Hincksina longispinosa Harmelin & d’Hondt, 1992 View in CoL
( Fig. 6 View FIGURE 6 )
Hincksina longispinosa Harmelin & d’Hondt, 1992a: 32 View in CoL , pl. I, fig. d–f.
Material examined. MNCN 25.03/4290; MNCN 25.03/4291: BV12, 112– 120 m; coll. UMA; five and two living fragments, respectively; all specimens encrusting shell fragments.
Description. Colonies encrusting, unilaminar ( Fig. 6A, B View FIGURE 6 ). Zooids hexagonal, longer than wide [L 430–495– 571 (N 14, SD 37), W 265–309–340 μm (N 17, SD 31)] ( Fig. 6B View FIGURE 6 ). Gymnocyst reduced, bearing thin, delicate spines numbering four on the oral region, directed frontally, and 10–12 encircling and overarching the opesia ( Fig. 6A View FIGURE 6 ); cryptocyst negligible. Avicularia interzooidal, longer than wide [L 96–108–124 μm (N 7, SD 15)], placed on a developed cystid and directed longitudinally but usually transversely when associated with an ovicell ( Fig. 6B, C View FIGURE 6 ); mandible semi-circular, hinged on a small pair of denticles ( Fig. 6C, D View FIGURE 6 ). Ovicell large [L 93–200–223 (N 9, SD 17), W 207–235–254 μm (N9, SD 18)], immersed in the avicularium cystid ( Fig. 6C, D View FIGURE 6 ).
Remarks. Hincksina longispinosa was described and uniquely recorded from the Gulf of Cadiz in two different depth zones, 137–150 m and 460–524 m ( Harmelin & d’Hondt 1992a). This record expands its geographic distribution to the Alboran Sea at slightly shallower depths (112–120 m). In comparison with the Gulf of Cadiz, the material collected on the Alboran platform has shorter avicularia (L 96–124 vs 141–148 µm).
