Scrapter ruficornis subgroup

In this subgroup both sexes have a brownish pronotal lobe and metasomal integument. Males: S7 with apicolateral hairs and/or disc of T2–T3 sparsely punctate; the fine and dense punctation at the base of T2 covers at most about a quarter of the tergal length. Females: mesosoma often partly orange and propodeum mostly areolate. This subgroup comprises three species ( Table 1 ).
