Monomorium subopacum (Fr. Smith) ^HNS

Similar in general form as M. pharaonis ^HNS and the body is without erect hairs; clypeus without the medial notch as in M. salomonis ^HNS. Originally described from the Azores, M. subopacum ^HNS has been recorded from Antigua in the Lesser Antilles (Kempf, 1972).
