Candidula arrabidensis (Holyoak & Holyoak, 2014) Xeroplexa arrabidensis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.

[1] [2] The species epithet arrabidensis is an adjective derived from the type locality Serra da Arrábida.

Umbilicus moderately wide, symmetrical, deep, exposing upper whorls, usually slightly overlapped by reflected peristome.

Ground-colour pale brown throughout, or whitish beneath; upperside nearly always with brown to blackish-brown markings that are very variable in extent, but form sharply defined bands on only a minority of shells, consisting instead of interrupted bands or rows of irregular blotches, often with whitish rib crests; underside also with very variable dark markings, often in several thin interrupted bands; underside some- times mainly dark brown.

[3] Endemic to Portugal, where mainly restricted to rocky limestone habitats in Estremadura (Sétubal District) extending from Serra da Arrábida westwards to near Cabo Espichel.
