Paraedwardsia Carlgren  in Nordgaard, 1905

Edwardsiidae  with body divisible into scapus and capitulum; no physa, or only weakly developed one. Scapus lacks nemathybomes but has periderm and scattered tenaculi to which grains of sand adhere. Epidermis of scapus with abundant nematocysts that sometimes form groups; nematocysts of scapus and scapulus of about equal size. At least eight microcnemes. Tentacles typically 16 or more in adults, arranged octamerously or hexamerously, inner ones longer than outer ones. Retractor muscles relatively large, well­developed, reniform; parietal muscles distinct, symmetrical. Cnidom: spirocysts, basitrichs, microbasic p ­mastigophores. (Modified from Carlgren, 1949 to eliminate redundancies with familial diagnosis.)

Type species. Paraedwardsia arenaria Carlgren  in Nordgaard, 1905 by subsequent designation ( Carlgren 1921, Fautin et al. 2007).
