Adeonella ornatissima (Stoliczka, 1862) (Fig. 3 B-D)

Eschara (Escharifora) ornatissima Stoliczka, 1862: 86, pl. 2, fig. 7.

Adeonella ornatissima – Zágoršek 2003: 152, pl. 19, fig. 2 (cum syn.).

MATERIAL EXAMINED. — Two syntypes registered as 2010/0259/0010. Ŋe chosen lectotype (designated here) corresponds with Stoliczka’s illustration (1862: pl. 2, fig. 7) and is depicted in Figure 3D herein.

DIAGNOSIS. — Colony erect, flat, multiserial, bifurcating, with 8-10 longitudinal rows of autozooecia. Autozooecia at colony margin can be more than twice as long as those in colony centre. Frontal shield without granulations, knobbly, perforated by marginal areolar pores; lateral tubercles sometimes developing when secondary calcification occurs; frontal area relatively narrow in zooecia located in middle part of colony. Orifice oval to suborbicular with broad poster. Lateral-oral pair of avicularia small, circular, often fusing as bridge across aperture in older parts of colony. Secondary calcification often expressed as well-developed tubercles situated usually in corners of zooecia.

REMARKS

Adeonella ornatissima differs from Adeonella mortisaga (Stoliczka, 1862), n. comb. in having shorter autozooecia with a knobbly frontal shield and oral avicularia that may fuse across the aperture.
