Distribution

Endemic to caves of the Algarve, the southernmost province of Portugal.

Remarks

The species is here fully illustrated ( Figs 33–34 ) to facilitate its recognition.

Ecological notes

Troglobiotic species. The specimens were mostly found inside the clay, which often covers their integument, an observation already pointed out by Vandel (1946). Some individuals were also found walking on cave walls and completely clean of clay. In the caves of the Algarve, this species occurs together with other remarkable troglobiotic species: the pseudoscorpions Titanobochica magna Zaragoza & Reboleira, 2010 and Lusoblothrus aenigmaticus Zaragoza & Reboleira, 2012 ; the spiders Harpactea stalitoides Ribera, 1993 and Teloleptoneta synthetica Machado, 1951 ; the millipedes Boreviulisoma barrocalense Reboleira & Enghoff, 2013 , Acipes machadoi Enghoff & Reboleira, 2013 , and A. bifillum Enghoff & Reboleira, 2013 ; the campodeid Litocampa mendesi Sendra & Reboleira, 2010 ; and the giant thysanuran Squamatinia algharbica Mendes & Reboleira, 2012 ( Reboleira et al. 2010c, 2012 a, 2012b; Reboleira & Enghoff 2013; Enghoff & Reboleira 2013b).
