Dimensions. d=7.5–8.3 mm; s=48; h=7.5 mm

Description. Conical with pointed base; circular in outline; costosepta arranged in 4 cycles in 6 systems.

Remarks. Filkorn (1994, p. 47 and 61) described the forms Conocyathus felixi and Alveolocyathus nordenskjoeldi . Later, Cairns (1997, p. 20) united these two forms, considering Conocyathus felixi as the junior synonym. However, because the latter was established 14 pages before A. nordenskjoeldi , it has to be considered the senior synonym. The validity of A. nordenskjoeldi as the type species of the genus Alveolocyathus is not affected by its position as a junior synonym (ICZN 67.1.2).

Type locality of species. Maastrichtian of Seymour Island (Antarctic Peninsula) .

Distribution. Maastrichtian of Seymour Island (Antarctic Peninsula).
