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.

Colletotrichum Gigasporum

A new endophytic species of Colletotrichum was isolated from an endangered orchid species, Cattleya jongheana in the Parque Estadual da Serra Negra, from the state of Minas Gerais, Brazil. It is described and illustrated as Colletotrichum serranegrense sp. nov. in this study. Morphology and multi-locus phylogenetic analyses based on combined ITS, ACT, TUB2 and CHS-1 sequence data revealed that these isolates were in the Colletotrichum gigasporum species complex and confirmed differences in this compared to other species in this genus.
