Biogeographic Analysis

Brachygasterina Macquart, an endemic South American genus, is revised to include Brachygasterina andina sp. nov. from Ecuador (Pichincha). All six species are redescribed, including B. stuebeli that was recently transferred to this genus. A cladistic analysis was performed including five of the six species of the genus and using Delia platura (Meigen), an anthomyiid fly, and Palpibracus veneris (Bigot) as outgroup taxa. Four most parsimonious cladograms were found, all supporting the monophyly of the genus, as previously stated in the literature. According to the selected cladogram, the phylogenetic relationships of Brachygasterina species are as follows: (D. platura (P. veneris ((B. andina, B. stuebeli) (B. major (B. valdiviensis, B. violaceiventris))))). A cladistic biogeographic analysis of the genus was conducted and is discussed. The pattern revealed by the species of Brachygasterina can be explained by vicariant events involving two lineages of Brachygasterina and the evolution of the Andes.

The evolutionary relationships of the West Indian (W. I.) xenodontine snake assemblage has been considered as either monophyletic or paraphyletic. Allozyme data from protein electrophoresis were used to estimate the phylogeny of the W. I. xenodontine snakes. Forty-two species from 25 genera (mainland and W. I. taxa) were examined. The phylogenetic relationships were estimated using parsimony analyses with successive approximation weighting on the data coded two ways: (1) the allele as the character and (2) the locus as the character. The most parsimonious trees from both coding methods indicated a non-monophyletic W. I. xenodontine assemblage. Three W.I. groups were recovered in both coding methods: (1) Jamaican Arrhyton and Darlingtonia, (2) Uromacer and the Cuban Arrhyton, and (3) Alsophis, Ialtris, and the South American Alsophis elegans. The relationships of Hypsirhynchus, Antillophis and Arrhyton exiguum were unstable. Nomenclatural changes are recommended for Darlingtonia, Arrhyton, Ialtris and Alsophis.
