Abstract

Dictyostelids are a monophyletic group of sorocarp-forming social amoebae in the major eukaryotic division Amoebozoa. Members of this taxon, which is made up of almost 200 described species, are common in terrestrial soils globally. Still, the alpha diversity is not well known in many areas, and new species are frequently recovered. The highest species richness is found in the tropics. Here, five new species are described from soil samples collected in Madagascar. These species—Cavenderia basinodulosa, C. canoespora, Heterostelium radiatum, H. versatile, and Raperostelium stabile—are described based on both morphological characteristics and molecular data, with sequence data from the rDNA small subunit (SSU). The five new species are... (More)

Dictyostelids are a monophyletic group of sorocarp-forming social amoebae in the major eukaryotic division Amoebozoa. Members of this taxon, which is made up of almost 200 described species, are common in terrestrial soils globally. Still, the alpha diversity is not well known in many areas, and new species are frequently recovered. The highest species richness is found in the tropics. Here, five new species are described from soil samples collected in Madagascar. These species—Cavenderia basinodulosa, C. canoespora, Heterostelium radiatum, H. versatile, and Raperostelium stabile—are described based on both morphological characteristics and molecular data, with sequence data from the rDNA small subunit (SSU). The five new species are morphologically disparate, ranging from relatively small, robust taxa such as R. stabile to taxa with variable morphologies such as the larger H. radiatum and H. versatile and the yellow-tinted and irregularly branched species C. canoespora and C. basinulosa. These new species, together with earlier work where 13 other species were described from the island, suggest that there is a range of genetically diverse and highly morphologically variable dictyostelid taxa occurring on Madagascar, suggesting biogeographic patterns even within these very small organisms.

Funding Information: Field work in Madagascar in 2009 was supported by a grant (DEB-0316284) from the National Science Foundation to the University of Arkansas. It was carried out under the project “Survey for Eumycetozoans in Madagascar” and the permit numbers 087/09/MEFT/SG/DGEF/DSAP/SLRSE and 088/09/MEFT/SG/DGEF/DSAP/SLRSE. Field work in Madagascar in 2009 was possible with the assistance provided by the staff at the Madagascar Institut pour la Conservation des Ecosystemes Tropicaux (MICET).
