2016 Oncopareia klintebjergensis Jakobsen and Collins ; Feldmann et al., p. 23, fig. 20.3c-d

Material examined. Holotype MGUH 14437

(incomplete cephalothorax), paratype MGUH

14438 (right cheliped fingers).

Diagnosis. Oncopareia with long, almost straight orbital margin; cervical and combined branchialpostcervical grooves concave-forward and with two spines behind orbit.

Remarks. Oncopareia klintebjergensis is based on the anterior portion of a single cephalothorax and part of its associated right cheliped ( Jakobsen and Collins, 1979). The species differs from O. bredai in several aspects, including the longer, shallower orbits, the more ventral position of prominence “ω” on the carapace, and in the claw denticles which are angled distally.

Range and occurrence. Paleocene Lellinge Greensand Limestone of Klintebjerg, eastern Sjaelland, Denmark.
