Comments

This is an epigean species. Its habitat consists of wooded areas of medium or low altitudes. Vandel (1962) indicates a maximum altitude of 1800 m at Alpujarra ( Granada, Spain), which is close to the 1650 m site (at Sierra de las Nieves) where a female examined by us was captured. Vandel (1962) considers that the presence of the species in caves, as in Algeria, is related to the destruction of the surrounding woodland, that would be its natural habitat. Nonetheless, in the Iberian Peninsula, E. caelata is also found in caves. There are 21 mentions to cavities or caves, among the study material and cited bibliography, though only one of those is located in the North of the Iberian Peninsula (Cueva del Teleférico, Carranza, Vizcaya; Vivar et al. 1984), even in areas with preserved plant cover. Cifuentes et al. (2021) also mentioned the species in the Mesovoid Shallow Substratum – MSS ( Juberthie et al. 1980). The known distribution in the Iberian Peninsula ( Fig. 1A ) shows its abundant presence in the western part of the peninsula, suggesting larger populations from Lisbon ( Portugal) to Galicia ( Spain), and subsequent colonization of the east mountain ranges, reaching the Pyrenees, with the most eastern distribution point in Garralda (Navarra). In the south of the Iberian Peninsula, the distribution reaches the province of Almería, but is limited to areas of high environmental humidity (Paterna del Río, Alpujarra; Vandel 1953) or the MSS at Almería, as already mentioned, or in caves. In the centre, its colonization is very modest and always along mountain ranges. The most important factors that seem to be limiting its distribution are climatic, namely temperature and humidity. The lower temperatures in the peninsular centre and Pyrenees, appear to have stopped its progression to the east, and the high temperatures and low humidity, typical of the Mediterranean, have done the same from Almería to Catalonia. This species has been figured several times before, but to allow an easier comparison with the other species from the Iberian Peninsula from the genus, some figures are also provided ( Fig. 2A–C ).

The species is recorded for the first time in the Portuguese districts of Beja, Bragança and Setúbal and the Spanish provinces of Burgos and Cáceres.
