Hyper-cryptic marine meiofauna: Species complexes in Nemertodermatida.
PLoS ONE 9(9): e107688. doi:10.1371/journal.pone.0107688

Abstract / Notes

"Nemertodermatida are microscopically small, benthic marine worms. Specimens of two nominal species, Sterreria
psammicola and Nemertinoides elongatus from 33 locations worldwide were sequenced for three molecular markers.
Species delimitation and validation was done using gene trees, haplotype networks and multilocus Bayesian
analysis. We found 20 supported species of which nine: Nemertinoides glandulosum n.sp., N. wolfgangi n.sp.,
Sterreria boucheti n.sp., S. lundini n.sp., S. martindalei n.sp., S. monolithes n.sp., S. papuensis n.sp., S.
variabilis n.sp. and S. ylvae n.sp., are described including nucleotide-based diagnoses. The distribution
patterns indicate transoceanic dispersal in some of the species. Sympatric species were found in many cases.
The high level of cryptic diversity in this meiofauna group implies that marine diversity may be higher than
previously estimated. "
