Differential diagnosis

See under Dicharax duoculmen .

Remarks

Based on the spiral striae visible on the protoconch of the syntype, this species has been classified in Metalycaeus (see Páll-Gergely et al. 2020). Re-examination of that syntype revealed that those spiral striae are parts of lower shell layers; therefore, those are not homologous with those of species of Metalycaeus , which are raised striae. Furthermore, additional, fresh shells collected at Kalek-Rottung Road clearly lack spiral striation, showing that this is a species of Dicharax . Dicharax magnificus is the type species of Raptomphalus Godwin-Austen, 1914, and as a consequence, that taxon is a synonym of Dicharax (instead of Metalycaeus ).
