Justification
Zaluzianskya regalis is a range-restricted species, with an extent of occurrence (EOO) of 84 km². It is locally common, but a localized habitat specialist. It has no severe threats and is therefore not suspected to be in danger of extinction. It is therefore listed under the IUCN 3.1 Criteria, globally, as Least Concern but is nationally categorised as Rare.
