Pycnolepas orientalis Kolosváry, 1966 (nomen dubium)

Original description. Kolosváry (1966: 130, text-fig. 2).

Type. Not indicated; current whereabouts of material unknown.

Locality and stratigraphy. Kuznataj (= River Kuzna-chaj, Azerbaijan); Upper Cretaceous (exact level not specified).

Remarks. The type lot (collected 1958; leg. V.G. Nikitin) of this form consists of isolated capitular valves; Kolosváry referred to these as scutum, carina, carinolaterale, tergum, rostrum and supralaterale. As noted by Collins (1980: 21), the ‘scutum’ in Kolosváry’s fig. 2a clearly is a tergum, while the ‘tergum’ of his fig. 2d is a scutum; that this was intentional can be seen from the description and reconstruction of the capitulum ( Kolosváry, 1966: fig. 7). Kolosváry failed to explain why this form should have had three pairs of lateral valves, while the genus Pycnolepas has a single pair (see Withers, 1914, 1935). Alekseev (1979: 17) clarified the provenance of the material by noting that (translated), ‘In the same year, G. Koloshvary ( Kolosvary, 1966) based on material from Caucasus, received from O.S. Vialov, briefly described the new species Pycnolepas orientalis ( Azerbaijan, River Kuzna-chaj, Upper Cretaceous) and the new subspecies Zeugmatolepas mockleri armenicus ( Armenia, Maastrichtian), without pictures giving only schematic drawings’. We consider it best to treat P. orientalis as a nomen dubium until the types are traced, or new material is collected, so as to allow a proper interpretation of this form.

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