Type species
Hiiumoceras hiiuense gen. et sp. nov. Hiiumaa Island, Estonia; Pirgu Regional Stage.
Diagnosis
Small, strongly curved, exogastric cyrtocones with short body chamber; circular conch cross section; siphuncle at some distance from conch margin (subventral); ornamented with fine, directly transverse striae.
Etymology
Refers to Hiiumaa Island, the region of the type species of this genus.
Comparison
The genus is very similar to Ringoceras Strand, 1934, from the Bønsnes Formation, late Katian, Ringerike, Norway, from which it differs in having a circular conch cross section and in lacking the longitudinal ornamentation.
