Adeonella mortisaga (Stoliczka, 1862), n. comb. (Fig. 3 E-F)

Eschara (Escharifora) mortisaga Stoliczka, 1862: 86, pl. 2, fig. 6.

MATERIAL EXAMINED. — Two syntypes registered as 1859/0026/0137. Ŋe chosen lectotype (designated here) corresponds with Stoliczka’s illustration (1862: pl. 2, fig. 6) and is depicted as Figure 3E herein.

DIAGNOSIS. — Colony erect, multiserial. Autozooecia may be rhomboidal in central part of colony, more elongate on colony margin. Frontal shield granular, perforated by marginal areolar-septular pores. Orifice with transversely D-shaped anter and narrow sinus. Adventitious avicularia small, paired, one on either side suborally. Maternal zooecia up to more than twice as wide distally as autozooecia, with smooth ooecial margin much wider than long, showing beneath distal secondary calcification. Secondary zooecial calcification often accompanied by tubercles situated usually in margins and/or on frontal shield including loci of suboral avicularia.

REMARKS

Ŋis species differs from A. ornatissima in having very large maternal zooecia, longer autozooecia with granular frontal shields, and suboral (not lateral-oral) avicularia.It is similar also to Adeonella minor (Reuss, 1869) which, however, never has such large brooding zooids and the apertural sinus is less prominent.
