Reproduction in the Madagascar leaf‐nosed snake, langaha madagascariensis (Serpentes: Colubridae: Pseudoxyrhophiinae)
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: KennethL. Krysko --- University of Florida, USAAspects of reproduction including courtship behaviour, ovipositioning, egg characteristics, and hatchling descriptions are documented for the Madagascar leaf‐nosed snake (Langaha madagascariensis). Courtship behaviour is described from laboratory settings and takes place in vegetation above ground. Oviposition occurred at night time... -

Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Luca Luiselli --- Centre of Environmental Studies “Demetra”, and F.I.Z.V., Italy GodfreyC. Akani --- Rivers State University of Science and Technology, Nigeria FrancescoM. Angelici --- Centre of Environmental Studies “Demetra”, and F.I.Z.V., Edoardo Politano --- Centre of Environmental Studies “Demetra”, and F.I.Z.V., Linda Ude --- Centre of Environmental Studies “Demetra”, and F.I.Z.V., SundayM. Wariboko --- Rivers State University of Science and Technology, NigeriaA total of 332 specimens (59 subadults, 131 males and 142 females) of the semiaquatic colubrid Afronatrix anoscopus were collected in southern Nigeria to study their dietary preferences. The adult male to female sex‐ratio (0.92) was not significantly different from... -
Feeding behaviour of the Madagascar leaf‐nosed snake, Langaha madagascariensis (Serpentes: Colubridae: Pseudoxyrhophiinae), with an alternative hypothesis for its bizarre head structure
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: KennethL. Krysko --- University of Florida, USAFeeding behaviour of the Madagascar leaf‐nosed snake (Langaha madagascariensis) is described and an alternative use for its unusual nasal appendage is hypothesized. Langaha madagascariensis employs a sit‐and‐wait foraging strategy and stalking prey is initiated once a snake is conscious of... -
Aprosdoketophis andreonei, a new genus and species of snake from Somalia (Serpentes: Colubridae: Boiginae)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Van Wallach --- , USA Benedetto Lanza --- Museo di Storia Naturale dell'Università di Firenze, Sezione di Zoologia “La Specola”, Italy Annamaria Nistri --- Museo di Storia Naturale dell'Università di Firenze, Sezione di Zoologia “La Specola”, ItalyAn aglyphous colubroid snake representing a new genus and species is described from Somalia. It is a terrestrial form that inhabits xerophytic woodlands. A comparison with both African and extralimital genera indicates that its relationships lie with the opisthoglyph Boiginae...
