Pycnolepas paronai ( De Alessandri, 1895)

Original description. De Alessandri (1895: 266, pl. 3, fig. 8a–f, as Pollicipes paronai ).

Type. Lectotype, designated by Withers (1914:185), is an unregistered scutum, illustrated by De Alessandri (1895: pl. 3, fig. 8a, b), contained in the Luigi Di Rovasenda Collection (now at the Museo Regionale di Scienze Naturali, Torino).

Locality and stratigraphy. Chieri, southeast of Torino, northern Italy; lower Miocene (Aquitanian, c. 23–22 Ma)

Remarks. All valves of P. paronai have numerous, close-set transverse and longitudinal ridges; carina narrowly semiconical; scutum with apical part attenuated, much incurved, and longitudinal ridges fine, wavy and radiating from apicobasal ridge; inner occludent edge very wide, extending more than halfway across valve; tergum with apicobasal ridge straight; inner occludent and tergal edges widely raised. Upper latus and imbricating plates unknown.

Occurrence. Withers (1953) recorded material from the lower and middle Miocene (in his terminology: Aquitanian and Helvetian, respectively) of the environs of Torino (Chieri, Baldisero and Sciolze [St. Antonio], northern Italy), which would now be equivalent to the lower Miocene (Aquitanian and Burdigalian; see Kroh, 2005: table 1).

Occurrence. Known only from the type locality; no subsequent records.
