A revision of the higher taxonomy of the Afrotropical freshwater crabs (Decapoda: Brachyura) with a discussion of their biogeography

The higher taxonomy of the 20 known genera of Afrotropical freshwater crabs is revised to reflect the evolutionary relationships revealed by the consensus of a series of recent morphological and

Phylogeny of the freshwater crabs of the Western Ghats (Brachyura, Gecarcinucidae)

There is an urgent need for continued faunistic studies to assess the true diversity of gecarcinucid crabs on the Indian subcontinent, to fully understand the basal phylogenetic relationships within the freshwater crab family Gecarc inucidae, and to evaluate the conservation threat status and biogeography of the montane freshwater crabs of the Western Ghats.

Evolutionary history of true crabs (Crustacea: Decapoda: Brachyura) and the origin of freshwater crabs.

This work reconstructs the most comprehensive phylogeny of Brachyura to date using sequence data of six nuclear protein-coding genes and two mitochondrial rRNA genes from more than 140 species belonging to 58 families, and confirms that the "Podotremata," are paraphyletic.

Multi-locus Phylogeny of the Afrotropical Freshwater Crab Fauna

—Phylogenetic reconstruction, divergence time estimations and ancestral range estimation were undertaken for 66% of the Afrotropical freshwater crab fauna (Potamonautidae) based on four partial DNA

Multilocus Phylogeny of the Afrotropical Freshwater Crab Fauna Reveals Historical Drainage Connectivity and Transoceanic Dispersal Since the Eocene.

The present study represents the most comprehensive taxonomic sampling of any freshwater crab family globally, and explores the impact of paleodrainage interconnectivity on cladogenesis among freshwater crabs.

When Indian crabs were not yet Asian - biogeographic evidence for Eocene proximity of India and Southeast Asia

It is postulated that the India and Southeast Asia were close enough for exchange of freshwater organisms during the Middle Eocene, before the final Indian-Eurasian collision.

New lineages within the Malagasy freshwater crab fauna: Agora n. gen. for Thelphusa goudoti H. Milne Edwards, 1853, and a phytotelmic new species of Malagasya Cumberlidge & Sternberg, 2002 (Brachyura: Potamonautidae: Deckeniinae)

New molecular and morphological analyses of the relationships of 77 specimens of potamonautid freshwater crabs collected from all parts of Madagascar support the monophyly of the island’s freshwater

Insular species of Afrotropical freshwater crabs (Crustacea: Decapoda: Brachyura: Potamonautidae and Potamidae) with special reference to Madagascar and the Seychelles

The evolutionary relationships between island and mainland faunas of the 24 species of insular freshwater crabs in the Afrotropical region are reviewed in the light of phylogenetic studies. Twenty



Molecular phylogeny of hyperoliid treefrogs : biogeographic origin of Malagasy and Seychellean taxa and re-analysis of familial paraphyly

Treefrogs of the family Hyperoliidae are distributed in Africa, Madagascar and the Seychelles. In this study, their phylogeny was studied using sequences of fragments of the mitochondrial 16S and 12S

A cladistic analysis of Platythelphusa A. Milne-Edwards, 1887, from Lake Tanganyika, East Africa (Decapoda: Potamoidea: Platythelphusidae) with comments on the phylogenetic position of the group

The phylogenetic relationships of the freshwater crab genus Platythelphusa were investigated by means of a cladistic analysis using morphological characters and the evidence supports an hypothesis for the evolution of this family from freshwater crab ancestors.

Phylogeny and biogeography of exacum (gentianaceae): a disjunctive distribution in the Indian ocean basin resulted from long distance dispersal and extensive radiation.

The molecular dating analysis demonstrates that the radiation is too recent to be associated with the Gondwanan continental breakup, and Ancestral area reconstruction suggests that Exacum originated in Madagascar, and divergence dating suggests its origin was not before the Eocene.

Notes on the position of the true freshwater crabs within the brachyrhynchan Eubrachyura (Crustacea: Decapoda: Brachyura)

A large scale homoplasy identified here may nullify any reliable hypothesis of brachyrhynchan groupings at this stage and is broadly congruent with a previous cladistic analysis of selected eubrachyuran familial groundpatterns.

On the taxonomic status and biogeography of the Isolapotamidae Bott, 1970 (Decapoda, Brachyura)

Recent investigations of Asian freshwater crabs of the superfamily Potamoidea Ortmann, 1896 use the Potamidae Ortmann, 1896 as the only valid family, although three families have been described from

New frog family from India reveals an ancient biogeographical link with the Seychelles

A burrowing frog from India that is noticeably distinct from known taxa in all anuran families is found and recognized as a new family because of its very distinct morphology and an inferred origin that is earlier than several neobatrachian families.

Evolution of Afrotropical freshwater crab lineages obscured by morphological convergence.

Distribution patterns of the Malagasy freshwater crabs (Crustacea: Decapoda: Brachyura)

Overlaps in the distribution patterns of taxa indicate that there are centres of endemism (biodiversity hotspots) for freshwater crabs in the north-west lowland coastal region of Antsiranana Province in northern Madagascar.

Chameleon radiation by oceanic dispersal

Support for a phylogeny and area cladogram that does not fit a simple vicariant history for chameleons is shown, using molecular and morphological evidence for 52 chameleon taxa.

Skelosophusa ( Crustacea , Decapoda , Brachyura ) , a New Genus of Potamonautid Freshwater Crab from Madagascar , with Descriptions of Two New Species

  • Biology
  • 2008
A new genus, Skelosophusa, is established for Madagapotamon gollhardi BOTT, 1965, and two new species, S. eumeces and S. prolixa, are described, characterized by the shape of the male abdomen, form of the anterolateral margin andshape of the carapace.
