Orifice with 3‒5 (mostly three) jointed oral spines; proximal rim smooth, inner distal margin minutely denticulated. Ascopore non-reticulate, crescentic, denticulate, set within small raised gymnocystal area. Avicularia single, sparse, not found on every zooid, set some distance from ascopore. Ovicell surface like that of frontal shield but with few or no pseudopores apically; proximofrontal margin of ooecium with smooth raised band of calcification; some zooids with broad bridge of calcification embracing orifice distal to ascopore, the tip of an oral spine sometimes showing on each side inside its rim. Ancestrula tatiform with 11 spines.

. Colony colour whitish-transparent. Zooids subhexagonal, widest about midlength, interzooidal boundaries in furrows with thin, slight edges of gymnocyst visible in places [ZL 286‒407 (350), n = 20; ZW 192‒446 (275), n = 20]. Frontal shield pustulose, very sparsely pseudoporous (12‒18 pores in zone of astogenetic repetition), pores simple. Orifice transversely D-shaped with straight to slightly concave proximal margin; proximal smooth and non-denticulated, but inner face of distal oral arch weakly denticulate [OrL 43‒61 (53), n = 20; OrW 64‒100 (81), n = 20]. Typically three basally articulated oral spines, 4‒5 near colony origin, joints not dark. Ascopore transversely bean-shaped and weakly denticulate, set within the distal half of a slightly raised, smooth, shallow gymnocystal area; area between ascopore and proximal margin of orifice relatively smooth with a few tiny pustules. Avicularia sparse, single, not on every zooid, produced from an areolar-septular pore, not a pore-chamber; with complete crossbar, rostrum triangular overall with concave sides, the distal tip broadly rounded, open, channel-like. Mandible setiform, stilettolike with expanded triangular base [AvL 52‒69 (61), n = 7; AvW 43‒54 (48), n = 7; AvML 118‒147 (128), n = 7]; open mandible not reaching to opposite margin of zooid. Ovicell conspicuous, globular, ooecial surface pustulose like the frontal shield with a few peripheral pseudopores; strongly personate, but not in all zooids, with a broad bridge of calcification embracing the orifice distal to the ascopore, the tip of an oral spine showing on each side inside its rim in some zooids [OvL 168‒216 (190), n = 9; OvW 188‒215 (199), n = 9]. Embryos reddish. Interzooidal communications comprising well-developed basal pore-chambers, 1‒2 on each lateral wall and 2‒3 small such chambers below and around the orifice. Ancestrula tatiform, with elongate-oval opesia bordered by 11 spines; gymnocyst smooth (AnL 262‒280 (271), n = 2; AnW 180‒228 (204), n = 2). Two daughter zooids produced, each in a distolateral position.

We closely examined three fertile colonies at 1.88‒2.00 mm maximum length. The largest of the three had 31 zooids (8 frontally broken), of which 11 were ovicellate and three bore an avicularium. A colony of 26 zooids had seven that were ovicellate and four bore an avicularium. The third colony had 25 zooids, of which seven bore ovicells and four had an avicularium. Thus c. 26‒28% of the zooids in a sexually reproducing colony are actively producing larvae.
