Key to species

1 Pale, depigmented subterranean species with reduced or absent eyes............................................. 2

- Coloured epigeic species with fully developed eyes.......................................................... 3

2 Eyes absent (Basque-Cantabrian Region, Spain and western part of the Pyrenees Mts., France). ♂ Cymbium rounded, embolus making about three turns around bulbus ( Fig. 4A ). ♀ Two pairs of small spermathecae far in front of the epigastric fold ( Fig. 5A )........................................................................................ mazarredoi

- Eyes reduced ( Great Britain, Germany, Switzerland, Czechia, Slovakia, Hungary and Romania). ♂ Cymbium conical, embolus making one turn around the bulbus ( Fig. 4B ). ♀ Loops of copulatory ducts are situated in front of the primary spermathecae situated near the epigastric fold. Secondary spermathecae are greatly reduced and hardly visible ( Fig. 5B ).... microphthalma

3 ♀ Vulva with large secondary spermathecae ( Fig. 5C ). Male palpal femur with five to six spines ventrally.......... candida

- ♀ Secondary spermathecae smaller or absent ( Figs. 5D, E ). Male palpal femur with three spines ventrally............... 4

4 It is not possible to distinguish the males of montana and difficilis . ♀ Epigyne: spermathecae are distinct and clearly visible. Vulva: primary spermathecae are separated by a space smaller than their diameter. Secondary spermathecae are clearly developed ( Fig. 5D )................................................................................. montana

- ♀ Epigyne: spermathecae are indistinct and barely visible. Vulva: primary spermathecae are separated by a space broader than their diameter, secondary spermathecae are greatly reduced and barely visible ( Fig. 5E )........................ difficilis
