Protobombus sp. indet.

MATERIAL: One specimen. Non­type. Female, Nr. 1962.I.262 ( BSPG): labeled ‘‘Bay­ er. St. Slg. Paläont. Hist. Geol. ( BSP), Nr. 1962.I.262, Apidae, Honigbiene, Unteroligozän , Ostpreussen’’ // ‘‘ Protobombus sp. indet., det. M. S. Engel, 1999’’.

COMMENTS: This specimen is in exceedingly poor shape. The bee is almost completely pyritized. The general habitus, presence of a corbicula, and quadrangular metabasitarsus suggests a species of Protobombus . The identity of this specimen will probably never be known with any reasonable degree of certainty.
