Abstract: 

Atyid freshwater shrimps are globally distributed and form an important
part of freshwater ecosystems, particularly in the tropics and
subtropics. Despite their widespread distribution and ecological
importance, their phylogenetic relationships are largely unresolved.
Here we present the first comprehensive molecular phylogeny of the
Atyidae investigating the evolutionary relationships among 32 of the 42
genera using mitochondrial and nuclear markers. Our data indicate that
the established classification of the Atyidae is in need of substantial
taxonomic revision at all taxonomic levels. We suggest a new
suprageneric systematization of atyids and discuss problematic issues at
the generic level, particularly in the most speciose genus, Caridina.
Molecular clock based divergence time estimates for atyids vary widely,
but invariably support the assumption that atyids are an ancient
freshwater lineage with an origin in the mid-Cretaceous at the very
latest. Atyid distribution patterns are the result of instances of both
long-distance dispersal and vicariance, depending largely on the
reproductive mode of taxa. From an evolutionary perspective, the high
frequency of independent origin of both a complete (landlocked)
freshwater life cycle and a cave-dwelling mode of life is remarkable and
unparalleled among crustaceans.
