Appolloni, Massimo, Smriglio, Carlo, Amati, Bruno, Lugliè, Lorenzo, Nofroni, Italo, Tringali, Lionello P., Mariottini, Paolo & Oliverio, Marco, 2018, Catalogue of the primary types of marine molluscan taxa described by Tommaso Allery Di Maria, Marquis of Monterosato, deposited in the Museo Civico di Zoologia, Roma, Zootaxa 4477 (1), pp. 1-138 : 74

effusa , Coleophysis [ Retusa truncatula (Bruguière, 1792) ] ( Figures 32A, B )

1890c: 188 [XXXVIII c: 922]—available name

Type material. MCZR–M–16030 —4 sh “n.sp. Palermo 1886”

Type locality. Described from Palermo (Sicily), and Villefranche-sur-Mer ( France).

Remarks. The recognition of the type material was discussed by Oliverio & Tringali (2001: 131; 124, fig. 9, 128, figs 31–32, 132, fig. 52). This species needs to be revised in the framework of a complete revision of the Retusa truncatula (Bruguière, 1792) complex. Recorded by MolluscaBase (2018) as a synonym of Retusa truncatula (Bruguière, 1792) .

minutissimus, Utriculus [ Retusa minutissima (Monterosato, 1878 ex H. Martin ms.)] ( Figures 32C–E )

Type locality. Described from Golfe de Fos ( France) , Vado and Livorno (Italy), Algiers ( Algeria) .

Remarks. Type and non– type material in the Monterosato collection was commented by Oliverio & Tringali (2001: 131, 133–135, 124, figs 2a–b; 128, fig. 38a–b; 130, figs 41–42), who also discussed its identity, the distinction from the similar Retusa obtusa (Montagu, 1803) , and documented shell variation and gizzard plates morphology, concluding on its actual belonging to the genus Retusa T. Brown, 1827 . Recorded by MolluscaBase (2018) as Retusa minutissima (Monterosato, 1878) .
