A second blind species of the genus Zariquieya Jeannel, 1924, Z. boumortensis n. sp., is described from the southern slope of central spanish Pyrenees (Lleida, Spain). Morphological structure of the new species, especially male and female genitalia as well as the external morphology suggests that this carabid beetle should be included in the genus Zariquieya, created for a single species endemic of eastern Spanish Pyrenees. The new species is morphologically distinct from Z. troglodytes Jeannel, 1924 by numerous characters like maxillary palpus glabrous, pronotum more transverse, frontal impressions lighter, and elytra with flat disk without strong lateral and apical declivity. A key for identification of Pyrenean Molopina is given, and ecology and biogeographical considerations are detailed, including distribution map of Pyrenean hypogean Molopina.
