Axinectya Hallmann, 1917 : 393 ( Type species: Axinella mariana Ridley & Dendy, 1886 : 480 , by original designation). Definition. Raspailia with echinating rhabdostyles geometrically very different from the usually longer choanosomal styles (the latter without any basal rhabd); extra-axial styles forming a radial skeleton perpendicular to the axis; and well differentiated axial and extra-axial skeletons (the former compressed, the latter plumoreticulate and/or radial) (from Hooper et al. 2008 ).
