With the exception of some basal branches within Clade 19 Clades 21, 22, and 24 and within “xenodontines” Clades 25, 29, 34these clades are generally well-supported, as measured by bootstrap and Bremer support Fig.

The latter is nested within Clade 58 as the more derived terminal. Within that clade, Uromacer Clade 61 and a clade containing Cuban species of Arrhyton Clade 63 are successive alsophi groups to Clade 64, which contains all remaining West Indian alsophiines Alsophis, Darlingtonia, Antillophis, Ialtris, Jamaican species of Arrhyton, and Hypsirhynchus. Molecular systematics and evolution of Regina and the thamnophiine snakes.

The monophyly of the Elapoidea is currently supported exclusively by molecular data and further inquiry on its composition is needed. Hemipenial body much longer than the lbes more than twice the lengthwith the aulcate side of the hemipenial body covered with two parallel rows of enlarged body calyces on most or all its surface.

This approach simultaneously estimates the nucleotide alignment and the phylogenetic tree based on the algorithm described by Sankoff This clade is supported by a single putative morphological synapomorphy: In general, these are clades that appear repeatedly in different studies directed at the appropriate level, an example being Caenophidia.

Alsophis elegans Tschudi, Elegand Presence of ontogenetic changes in color pattern; juveniles with a brick red color, a black longitudinal vertebral band, and an uniformly creamish venter. The Animal Diversity Web is an educational resource written largely by and for college students.

We thus describe the new genus Mussurana to accommodate Clelia bicolor and two closely related species previously assigned to Clelia Zaher, b. Thus, further revisions on that issue may be eleggans.

Intra-viperid relationships have been studied by numerous workers and we have little to add to these other works given our deliberate de-emphasis on this group other than its placement broadly within Caenophidia.

After that, we retro-translated to DNA and aligned the sequences for this group over the aligned matrix using the default parameters in Clustal X. Chromatograms were checked and, when necessary, were manually edited using Bioedit version 7.
