The Common

We examined the impact of climatic fluctuations on the phylogeographic structure of the common slug eating snake (Duberrialutrixlutrix) throughout its distribution in South Africa. The evolutionary history within the taxon was examined using partial DNA sequence data for two mitochondrial genes (ND4 + cytb) in combination with a nuclear locus (SPTBN1). Phylogenetic relationships were investigated for both the combined mtDNA and total evidence DNA sequence data. In addition, population and demographic analyses together with divergence time estimations were conducted on the combined mtDNA data. Topologies derived from the combined mtDNA analyses and the total evidence analyses were congruent and retrieved five statistically well-supported clades, suggesting thatDuberrial.lutrixrepresents a species complex. The five clades were generally allopatric, separated by altitudinal barriers and characterised by the absence of shared mtDNA haplotypes suggesting long term isolation. Divergence time estimations indicate that the diversification within theD.l.lutrixspecies complex occurred during the Plio/Pleistocene as a result of climatic fluctuations and habitat shifts for the species. A taxonomic revision of theD.l.lutrixspecies complex may be required to delineate possible species boundaries.

Cryptogenic Species

Bioeroding sponges of theCliona viridisspecies complex play a large role in carbonate cycling and reef health. In the present study we provide the first record and a description of a Mediterranean lineage ofC. viridis(Schmidt, 1862) in the south-western Atlantic. Specimens were collected in Maricás Archipelago, Rio de Janeiro State in September 2010 by scuba diving at 10–12 m depth and deposited in the Porifera collection of Museu Nacional, Universidade Federal do Rio de Janeiro. Morphologically, the specimens presently examined are very similar to those described in the beta and gamma growth form from the Mediterranean. The Brazilian and Mediterranean specimens share large and irregular papillae over 2 cm in diameter, megasclere tylostyles up to 500 µm long and microsclere spirasters with up to five twists and 34 µm long. A Maximum Likelihood analysis of 28S rDNA ofC. viridis, C. aprica, C. jullieni, C. schmidtiandC. varianswas performed for a genetic identification of the Brazilian specimens. The Brazilian material is phylogenetically closer to the MediterraneanC. viridisthan to the Caribbean and Indian Ocean members of this species complex included in the present analysis. Our results suggest thatC. viridisis a cryptogenic species with a distribution extending from the Mediterranean to the eastern Atlantic and in the SE Brazilian coast or further.
