Cradoscrupocellaria serrata ( Waters, 1909) n. comb.

Scrupocellaria serrata Waters, 1909: 133 , pl. 10, figs 11–14. [Red Sea]

Remarks. This species is characterized by zooids with 1 inner and 2 outer distal spines, spine-like, sometimes branched scuta, no basal vibracula, serrated rhizoids, and neither frontal nor lateral avicularia, except in ovicelled zooids where distolateral avicularia with large bi- or trifurcated rostra are present.

Cradoscrupocellaria serrata is distinguished by the absence of lateral avicularia in non-ovicelled zooids, in having ovicelled zooids with large bi- to trifurcated avicularia, and no basal vibracula. The shape of the large lateral avicularia has been described in four Scrupocellaria species : Scrupocellaria obtecta Haswell, 1880 (see MacGillivray 1886, pl. 126, fig. 5), Scrupocellaria talonis Osburn, 1950 (see Osburn 1950, pl. 17, fig. 3), Scrupocellaria unguiculata Osburn, 1950 (see Osburn 1950, pl. 17, figs 1–2) and Scrupocellaria varians ( Hincks, 1882) (see Hincks 1882, pl. 19, fig. 1a–b). Both S. obtecta and S. unguiculata are distinguished from the present species by their rounded scuta. Scrupocellaria talonis specimens are distinguished by their smooth rhizoids, zooids with dimorphic lateral avicularia, the usual presence of 1 inner and 1 outer orificial spines (sometimes these spines are absent) and the inner edge of the opesia has a rare, vestigial spine-like scutum; no ovicells were found in the specimens described by Osburn (1950). The scutum and gigantic lateral avicularia of S. varians resemble those described for C. serrata , but S. varians is distinguished by its small lateral avicularia, basal vibracula and ovicells with a single pore in the ectooecium.
