Abstract / Notes

Six new species of the suborder Proseriata are described: Monocelis rotulifer sp. nov., Heteromonocelis
australiensis gen. nov. sp. nov., Archimonocelis rohdei sp. nov., Bulbotoplana hearnsi sp. nov., Cirroplana
mansi gen. nov. sp. nov. (Cirroplaninae subfam. nov.) and Lauraplana arrawarrensis gen. nov. sp. nov. Three
species of uncertain status (due to sexual immaturity) are also described - Archotoplaninae species 1,
Cirroplaninae species 1 and Parotoplaninae species 1. All of these species inhabit sandy beaches of warm
temperate New South Wales, Australia. Heteromonocelis gen. nov., Monocelidinae, is established on the basis
of stylet bearing accessory organs. The establishment of the subfamily, Cirroplaninae subfam. nov., is based
on the presence of a cirrus in lieu of a sclerotized stylet and spines in an Otoplanidae specimen. It
includes only the genus Cirroplana gen. nov. The genus Lauraplana gen. nov. is established based on the
possession of a separate male and female gonopore. Three species belonging to the family Otoplanidae are
described (Bulbotoplana hearnsi sp. nov., Cirroplana mansi gen. nov. sp. nov. (Cirroplaninae subfam. nov.)
and Lauraplana arrawarrensis gen. nov. sp. nov.), representing the first description of this family in
Australia. Recommendations are given for future taxonomic sampling.
