Areospora was established with Areospora rohanae as the type species. Furthermore, the phylogenetic and morphological distinction from other diverse parasite phylum, therefore established a new genus under new family Areosporiidae to accommodate this parasite species (Stentiford et al. 2014). Merogonal and sporoogonal stages, in accordance with the generic description for Areospora, are found within the phagocytes and connective tissue cells of lithodid crabs. Parasite life stages can be enclosed within a specialized parasitophorous vacuole (SPV). The early sporogony is characterized by a distinctive rosette-like structure that is confined within the SPV. Rosettes comprise 8 pre-sporonts. The transition from rosette-like sporonts to early sporoblasts is characterized by the formation of spore-extrusion precursors and the migration of tubular bristles to the surface of the pre-sporoblast exospore layer, monokaryotic spores, adorned with unique bristles (Stentiford et al. 2014).
