Pycnolepas fimbriata (Withers, 1912)

Original description. Withers (1912: 506, pl. 23, fig. 1a, b, as Brachylepas (?) fimbriatus) [see also Withers 1928: 91, pl. 12, figs 9–12].

Type. Holotype is a carina in the M. Remeš Collection (Olomouc), an ‘electrotype’ of which is NHM I.15818.

Locality and stratigraphy. Stramberg (= Štramberk), Moravia (Czech Republic); Red Limestone, Tithonian (141–135 Ma).

Remarks. The single carina known of P. fimbriata is semicylindrical, strongly convex transversely, noncarinate and comparatively small (length c. 13 mm), with a near-straight basal margin; ornament consists of regularly spaced, prominent, transverse and rounded longitudinal ridges. Two other capitular valves have been referred to this species, albeit with a query. One is a fragmentary tergum (Withers, 1928: pl. 12, fig. 11; Red Limestone, Nesselsdorf = Koprivnice), with a straight apicobasal ridge; the other a fragmentary?rostrum (Withers, 1928: pl. 12, fig. 12). In the absence of other valves, assignment to Pycnolepas must remain tentative; Withers (1928: 93) noted a general resemblance to the carina of P. rigida .

Occurrence. Known only from the Red Limestone (Tithonian) of Štramberk and Koprivnice, Moravia (Czech Republic); no subsequent records.
