Gymnocyst encircling entire autozooid, generally narrow throughout but may be a little broader proximally or proximolaterally. Cryptocyst and opesia encircled by a continuous raised granular rim (CrL 365–656 (500); CrW 299–361 (299)]; cryptocystal shelf moderately broad, gently sloping towards opesia, attenuating in width towards orificial area, evenly granular except for a smooth band bordering opesia. Opesia more or less narrowly elongate-oval, generally broader proximally, proximal margin evenly rounded or obliquely so [OpL 231–500 (353)]. Articulated pericryptocystal spines

No avicularia. Ooecium hyperstomial, smooth-surfaced, about as wide as long or wider; tilting reveals a narrowly transverse or compressed subarcuate ectooecial excavation facing proximad, not seen in frontal view [OoL 176–221 (208); OoW 211–223 (213)]. Ooecial kenozooid wholly concealed by ooecium. Interzooidal kenozooids generally well developed, infilling spaces between disjunct autozooids, each with a sloping gymnocyst surrounding a small central opesial foramen surrounded by a concentric area of granular cryptocyst; similar kenozooids form within some autozooidal cystids by regenerative budding, superficially appearing as opesial closure plates. Position of frontally damaged ancestrula indicated only by a thin lateral wall.
