Diagnosis. Small thickly encrusting Latrunculiidae, with smooth, microscopically hispid surface. Surface usually with volcano­shaped or cylindrical oscules, together with mammiform to crater­shaped areolate porefields. Colour in life and in preservative unknown. The choanosomal skeleton consists of a large­meshed polygonal reticulation formed by wispy tracts of spicules with no spongin reinforcement. The ectosomal skeleton is a tangential layer of megascleres. The surface of the sponge has a distinct palisade of anisodiscorhabds. Megascleres are smooth or polytylote styles 160 µm – 190 µm x 6µm. Microscleres are anisodiscorhabds 40 µm in length (after Burton, unpublished catalogue, BMNH) (Fig. 1A and Table 3), with clearly distinguished basal, median and subsidiary whorls. The sponge (whose habitat and depth range is unknown), has only been recorded from the Cape Verde Islands in the North Atlantic (Fig. 2) (modified from Bocage, 1869). Geographic Distribution. (Fig. 2). Cape Verde Islands. Remarks. The type material of Latrunculia cratera is not available from the Museu Bocage, Lisbon; Bocage's sponge collection was lost after the museum burnt down in 1978. This species has not been recorded since it was first described. Alleged fragments of the type of Latrunculia cratera have since been reported in the Norman and Lervig collections in the BMNH, all of which have been examined and transferred to either the genus Sceptrella (Latrunculiidae) or Sigmosceptrella (Podospongiidae) (see Samaai and Kelly 2002 and Kelly and Samaai 2002 for revision on families) (Table 1). While this species is poorly known, the original description, illustrations (du Bocage 1869) and description of microsclere ontogeny (Dendy 1917), have provided a clear definition of the key characters that define Latrunculia species. : Published as part of Samaai, Toufiek, Gibbons, Mark J. & Kelly, Michelle, 2006, Revision of the genus Latrunculia du Bocage, 1869 Porifera: Demospongiae: Latrunculiidae) with descriptions of new species from New Caledonia and the Northeastern Pacific (, pp. 1-71 in Zootaxa 1127 (1) on page 9, DOI: 10.11646/zootaxa.1127.1.1, http://zenodo.org/record/5057828 : {"references": ["Bocage, J.
