Diagnosis
Actinostolidae with broad base. Column smooth, variable in thickness, margin tentaculate. Sphincter mesogloeal strong so that the upper part of the body can cover the tentacles. Tentacles short, conical, fairly numerous without mesogloeal thickenings on their outer sides, with large microbasic b-mastigophores in their distal parts. Longitudinal muscles of tentacles mesogloeal to ecto-mesogloeal, radial muscles of oral disc mesogloeal. 2 well developed siphonoglyphs. Tentacles and pairs of mesenteries frequently arranged 16 (6+10), 16, 32; 16-18 pairs perfect. Perfect mesenteries generally sterile but when the perfect pairs are more than 16 the exceeding pairs are often fertile, at least the stronger imperfect mesenteries fertile. Considerably more mesenteries at the base than at the margin. In the youngest cycles the mesenteries of one and the same pair are unequally developed in such a way that the partner furthest away from the adjacent mesenterial pair of the next oldest cycle is the larger (as in Actinostola). Retractors diffuse, well developed, parietobasilar and basilar muscles strong. Cnidom: spirocysts, basitrichs, microbasic b- and p-mastigophores.
