Actinostoloidea CARLGREN 1932

Description

SUPERFAMILY ACTINOSTOLOIDEA CARLGREN, 1932

Diagnosis (after Gusmão et al. (2019) with additions in italics). Enthemonae usually with basilar muscles, mesogleal marginal sphincter and no acontia or acontioids; rarely lacking basilar muscles and marginal sphincter muscle. Aboral end mostly flat and adherent; sometimes with physa. Column usually smooth; rarely with cuticle and rows of tubercles. Mesenteries usually not differentiated into macro- and microcnemes; rarely differentiated into macro- and microcnemes. Mesenteries of same pair often unequally developed. Retractors usually diffuse weak or strong, sometimes circumscribed. Cnidom: gracile spirocysts, basitrichs, holotrichs, b -mastigophores and p-mastigophores A.

Included families: Actinostolidae, Exocoelactinidae, Halcampoididae and Halcampulactidae.

Remarks: We modified the diagnosis of the superfamily Actinostoloidea to reflect the characters observed in the new species (Chitinactis marmara; e.g. rows of tubercles formed by thickenings of mesoglea and strong cuticle on column). In addition, we modified the superfamilial diagnosis to reflect recent changes in the higher level classification of Actiniaria (i.e. Rodríguez et al., 2014) and the nematocyst terminology used in this study (see: Gusmão et al., 2018). These modifications have been made in all other diagnoses included in this study.
