, hence small and spot-like [ZL 274–418 (344); ZW 210–322 (263)]. Gymnocyst quite well developed, continuous around zooid. Cryptocyst and opesia surrounded by a distinct raised rim [CrL 190–203 (198); CrW 152–173 (163)], the cryptocystal shelf fairly extensive, sloping toward opesia, attenuating laterally as far as orificial area. Opesia longer than wide, constricted in middle, imparting a broad dumbbell shape [OpL 83–95 (90)]; distal margin evenly rounded, proximal margin somewhat straighter, sometimes obliquely so. Oral and pericryptocystal spine bases present, up to 10 visible, 11 likely in life; no accessory gymnocystal spine bases on best-preserved zooids. Avicularia interzooidal, more than half autozooid length, cystid with extensive gymnocyst, rostrum elongate, narrow, acute, apparently no pivot bar, opesial foramen wider than rostral palate [AvL 193–263 (236); AvW 188–267 (230)]. Ooecium hyperstomial, smooth with median suture line [OoL 114–152 (140); OoW 135–183 (158)]; ooecial kenozooid visible distally, with circular area indicating presence of foramen and cryptocyst in life. Ancestrula small, circular, with periopesial/pericryptocystal spines [AnL 153; AnW 145].

colony is unusually small, being less than half the size of daughter zooids (unless there is a proximal portion missing). There is a hint of periopesial spine bases so it could have been tatiform in life; alternatively, there may have been a cryptocyst, which is likely. Daughter zooids have occluded opesiae, indicating the presence of kenozooidal regeneration within the cystids, but recrystallisation precludes certainty.
