Description of Caenorhabditis auriculariae n.sp. (Nematoda: Rhabditida) from fruiting bodies of Auricularia polytricha

摘要

A new Caenorhabditis species collected from fruiting bodies of Auricularia polytricha is described and illustrated. C. auriculariae n. sp. is characterized by the metarhabdion with a bifid flap-like tooth. The caudal papilla 8 bent dorsally and anteriorly bifid brim-like structure on the precloacal lip are also unique to C. auriculariae n. sp. These are considered to be autapomorphic characters for this nwe species. This new species has been obtained also from rotting parts of wood and maintained on bacterial plates of Asparagine-mannitol agar.
