I have been unable to obtain an authentic specimen of the type species, but judging from the published descriptions, its affinities are with the forms included in the family Amplexopobid^. Most of the forms described under the name Diplotrypa are not congeneric with the type species. Family Calloporidae, Ulrich, emend. The forms included in this family are usually ramose, cells tubular, cylindrical, tabulate; mesopores more or less abundant, closely tabulate; interapertural space with pits (mesopore aper- tures)..
