Family Heteralepadidae Nilsson-Cantell, 1921

Thick walled, globular capitulum supported by stout peduncle infrequently several times its length; both may be relatively smooth, wrinkled or bumpy; capitulum may support several protrusions or a crest along carinal margin; aperture may be low, inconspicuous, with smooth or sometime protuberant margins that are rarely flaring; cirri generally ctenopod or acanthopod, rarely lasiopod, second generally found in symbionts of large invertebrates rather than free-living forms. Family presently consisting of two genera, Heteralepas Pilsbry, 1907 and Paralepas Pilsbry, 1907 .

Remarks. When Pilsbry (1907) revised Alepas , he extracted two distinct but related taxa from it, the new genera Heteralepas and Paralepas . He placed them in the family Lepadidae , where they remained until 1921. Nilsson-Cantell (1921) noted that these two genera, in addition to lacking calcareous plates, differed from the remaining Lepadidae in the nature of their trophi and cirri and, therefore, proposed a new family for them, the Heteralepadidae .
