An update of the catalogue of paraphyletic ‘Rhabditidae’ (Nematoda) after eleven years


  • Walter Sudhaus Institut für Biologie/Zoologie der Freien Universität Berlin



Caenorhabditis, Heterorhabditis, Phasmarhabditis, Psychodorhabditis, gastropod-pathogenic


Eleven years after publication, the catalogue on ‘Rhabditidae’ is herewith continued, presenting for subsequently described species information including synonyms, type locality and type habitat. Of the seven genus taxa proposed since 2011, five were judged to be synonymous, and of the 120 species described as new, 11 were suggested to be synonymous. The 109 new valid species are distributed across 25 genus taxa which each represent a side branch of the phylogenetic tree. Diagnostic features are mentioned for the new genera Auanema and Tokorhabditis. The increase in the number of nominal species mainly concerns Caenorhabditis (40 new species), Oscheius (12 new species) and Pellioditis (15 new species). New species were recruited mainly from India (29), Central and South America (17), Europe (15), Africa (9) and China (7 species). A list of nomina nuda is also given.
