Fascaplysinopsis revision. Revision of Fascaplysinopsis reticulata (Hentschel, 1912) (Porifera, Dictyoceratida, Thorectidae) and descriptions of new species and two new thorectid genera.

The present study examines the taxonomy of sponge species with unique chemistry collectively known as Fascaplysinopsis reticulata (Hentschel, 1912). Examination of Hentschel’s original species upon which the genus Fascaplysinopsis Berguist, 1980 was based in conjunction with a comparison with recent Indo-west Pacific collections, using morphological and molecular analysis (ITS and 28s rDNA), revealed extensive variation. Fascaplysinopsis reticulata was found to be a species complex comprising the genus Fascaplysinopsis, as well as two new genera: Skolosachlyos gen. nov. and Rubafasciculus gen. nov. The new species of Fascaplysinopsis described are F. palauensis sp. nov., F. klovos sp. nov. and F. ronquinni sp. nov. The new species of Skolosachlyos gen. nov. described herein are: S. enlutea sp. nov. and S. nida sp. nov. The new species described of Rubafasciculus gen. nov. include: R. cerasus sp. nov., R. manibus sp. nov., and R. apsamma sp. nov.
