commutata, Scalaria [Gyroscala commutata (Monterosato, 1877)] taxon inquirendum (Figures 10K, L)
1877d: 420 [XIII: 356]—available name
Type material. MCZR–M–23554— 2 sh “ S. commutata, Monts Ann. Museo Civ. Genova 1876 —77 p. 14 = S. pseudoscalaris, auct. (non Brocc.) Palermo e Catania!”
MCZR –M–23529 —10 sh “ Sc. commutata albida Alger coll (Joly)”
MCZR –M–23556 —7 sh “ Sc. commutata var. albina. M. Oran (Alg)”
Type locality. Civitavecchia (Italy) and Mediterranean.
Remarks. Name proposed to distinguish Scalaria pseudoscalaris Brocchi, 1814 sensu Auctores, considered as a distinct species by Monterosato based on the lack of spines at the axials. The alleged synonymy with Scalaria lamellosa Lamarck, 1814 (from Western Atlantic) was initially considered as possible by Monterosato’s (1877d: 420) but subsequently (Monterosato, 1878c: 26) rejected. Some Authors have considered the introduction by Monterosato as a replacement name for Scalaria lamellosa Lamarck, 1822 [not Turbo lamellosum Brocchi, 1814 — now Cirsostrema lamellosum (Brocchi, 1814)]. Landau et al. (2006: 18) debated the issue of the name to use for the species, deciding for Epitonium commutatum (Monterosato) [now Gyroscala commutata]. Considering other cases of species from the two sides of the Atlantic almost indistinguishable morphologically (see e.g. Bulla striata Bruguière, 1792 v. B. occidentalis A. Adams, 1850: Malaquias & Reid, 2008) we take a conservative position in regarding the introduction by Monterosato (1877d: 420) as a new species. In case the two entities (Eastern v. Western Atlantic) are considered as conspecific, then the name for both should be Gyroscala commutata (Monterosato, 1877); in case they are proved (for instance by genetics) as distinct, then G. commutata should be restricted to the Eastern Atlantic species. Recorded by MolluscaBase (2018) as a synonym of Gyroscala lamellosa (Lamarck, 1822), we suggest reverting to Gyroscala commutata (Monterosato, 1877) as taxon inquirendum [new status].
