A review of the brachylepadomorph cirripede genus Pycnolepas, including the first record of an Early Cretaceous species from the Russian Far East * Author Jagt, John W. M. Author Zonova, Tatiana D.

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.
