Laeviranina hollandica, a new Late Oligocene(?) raninid (Crustacea, ) from The Netherlands.

JOE S. H. COLLINS, RENÉ H. B. FRAAYE, JOHN W. M. JAGT & PAUL H. M. VAN KNIPPENBERG

Abstract: A new species of raninid crab, Laeviranina hollandica, is described from Winterswijk-Miste (province of Gelderland, The Netherlands). Having been collected from a remanié fauna yielding a number of typically Late Oligocene (Chattian) molluscs, at the base of the Aalten Member (Breda Formation, Early , Hemmoorian/Oxlundian), its age is, most probably, Late Oligocene. The new species may thus represent the youngest known member of the genus, hitherto restricted to the .

Van den Bosch et al. (1975: 22) remarked that, 'At some Dutch occurrences recorded in the literature (Holthuis, distance from the base a horizon of phosphorite concretions 1949; Collins & Fraaye, 1991). The decapod containing glauconite has locally been found in situ (not fauna from the reworked phosphorite concretions at the reworked). Elsewhere, however, similar concretions, base of the Miste Bed has not yet been studied in detail, and presumably from the same horizon, are found as reworked the present record of a raninid crab is the first from these components at the base of the member, so far only at places concretions. where the Hiatella arctica Acme Zone is missing.
