Material examined. NIWA 132737, NIWA Stn U 582, 31.8617º S, 172.4333º E, Three Kings Ridge, 790 m, collected 5 February 1988. Description. Colony erect, comprising three stems not> 7 mm in length, very slender, 4-sided, tapering proximally (W, 147–399 μm). Zooids arranged back to back in alternating pairs, hence 4 longitudinal series. Autozooidal cystids highly elongate-hexagonal, sometimes with rounded distal margins and lateral walls of whorled zooid pairs abutting or not (ZL, 632–880 μm; ZW, 343–364 μm; ratio 2). Cryptocystal surface evenly granular except for area proximal to opesia where granules are sparse to absent; cryptocystal ridges unusually merging into lateral zooid margins distally, continuous and rounded proximally. Lowest part of frontal cryptocyst immediately proximal to opesia. Opesia wider than long (OpL, 109–117 μm; OpW, 142–158 μm; ratio 0.75), rim scarcely raised, smooth or weakly and irregularly beaded where granules occur, centre of proximal margin upturned as conspicuous proximal rectangular lip with opesiular indentations either side; no visible condyles. Avicularia and ovicells not seen. Presumed ancestrular zooid flanked by larger latero-abfrontal pair, all three tapering to narrow point with tiny rootlet pores. Up to 4 paired zooid whorls distal to ancestrula with paired foramina where opesiular indentations used to be; proximal to these foramina, whorls closest to ancestrula have partial overgrowth of calcification, creating large opening for rootlet.
