Plusiocampa baetica Sendra in Sendra et al., 2004: 114, figs 1–4, tables 1–4.

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.
