Stenomacrus celer (Holmgren, 1858)

Stenomacrus spp. are generally smaller species with the lower edge of the clypeus truncate or subtruncate and without a closed areolet. The prepectal carina is present, just like the lower tooth of the mandible, which is located on the inner edge of the mandible ( TOWNES, 1971).

Stenomacrus celer is a small species ( 2.5 mm) with a ‘knife-like’ compressed metasoma, without any long hairs. Its postannellus measures more than three times its width ( AUBERT, 1981). First report for the Netherlands; unreported in Belgium.
