CLATHRINA SINUSARABICA View in CoL SP. NOV.
Original identification: Clathrina coriacea ( Montagu, 1818)
Etymology: From the type locality.
Type locality: Agig Harbour , Egypt, Red Sea .
Type: BMNH 1912.2 .1.1 (holotype /alcohol). Agig Harbour, Red Sea. C. Crossland Collection (8.1 m) .
Colour: Holotype when preserved is beige.
Description: Cormus not massive, spread on a flat rock, formed of tubes of variable sizes, which are irregular and loosely anastomosed ( Fig. 37A View Figure 37 ). There is one large, pre-eminent tube that forms the osculum. Cells with granules were not observed. The skeleton has no special organization, comprising equiangular and equiradiate triactines ( Fig. 37B View Figure 37 ). Actines are conical, becoming very thin at the distal part. They are also undulated near the tip and very sharp.
Remarks: C. sinusarabica sp. nov. is similar to many other clathrinas with triactines with regard to external features, such as the anastomosis of the cormus and the absence of water-collecting tubes. However, it can be distinguished by the shape and size of its spicules: it can be differentiated from C. aurea , C. cribrata , C. cylindractina , C. heronensis , C. wistariensis and C. hispanica sp. nov. by the conical shape of its actines. C. conifera , C. helveola and C. hondurensis sp. nov. have conical actines similar to those of C. sinusarabica . However, C. conifera has blunt tips, while C. sinusarabica has strong, sharp tips. C. helveola and C. hondurensis can be distinguished from C. sinusarabica by the size of the tricatines, which are shorter and thinner in the latter.
