Mussuranas ( Clelia ) are a genus of the adder . The species Clelia clelia is best described . Although mussuranas are medium to large-sized snakes, they are rarely found in nature. The genre is also rarely represented in collections.

Systematics

The following seven species of this genus are known:

The following species, which used to belong to Clelia , have now been separated into their own genus Mussurana .

Clelia belongs to the tribe Pseudoboini within the subfamily Dipsadinae . According to Vidal et al. the following system:

 Pseudoboini 





Pseudoboa


   

Boiruna


   

Clelia




   

Drepanoides


   

Mussurana




   

Phimophis



   

Oxyrhopus



   

Siphlophis



Accordingly, the species that are more closely related to Drepanoides were moved to the genus Mussurana . The sister genus of Clelia is Boiruna .

features

Juvenile mussuranas have a white collar and are usually reddish with black stripes. They change color as soon as they grow up; most species are then darkly colored. They reach a head-torso length of 57 to 280 centimeters, with Clelia plumbea being the largest species. Females generally grow larger than males. The mating season is probably all year round, but it is not known whether this also applies to species such as C. rustica that occur in the cooler habitats . Clelia are oviparous , i.e. egg-laying. The number of eggs depends on the size of the female; clutch sizes between 4 and 30 eggs have been observed.

distribution

The snakes of the genus Clelia are found mainly in South America . Clelia clelia has the largest range, reaching in the north to Mexico and in the south to Uruguay . Clelia errabunda is endemic and probably extinct on the Antilles island of St. Lucia .
