Dimensions. Diameter of corallites: 1–1.8 mm; in areas of intense budding the diameter is around 0.8 mm; distance of corallite centers: 1.2– 2 mm, in areas of intense budding the distance is around 0.8 mm; septa/corallite: 12 (6s1 + 6s2); costae/corallite: 12 and higher.

Description. Small massive to knobby colony; corallites circular to subcircular in outline, regularly disposed over the colony; costosepta developed in 2 complete cycles in 6 systems, regularly alternating in length and thickness; number of costae is equal to or slightly larger than number of septa; columella absent but in a small number of corallites trabecular extensions of axial ends of septa reach corallite center where they might fuse, forming a pseudo-columella.

Type locality of species. Upper Jurassic (Tithonian) of Spain (La Querola) .

Distribution. Upper Jurassic of Armenia and Japan, Oxfordian of Germany and France, upper Oxfordian of Romania, Oxfordian–Kimmeridgian of Slovenia, lower Kimmeridgian of Romania, Kimmeridgian–Tithonian of Spain, Tithonian of Portugal, Tithonian–lower Berriasian of the Czech Republic and Poland, lower Valanginian of northeastern Switzerland (Vitznau Marl, Wart; new material this paper).

Material. NMSG Coll. PK–02.10.20f; –02.10.23d (= 02.10.29d); –02.10.27b; –02.10.28c and 28d; –02.10.29f; –02.10.30d; –02.10.32b.

Remarks. In Adelocoenia parvistella , auriculae are present which clearly distinguishes it from genera such as Cyathophora (including its junior synonym Cryptocoenia ). Tis represents an important fact, since Alloiteau (1958) also erected a species Cryptocoenia parvistella , using material from the Cretaceous of Madagascar (MNHN.F.M05039; and thin sections). Because the latter is here considered to belong to Cyathophora , the species is not a junior homonym.

Some of the specimens from the Jurassic of Iran assigned to this species A. slovenic a by Pandey and Fürsich (2003, p. 27), are considered as Solenocoenia (such as material shown on their pl. 6, Fig. 5 View Fig ). In addition, it should be noted that these authors place within A. slovenica material having dimensions that significantly differ from A. slovenica (e.g., specimen SNSB-BSPG 1999 VIII 874: corallite diameter: 1.5–2.3 mm; and specimen SNSB-BSPG 1999 VIII 1085: corallite diameter: 1.5–2.6 mm). Te consequence of such a wide grouping would be a much wider stratigraphic range for this species.
