A review of Norwegian streptaster-bearing Astrophorida (Porifera: Demospongiae: Tetractinellida), new records and a new species Author Cárdenas, Paco Author Rapp, Hans Tore text Zootaxa 2012 3253 1 52 journal article 10.5281/zenodo.280590 35f6ecad-68d3-44cb-9183-d1c9617c2c57 1175-5326 280590 Genus Thenea Gray, 1867 Diagnosis: Theneidae with tetraxonic megascleres and without cladotyles. Most of the taxonomy concerning Thenea has already been treated elsewhere ( Steenstrup & Tendal 1982 ) so our description will mainly focus on new data. Our study will notably add new records, additional illustrations (external morphology and spicules) and discuss the molecular phylogenetic data now available for those species ( Cárdenas et al . 2011 ).
