The sp elements with denticles at the end of the external process taller than the cusp.

Porównanie

The evolution of the lineage of Histiodellla is well knownowing to descriptions by McHARGUE ( 1982) of its earlier part and by STOUGE ( 1984) of the later stages in the evolutionary development of denticulation. This allows very precise across- Iapetus correlation of the Late Arenig
strata containing this species . In Mójcza only the sp elements have been found but the apparatus was
reconstructed by STOUGE ( 1984) on the basis of a rich Newfoundland material.
