Comments

This small epigean species, endemic to Portugal ( Fig. 1C ), is also known from caves and MSS ( Reboleira et al. 2015). This species is much less known than E. caelata . Although Cruz (1991) and Reboleira et al. (2015) have already illustrated it, we consider useful to provide some figures of the species ( Fig. 2D–F ), some from anatomical aspects not yet described, valuable to compare with other species of the genus.

The species is recorded for the first time in Coimbra district.
