Diagnosis. Metaventrite with a pair of setiferous patches between metacoxae; abdominal tergites in male lacking setiferous patches, excavation on tergite VI occasionally present; tergites V–VI sparsely covered with sensory setae.

Remarks. The species of this group may be recognized by their setiferous patches between the metacoxae, the abdominal segments lacking an excavation or setiferous patch (except for B. similis and B. shiranui ), and the presence of sensory setae on tergites V–VI.

The group contains seven species previously placed in the subgenus Scaioscenellus , six are restricted to Japan, and one is recorded from the Korean Peninsula southward to Taiwan.
