This species is specifically endemic to the Iberian Peninsula, with its natural range concentrated in the southwestern regions. It is found primarily in southern Portugal and extends into the Spanish autonomous communities of Extremadura and western Andalusia.
Physical Characteristics
Blanus mariae is characterized by its distinctive coloration, which can range from a pale pink to a dark, brilliant purple. A notable feature is the presence of a reticulate pattern across its body, created by the inter-segmental sutures. The average snout-vent length for this species is approximately 175 mm (6.9 inches). As a fossorial species, it is adapted for a life spent underground.
Taxonomy and Etymology
This species is recognized as forming a cryptic species complex with Blanus cinereus, indicating a close evolutionary relationship that can make differentiation challenging. The specific name, mariae, was chosen in honor of Maria del Rosario Aguilar Tortajada, who was the grandmother of Eva María Albert, one of the scientists credited with describing this species. The research describing Blanus mariae was published in 2009, highlighting its status as a newly identified species within the Blanus genus.
