The monotypic genus Dasyatispora (Microsporidia, Protozoa) was introduced by Diamant et al. (2010)Dasyatispora levantinae, the type species of the genus was isolated from the Mediterranean common stingray Dasyatis pastinaca in Iskenderun Bay, Turkey. Disc muscle invasion by the parasite results in thin, spindle-shaped subcutaneous swellings that grow into large, elongated, tumor-like protuberances. These masses contained a yellowish-white caseous material made up of damaged host tissue and microsporidian sporophorous vesicles, which in turn contained sporonts, sporoblasts, and spores. The mature spore has a large posterior vacuole and a uni-nucleate sporoplasm. Sporophorous vesicles are slightly flattened spheres, measuring approximately 30 μm. Spores had an outer smooth surface and an oval form that was slightly longer.

According to phylogenetic analysis of SSU rRNA, ITS, and LSU rRNA, Dasyatispora belongs to the Pleistophoridae, and groups with species of Ovipleistophora (Ovipleistophora mirandellae) and Heterosporis (Heterosporis finki). However, the morphological characters, development, and host specificity raised this clade to a generic status and it differs distinctly from all reported genera including those belonging to Ovipleistophora and Heterosporis (Diamant et al. 2010)
