Rissoa sculptilis Rissoa

sculptilis, Rissoa [Alvania sculptilis (Monterosato, 1877)] (Figures 16C, D)

1877a: 35, pl. III, fig. 6 [(XV: 305, 322, fig. 6]—available name

Type material. MCZR –M–22162 —3 sh “ Rissoa sculptilis n. sp? Alger (Joly)”.

Type locality. Described from coasts of Algeria.

Remarks. Recorded by MolluscaBase (2018) as Alvania sculptilis (Monterosato, 1877). Villari & Scuderi (2017) commented on potential relationships with Alvania sororcula Granata-Grillo, 1877 without reaching a conclusion.

scurra, Apicularia [Rissoa scurra (Monterosato, 1917)]

1917: 12, pl. I, figs 27, 28 [(LXVII: 1286, 1305, pl. I, figs 27, 28]—available name

Type material. Not found in MCZR.

KBIN –D – Lectotype (ex Monterosato) designated and figured by Verduin (1985: 120), from “ Puntebianche ”. Type locality. Puntebianche (Croatia). Described also from Tripoli (Libya).

Remarks. Recorded by MolluscaBase (2018) as Rissoa scurra (Monterosato, 1917).

simplicula, Cingula [Crisilla simplicula (Monterosato, 1890 nomen dubium] (Figures 16H, I)

1890a: 147 [XXXVIIIa: 901]—available name

Type material. Not found in MCZR.

Other material. MCZR –M–30018 —2 sh “Cingula simplicula Monts. Pal !! Conch. Prof. Pal. p. 8”

Type locality. Described from Palermo (Sicily).

Remarks. The two shells in the collection do not match the description (the figured shell is a juvenile of the Rissoa lia –complex), raising misplacing as very likely. In the original description, Monterosato compared it to the group of Rissoa aemula (a nomen nudum that, according to material in the collection, was based on Crisilla gagliniae (Amati, 1985) [new combination]). We therefore ascribe Cingula simplicula to the genus Crisilla [new combination] (as defined in Bouchet & Warén, 1993), but keep the species as a nomen dubium, pending the finding of actual types (not recorded by MolluscaBase, 2018).

† spinosa, Alcidia [Alvania spinosa (Monterosato, 1890)] (Figures 16J, K)

1890a: 147 [XXXVIIIa: 901]—available name

Type material. MCZR –M–30019 —3 sh “ R. angulata Seg. ms. foss. di Milazzo”// 2 sh “ Alcidia spinosa Seg. Palermo 1886 ” Label on the bottom: “ Alcidia spinosa Monts. ms. = angulata (non Eichw) Seguenza Palermo. 1886” Type locality. Described from Milazzo † and Palermo (Sicily).

Remarks. Name proposed to replace “ R[issoa]. angulata Seguenza ms.” (nomen nudum in Seguenza 1874: 4) non Eichwald, 1830, included in the new section Alcidia. Recorded by MolluscaBase (2018) as Alvania spinosa (Monterosato, 1890).
