( Fig. 12 )

Lepralia complanata Norman, 1864: 85 , pl. 10, fig. 4.

Watersipora complanata: Zabala 1986: 395 , fig. 128; Hayward & Ryland 1999: 192, figs 74b, 75; Reverter-Gil & Fernández- Pulpeiro 2001: 122; De Blauwe 2009: 372, figs 397, 398; Reverter-Gil et al. 2014: 26.

Terwasipora complanata: Reverter-Gil & Souto 2019: 2743 , figs 5, 6, 8.

Material examined. MNCN 25.03/4282 : BV12, 112– 120 m; UMA coll.; one dead fragment on shell; MNCN 25.03/4283 : BV12, 112– 120 m; UMA coll.; four living fragments on shell and three loose dead fragments.

Remarks. Several specimens from the Mediterranean Sea assigned to T. complanata were reviewed by Reverter- Gil & Souto (2019), who maintained as valid the records of this species from Catalonia and the Strait of Gibraltar ( Zabala 1986; López de la Cuadra & García-Gómez 1988; López de la Cuadra 1991; see Reverter-Gil & Souto 2019 for comments about its geographic distribution).

The Alboran colonies have slightly smaller zooids (L 600–800 μm x W 350–600 μm) but within the range reported by Reverter-Gil & Souto (2019).
