Material examined. Holotype: USNM 376607, ‘ Trematooecia turrita’, J.E. Winston det., 1984, Carrie Bow Cay, Belize.
Diagnosis. Encrusting Cigclisula with zooids limited by distinct wavy grooves; 2 or more frontal avicularia per zooid; ooecium immersed, ectooecium with longitudinal band of 3–9 irregular large (0.020 –0.056 mm diameter) pseudopores.
Etymology. Named after Judith Ellen Winston, for her contribution to bryozoology.
Description. Colony encrusting, uni- to multilaminar forming small mounds. Zooids irregularly polygonal, as long as wide, limited by distinct wavy grooves. Frontal shield thickly calcified, irregularly punctured by 23–46 pores. Primary orifice large relative to frontal shield, centered, oval, longer than wide, sunken, with arcuate anter and slightly narrower concave poster, separated by 2 down-curved condyles. Secondary orifice frequently surrounded by 4–5 (usually 4) long solid tubercles. Suboral avicularium absent. Frontal avicularia small, elliptical, usually 2–3 per zooid, on frontal shield between tubercles near orifice; serrated distal rostral margins. Interzooidal avicularia smaller than zooids, short, rostrum spatulate, wider than long, proximal edge rounded and distal edge concave; calcified palate occupying less than half rostral length, with rounded foramen. Ooecium fully immersed; ectooecium with longitudinal band of about 3–9 irregular large (0.020 –0.056 mm diameter) pseudopores.
Remarks. Although identified as Trematooecia turrita (Winston 1984; Winston & Wollacott 2009), the morphology of the ooecium is strikingly different between C. turrita and C. winstonae n. sp. Whereas C. turrita has a prominent ovicell and ectooecium with a longitudinal band of 25–38 pseudopores, C. winstonae n. sp. has an immersed ovicell and ectooecium with a longitudinal band of 3–9 large pseudopores. The species also differ in the shape of the interzooidal avicularia—linguiform in C. turrita, spatulate in C. winstonae n. sp.
Cigclisula winstonae n. sp. and C. psammophila are the only species of Cigclisula with fully immersed ooecia. Both species are distinguished by zooid size and colony size (smaller and unilamellar in C. psammophila), frontal shield (irregularly punctured in C. winstonae n. sp., marginally punctured in C. psammophila) and frontal and interzooidal avicularia (present in C. winstonae n. sp., absent in C. psammophila).
Distribution. Caribbean: Belize and Barbados.
