itrains4days #rarespeciestuesday is here again. Today's rare snake is the Atlantic Sharp Vinesnake - Uromacerina ricardinii (Peracca, 1897). This slender and arboreal snake species is endemic to the rapidly disappearing Atlantic Coastal Forests of Southeastern Brazil. It is rather long, growing past a meter in length, and has an exceptionally long tail. Taxonomists still are uncertain on the snakes phylogenetic position since 1) Barely any tissue data exists of this species and the more obvious 2) because the snake is rarely ever seen. Herpetologists tentatively place this monotypic species in the family Dipsadidae, the family which it seems to be most closely related to. So far, Uromacerina ricardinii's distribution and habitat is patchy, and the decline of its native habitat has not helped in its rarity. It has been recorded as far north as Bahia state on the Atlantic Coast, and as south as Rio Grande de Sul, following the Atlantic Forest. One record that has been confirmed is from Para State, an area far northwest of the previous population near the Amazon. It is possible that this is a disjunct or relict population of this snake, or a continuation of the Atlantic Forest population. A similar (in morphology) snake that is known from two specimens named Cercophis auratus (Schlegel, 1837) has a similar possible distribution pattern. While this snake does not have a specimen count as low as Cercophis auratus, it is still extremely poorly known with less than fifty or so specimens collected. As said before it is semi arboreal to arboreal, probably mimicking vines on trees, possibly like the behavior of the US native Opheodrys aestivus (Linnaeus, 1766). Small frogs and lizards are also the probably prey items. A female collected and maintained in captivity, laid three elongate eggs which successfully hatched. It is likely that as more specimens are found, the more we shall know of this mysterious snake. It ranks up as one of my favorite arboreal snakes as well.
