Diagnosis ( Sendra et al. 2004)

Troglomorphic species. Antennae with 39 antennomeres; 12 very complex olfactory chemoreceptors in a large cupuliform organ; protruding frontal process with tubercular setae. Pronotum with 1+1 ma, 2+2 la, 2+2 lp macrosetae; mesonotum 1+1 with ma, 2+2 lp macrosetae; metanotum without macrosetae; short, barbed notal macrosetae except pronotal lp; sparse smooth clothing setae. Two ventral tibial macrosetae; slightly unequal claws (1.16) with large lateral crests, posterior claw with a short backward overhang. Urotergites V–VI with 1+1 la, 1+1 post macrosetae; urotergite VII with 1+1 la, 2+2–3+3 post macrosetae; urotergite VIII with 5+5–6+6 post macrosetae; abdominal segment IX with 8+8 post macrosetae; urosternite I with 8+8, urosternites II–VII with 5+5, urosternite VIII with 2+2 macrosetae. Male with a narrow area of glandular g 1 setae, with subcylindrical appendages similar to those of female, with glandular a 1 setae.

Remarks

SEM observations have shown several taxonomical features to complete the original description ( Sendra et al. 2004). Each olfactory chemoreceptor shows a spiral fold with a central cylindrical structure, all with a multiporous surface, all tightly open to the exterior through a small opening ( Figs 12, 14–15 ), surrounded by tiny coniform sensilla ( Figs 12–13 ) that are present in the whorl of thin gouge sensilla on each medial and distal antennomere ( Figs 16–17 ). Tibia longer than femur and tarsus ( Fig. 18 ). Pretarsus with subequal claws with large lateral crests, the claws carved by longitudinal ridges and a micro-tuberculated surface ( Figs 20, 22–23 ). Lateral process smooth, with several thin basal barbs ( Figs 22–23 ). Stylar setae with abundant barbs ( Fig. 21 ). Male with subcylindrical appendages with only glandular a 1 setae and a narrow area of glandular g 1 seate ( Fig. 19 ).

Habitat and distribution

Subterranean species known only from Nerja Cave, a touristic cave in the internal zone of the Baetic Mountain Range, southern Iberian Peninsula.
