species of the genus Phalotris are found in South America. [1]
The following 19 species are recognized as being valid. [1]
Nota bene : A binomial authority in parentheses indicates that the species was originally described in a genus other than Phalotris.
The specific name, mertensi, is in honor of German herpetologist Robert Mertens. [3]
The specific name, normanscotti, is in honor of Norman Scott, Jr., in recognition of his contribution to the knowledge of the herpetofauna of Paraguay. [4]
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 . [5] [6]
Micrurus is a genus of venomous coral snakes of the family Elapidae.
Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity however, the different species have very similar needs in terms of temperature and precipitation.
Hognose snake is a common name for several unrelated species of snake with upturned snouts, classified in 2 colubrid snake genera and 1 pseudoxyrhophiid snake genus.
