Euspira intricata Philine

intricata, Philine [Philine intricata Monterosato, 1884] (Figures 29C, D)

1875b: 47 [XIII: 273]—nomen nudum

1878c: 111 [XIX: 425]—nomen nudum

1878b: 319 [XXI: 459]—nomen nudum

1884h: 147 [XXXI: 803]—available name

Type material. MCZR–M–16301 —28 sh + frg “ Philine intricata, Monts. Palermo!”.

Type locality. Described from Palermo, Trapani and Messina (Sicily), Algiers (Algeria).

Remarks. Giannuzzi– Savelli & Piani (1990: 173) overlooked the valid introduction of the name in Monterosato (1884h), by means of a description. The material of P. intricata in the Monterosato collection was examined by Gaglini (1991: 12; 20, unnumbered figs). The species was also treated by van der Linden (1994), Oliverio & Tringali (2001: 135; 124, figs 8a–c; 134, figs 59–60), and Tringali (2001: 216–217, figs 33, 41; 218, figs 48, 49a– b). Its shell is characterised among the Eastern Atlantic–Mediterranean philinds by the strong columellar fold. A strong fold is also displayed by Philine angulata Jeffreys, 1867, the latter being otherwise readily distinct by its general shape. Tringali (2001: 216, fig. 41) found a gizzard plate in a partially preserved specimen. Recorded by MolluscaBase (2018) as Philine intricata Monterosato, 1884.

monterosati, Philine [Philine monterosati Monterosato, 1874 ex Jeffreys ms.] (Figures 30A, B)

1874a: 281 [X: 207]—available name

Type material. MCZR –M–16303 —4 sh mostly damaged + several frg “ Philine monterosati Jeffr. Palermo !!” // 1 sh “ monterosati Pal. !!”. Label on the bottom: “ Philine monterosati Jeffr. ms. 90–210!!” and a note on the cork cap “P. 1874”.

Type locality. Described from San Vito lo Capo and Palermo (Sicily).

Remarks. The species was discussed by Bouchet (1975: 356–358, figs 19A–D, pl. 4 fig. j) and by Oliverio & Tringali (2001: 137–138; 124, figs 5a–d; 136, figs 65a–f, 66, 67, 69, 70, 71a–d; 138, figs 72a–j), who provided data and a rich iconography. The latter work examined and discussed the whole P. monterosati material stored in the collection, documenting the type material. We refer to it for more details. Recorded by MolluscaBase (2018) as Philine monterosati Monterosato, 1874.

striatula, Philine [Philine striatula Monterosato, 1874 ex Jeffreys ms.] (Figures 31A, B)

1872b: 55 [VI: 137]—nomen nudum

1874a: 281 [X: 207]—available name

Type material. MCZR –M–16322 —12 sh + frg “P” marked on the cork cap standing for “Palermo”// 2 sh “San Vito”. Two labels on the box bottom: “ Philine incerta n. sp. Inedita Palermo 30 m anche d'Algier 40 m Joly” and “ Philine striatula, Jeffr. Palermo e S. Vito!”;

Type locality. Described from San Vito lo Capo (Sicily).

Remarks. Philine striatula is a peculiar species among the norheastern Atlantic and Mediterranean Philinidae s.l., with its slender shape, prominent protoconch, and numerous, fine chain–like rows of minute dots. The general shape varies with growth, as is observed also in other philinids—e.g. Philine catena (Montagu, 1803), Philine intricata Monterosato, 1884, Philine iris Tringali, 2001 —larger shells (presumably older) becoming stouter and wider at the base. The type material (revised and figured by Oliverio & Tringali, 2001: 138–139; 124, figs 7a–c; 140, figs 73a–c, 75a–b) is emblematic of this growth–related morphological variation. Malaquias et al. (2016) studied the anatomy of Philine striatula on West African material (wrongly identified as “ Philine intricata Monterosato, 1884 ”). Crocetta & Tringali (2017) discussed in further detail the species identity and its synonymy. Recorded by MolluscaBase (2018) as Philine striatula Monterosato, 1874.
