12. PHYLOGENETIC RELATIONSHIP

12.1 Within genus Calamaria



Fig. 10: Dendogram for 44 Calamariaspecies. [6].



Phylogeny within genus Calamaria remains unresolved

A dendogram for the phenetic relationship within genus Calamaria is however available (Fig. 10)

Footnote Macro

Inger, R. F. & H. Marx, 1965. The systematics and evolution of the Oriental colubrid snakes of the genus Calamaria. Fieldiana Zoology, 49: 1-304.

. This dendogram was developed by Inger & Marx in 1965 based on mean morphological character differences of 44 Calamaria species which have modified teeth. No phylogenetic relationship is implied by this dendogram because it is purely based on morphological similarities.

Despite the increasing popularity of molecular studies, molecular data is still lacking for most Calamariaspecies, including the Pink-headed Reed Snake. More data is required for the construction of a phylogenetic tree for the genus Calamaria.

There are currently no genetic data available for the Pink-headed Reed Snake. Check the National Centre for Biotechnology Information (NCBI) database for more updates.
