Celleporaria cylindrocystis Tilbrook, 2006: 145 , pl. 27D–F.
Figured material. RGM.1350559, early Pleistocene, Java; RGM.1350560, Holocene, UPGG 041, off South Sulawesi.
Description. Colony encrusting, multiserial, becoming multilaminar through frontal budding. Basal autozooids irregularly polygonal, distinct with shallow interzooidal furrows, longer than broad (mean L/W = 1.13); frontally budded autozooids irregularly arranged, erect, deep-bodied. Frontal shield convex, slightly nodular, with 6–8 irregularly spaced, subcircular areolar pores, 15–25 µm in diameter. Orifice subcircular with three tooth-like processes, squared or pointed, delineating asymmetrical pseudosinuses; condyles absent. Two distolateral, oral spine bases may occur, about 15 µm in diameter. Suboral avicularium small, elliptical, facing frontally, directed proximally, often placed at the apex of a raised cylindrical structure; crossbar complete. Interzooidal avicularia irregularly distributed, variable in size, spatulate or elliptical. Ooecium hood-like, broader than long, slightly nodular like the frontal shield, imperforate.
Remarks. A half-dozen fragments of Celleporaria cylindrocystis were found in our samples. This species was described for the first time from the Solomon Islands but specimens previously assigned to Celleporaria tridenticulata ( Busk, 1881) may belong to this species ( Tilbrook 2006). Celleporaria cylindrocystis is distinguished by the three tooth-like processes in the orifice, the presence of oral spines, and the suboral avicularium placed on a cylindrical cystid. The latter character is unique to this species in the genus Celleporaria ( Tilbrook 2006) . The Pleistocene specimens differ from the holotype specimen in having fewer marginal areolar pores.
