Masuko leg., 19/ix/1982 ]; Ishikawa: Kanazawa: Kakuma, 1 worker [S. Iwanishi leg., 23/ix/2007 ]. Remarks. The worker and queen of B. caliginosa is easily distinguished from those of B. cryptica by: (1) anteromedian portion of clypeus lacking a pair of extremely long and flexible setae; (2) frontal carinae inconspicuous, extending by no more than the length of frontal lobe; (3) posterolateral part of propodeum feebly produced posteriad. Furthermore, the worker of B. caliginosa is distinguished from that of B. cryptica by the 9th and 10th antennal segments each (a little) shorter than long.
