Totton, 1954

Very characteristically shaped, elongate nectophores with large triangular thrust block and axial wings virtually absent. Apico-lateral ridges each divide above the ostium. Highly oblique vertical lateral ridges join infra-laterals close to the ostium. Long, narrow nectosac with straight radial canals. Bract broad and rounded with many patches of cells on its dorsal surface.
Totton (1965) included this genus in the family Pyrostephidae. Although there are some similarities with the single species in that family, for the present we follow Stepanjants (1967) and include the genus in the family Agalmatidae. Nevertheless, it is certain that its status will need further review. Margulis (1982) described a new species Mica micula that appears to be the post-larval stage of a physonect siphonophore and, from the shape of the nectophores, it is suggested that the species to which it belongs is Bargmannia elongata.
