This distinctive endemic hippothoid is easily recognised by its rounded distally projecting hollow suboral umbo, which is flanked by a similar projection either side of the orifice (Figs 11D, F; 12). This arrangement, i.e. an orifice flanked by three prominent umbones—is also seen in the ancestrula, except that the lateral pair of umbones is produced not by the ancestrula, but by the first pair of daughter zooids (Fig. 11E). As in A. buskiana, the ancestrula has a pair of large distolateral pore-chambers that bud the first daughter zooids. These do not touch; however a small proximal part of the median zooid that is budded between them just touches the ancestrular rim. Zooids are almost parallel-sided but tend to narrow a little towards the generally truncate proximal margin. Female zooids (cystids) are typically shorter and wider than autozooids, with ooecia that are wider still. Dimorphic combined maternal apertures lack flanking umbones and have a tiny, variable sinus that rages from a broad V to a small U (a mere nick) in shape.
