ON THE HIGHER TAXA OF THE PHYLUM NEMERTEA WITH THE TAXONOMIC REVIEW OF THE SUBCLASS ANOPLA

The phylum Nemertea is subdivided into two classes: Arhynchocoela cl. n. (proboscis and rhynchocoel are absent) and Rhynchocoela Schultze, 1 851 (proboscis and rhynchocoel are presernt). The class Arhynchocoela includes the order Arhynchonemertea ord. n. with the family Arhynchone mertidae fam. n. and the only species Arhynchonemertes axi Riser, 1988 .

(Carinomidae) a nd Heteronemertea (Valenciniidae, Lineidae, Poliopsiidae, Pussylineida e, Gorgonorhynchidae and Panorhynchidae). Six new subfamilies (Oxypole llinae, Zygeupoliinae, Paralineinae, Riseriinae, Aetheorhynchinae and Chilineinae) and three new genera (Protubulanus, Nipponomicrura and He teronemertes) are established.
