Genus/Species

 

Various African and Arabian Elapids of minor medical importance

Species

  • 1. Aspidelaps lubricus
  • 2. Aspidelaps scutatus
  • 3. Elapsoidea boulengeri
  • 4. Elapsoidea broadleyi
  • 5. Elapsoidea chelazziorum
  • 6. Elapsoidea guentherii
  • 7. Elapsoidea laticincta
  • 8. Elapsoidea loveridgei
  • 9. Elapsoidea nigra
  • 10. Elapsoidea semiannulata
  • 11. Elapsoidea sundevallii
  • 12. Elapsoidea trapei
  • 13. Hormoroselaps dorsalis
  • 14. Hormoroselaps lacteus
  • 15. Pseudohaje goldii
  • 16. Pseudohaje nigra
  • 17. Walterinnesia aegyptia
  • 18. Walterinnesia morgani

 

  • The former genus Boulengerina is now assigned to the genus Naja (N. annulata and N. christyi, Wüster et al. 2007).
  • Former Paranaja multifasciata is now assigned to group of true cobras: Naja multifasciata (Wüster et al. 2007).
  • Hormoroselaps spp. = formerly Elaps spp. The taxonomic status of Hormoroselaps spp. is unclear. Some authors classify them as Aparallactinae, a subfamily of the Colubridae

Biology

  1. Aspidelaps spp.: Active at twilight and at night, burrowing species. Live in arid zones such as savannas and semi-deserts. Length up to 80 cm. Short head, wide, shovel-like snout with an enlarged rostral scale (see Morphological key). Markings consist of bands or spots. When threatened they raise their upper body and spread their neck slightly.
  2. Boulengerina spp (now Naja sp.).: Semi-aquatic snakes, in or close to still water and rivers. Length up to 2.4 m. In appearance like cobras, when threatened they spread their necks as cobras do (see Fig.4.57, Naja sp.). Considered harmless.
  3. Elapsoidea spp.: Nocturnal. Live in arid areas. Length up to 1 m. Frequently banded markings.
  4. Hormoroselaps spp.: Conspicuously coloured snakes that mainly live underground. Often in termite mounds. Length 30–60 cm. Very unwilling to bite.
  5. Paranaja multifasciata (now Naja multifasciata): Rare, burrowing species, with relatively long venom fangs. Stout body, length up to 60 cm.
  6. Pseudohaje spp.: Forest-dwelling, arboreal snakes. May also live on the ground or in water. Short head with conspicuously large eyes. Length up to 2 m or more.
  7. Walterinnesia spp.: Nocturnal, native to desert areas. Often found there in oases and gardens. Length up to more than 1 m. Colouring dark or shiny black. During the day they are not at all aggressive when threatened, and try to hide their head under the coils of their own body.
