Diagnosis ( Denis 1923; Condé 1946; Bareth 2006)

Troglomorphic species. Antennae with 40–48 antennomeres; eight to nine complex olfactory chemoreceptors in cupuliform organ; protruding frontal process with tubercular setae. Pronotum with 1+1 ma, 4+4 la, 2+2 lp macrosetae; mesonotum with 1+1 ma, 2+2 la, 2+2 lp macrosetae; metanotum with 1+1 ma, 2+2 la, 2+2–1+1 lp macrosetae; thin, poorly barbed notal macrosetae; sparse long, thin, barbed notal clothing setae. No ventral tibial macrosetae; unequal claws with large lateral crests, posterior claw with a backward overhang. Urotergite III with 1+1 la macrosetae; urotergite IV with 1+1 la, 1+1 post macrosetae; urotergites V–VII with 1+1 la, 3+3–4+4 post macrosetae; urotergite VIII with 6+6 post macrosetae; abdominal segment IX with 8+8 post macrosetae; urosternite I with 11+11, urosternites II–VII with 9+9, urosternite VIII with 3+3 macrosetae. Male with a narrow area of glandular g 1 setae; subtrapezoidal appendages with an area of glandular a 2 setae; female with subcylindrical appendages with glandular a 1 setae. Spermatozoid fascicles 60–65 µm in diameter and 25–30 µm wide, wheels with 2½–3 turns of 650 µm long and 13 µm diameter filament.

Remarks

The study of one female from Puech Cave, Grands Causses, France (see Table S 2 in Supplementary Material) has allowed us to supplement the former description, including regarding the presence of only 1+1 lp metanotal macrosetae.

Habitat and distribution

Subterranean species, well-spread around the Grands Causses, where it is found in eight caves, living alongside the troglobite P. (P.) balsani .
