The savanna vine snake (Thelotornis capensis), also known commonly, as the southern vine snake, is a species of highly venomous snake in the subfamily Colubrinae of the family Colubridae. There are two recognized subspecies.

Geographic distribution

Thelotornis capensis is found in southern Africa.[2]

Habitat

The preferred natural habitats of Thelotornis capensis are forest, savanna, and shrubland.[1]

Behavior

Thelotornis capensis is diurnal and semi-arboreal.[1]

Description

Thelotornis capensis is slender and has a long tail. The longest museum specimen is a male with a snout-to-vent length (SVL) of 106 cm (42 in), a tail 62 cm (24 in) long, and a combined total length of 168 cm (66 in).[2][3]

Venom

Thelotornis capensis is venomous.[3] Venom is delivered by large grooved teeth at the rear of the upper jaw.[2] German herpetologist Robert Mertens died as the result of being bitten by this species.

Reproduction

Thelotornis capensis is oviparous.[1][2][3] Clutch size is 4–13 eggs.[1] The eggs are elongated and rather small, each measuring on average 36 mm (1.4 in) long and 16 mm (0.63 in) wide.[2]

Subspecies

Two subspecies of Thelotornis capensis are recognized as being valid, including the nominotypical subspecies.[3]

  • Thelotornis capensis capensis A. Smith, 1849
  • Thelotornis capensis oatesi (Günther, 1881)

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Thelotornis.

Etymology

The subspecific name, oatesi, honors British naturalist Frank Oates.[4]
