　 房総半島から小笠原諸島，貝類の殻，石灰藻類，フジツボ類に穿孔（Sato-Okoshi 1999）．
　 模式産地はマデイラ（Blake 1996）．

　 Dipolydora Verrill 1879 emend Blake 1996 は日本周辺海域から10種を超える報告があるが （Okuda 1937, Imajima Hartman 1964, Radashevsky 1993, Blake 1996, Sato-Okoshi 1999, Sato-Okoshi 2000, etc.）， アセス関連データでは Polydora sp./spp. に混同されたものが少なくないものと想像される．
　 腹足枝鉤状被嚢剛毛の形態と第1背足枝剛毛の有無で両属の識別ができる（Blake 1996）．
