? Scrupocellaria reptans (Linnaeus) : Zabala i Limosin 1986: 321, fig. 90. [Mediterranean]

Scrupocellaria ellisi Vieira & Spencer Jones, 2012: 34 , fig. 4, 18–23, 25, 27 (cum syn.).

Diagnosis. Chitinous joints passing across gymnocyst in outer zooids at bifurcation (zooids C and D); 1 long distal spine, 3 outer spines and 1–2 inner spines; axial zooid with 5 distal spines; scutum more branched than in C. reptans , occupying almost entire opesial area, flattened, branched 2–3 times, with 8–13 stout projections at distal tips; scutum angled at 115–155°, with first branches about 0.046 –0.060 mm wide, secondary branches about 0.035 –0.045 mm; small distolateral avicularum sometimes present, obscured by outer oral spine; rhizoids smooth; ooecium with 12–18 small rounded pseudopores.

Remarks. Cradoscrupocellaria ellisi was previously misidentified as Scrupocellaria reptans , but Vieira and Spencer Jones (2012) distinguished C. ellisi by the presence of smooth rhizoids, stouter scuta and the size of oecial pseudopores, smaller in C. ellisi than in C. reptans .

The misidentifications of specimens assigned to C. macrorhyncha ( Gautier, 1962) and C. reptans suggest that Gautier’s species has never been redescribed or figured since its original description (see Zabala & Maluquer 1988). In the present paper we redescribe Gautier’s specimens to distinguish it from C. ellisi and C. reptans . Cradoscrupocellaria macrorhyncha is distinguished by the shape of frontal avicularia and the number of distal spines (see below). The specimens from the Mediterranean reported as Scrupocellaria reptans by Zabala i Limosin (1986), may belong to C. ellisi .

Distribution. Widespread in Northeast Atlantic to the North Sea; Adriatic; western Mediterranean?; Tasmania.
