Halopteris tenella (Verrill, 1874)

Synonyms in the area: Halopteris constricta —Migotto 1996 [part]; Oliveira 2003; Oliveira et al. 2006 [polyp]; Schizotricha tenella —Calder & Maÿal 1998 [polyp].

Remarks: Galea (2013 p. 34) remarked that some materials listed herein, like that by Migotto (1996, in part, see below), “may belong” to Halopteris tenella (Verrill, 1874) . Close comparisons of both materials, including molecular analysis, are necessary to resolve this doubt.
