Paraleucilla Dendy 1892

Abstract

Genus Paraleucilla Dendy, 1892 “ Amphoriscidae with leuconoid organization. The thick wall is divided into two regions. The outer region is supported by the skeleton which remains essentially inarticulated, with the apical actines of cortical tetractines pointed inwards, and a layer of triactines and/or tetractines with the unpaired actine pointed outwards. The inner region of the choanoskeleton is intercalated between the original subatrial skeleton and the atrial one, and it is supported by large triactines and/or tetractines, that are scattered in disarray, and whose form is similar to the spicules found in the outer layer of the choanoskeleton, or inside the atrial skeleton. Because the original subatrial layer still remains in the outer part of the choanosome, facing the cortical tetractines, there are no typical subatrial spicules adjacent to the atrial skeleton” (Borojevic et al. 2002).Published as part of Cavalcanti, Fernanda F., Menegola, Carla & Lanna, Emilio, 2014, Three new species of the genus Paraleucilla Dendy, 1892 (Porifera, Calcarea) from the coast of Bahia State, Northeastern Brazil, pp. 537-554 in Zootaxa 3764 (5) on page 539, DOI: 10.11646/zootaxa.3764.5.3, http://zenodo.org/record/22494
