Abstract
Additional specimens of Collinsius simplex Karasawa, 1993, a species first described from the Kishima Formation (Lower Oligocene, uppermost part of calcareous nannofossil zone CP16a), are recorded from the Upper Eocene– Lower Oligocene (CP15b– CP16a) Funazu Formation (Iojima Group) and the Lower Oligocene (CP16b) Itanoura Formation (Nishisonogi Group) in Kyushu, south- west Japan. This material extends the stratigraphical range of Collinsius simplex further back into the Late Eocene. In addition, a new species of ghost shrimp, Vecticallichirus kawanoi sp. nov., is described from the middle part of the Funazu Formation (Upper Eocene). This has a blade with ap- proximately 10 serration- like spines on the lower margin of the merus, a long carpus with an unarmed margin and a molar- like triangular tooth proximally on the occlusal margin near the base of fixed finger. It appears closest to V. batei (Woodward 1869), but differs in that the carpus has an unarmed lower margin; the same holds true for the fixed finger.
