Diagnosis ( Denis 1923; Condé 1947a, 1959; Silvestri 1947; Bareth 1968)

Troglomorphic species. Antennae with 28–36 antennomeres; abundant sheet-shaped olfactory chemoreceptors in cupuliform organ; protruding frontal process with tubercular setae. Pronotum with 1+1 ma, 3+3–4+4 la, 2+2 lp macrosetae; mesonotum with 1+1 la, 2+2 (3+2) lp macrosetae; metanotum with 2+2 lp macrosetae; long, barbed notal macrosetae; abundant barbed notal clothing setae. No ventral tibial macrosetae; unequal claws (1.35) with large lateral crests, posterior claw with a backward overhang. Urotergite IV with 0+0–1+1 la macrosetae; urotergites V–VII with 1+1 la, 4+4 post macrosetae; urotergite VIII with 5+5–6+6 post macrosetae; abdominal segment IX with 8+8–9+9 (9+10) post macrosetae; urosternite I with 11+1+11–15+15 (15+16), urosternites II–VII with 11+11– 14+14, urosternite VIII with 2+2–4+4 macrosetae. Male without glandular g 1 setae, thick subcylindrical appendages without glandular a 2 setae; female with subcylindrical appendages without glandular a 2 setae.

Remarks

The new material studied (see Table S 2 View Table 2 in Supplementary Material) allowed the addition of minor taxonomic details revealed by SEM microscopy.The epicuticle, apparently smooth in optical microscopy, shows a subtle reticulate surface ( Figs 166, 168 View Figs 163–168 ) covered by well-barbed clothing setae ( Figs 167–168 View Figs 163–168 ). The macrosetae are also well barbed, but the multi-barbed urosternal macrosetae ( Figs 169–170 View Figs 169–174 ) are remarkable. The gouge sensilla are abundant and as long as 28 µm, with transversal stripes in a V shape ( Figs 161–162 View Figs 157–162 ). The cupuliform organ has a narrow hole that does not allow an adequate observation of the olfactory chemoreceptors; however, these can be described under the optical microscope as having a multiple laminal shape and under SEM as a central structure with a pronounced terminal pore, semiradially and irregularly folded ( Figs 157–160 View Figs 157–162 ). The protruding frontal process with tubercular setae is clearly visible under SEM ( Figs 163–165 View Figs 163–168 ). Claws have well-developed lateral crests with a complex, grooved ventral surface ( Figs 171–174 View Figs 169–174 ). The completely barbed abundant macrosetae and setae cover the entire surface of the sternites ( Figs 169–170 View Figs 169–174 ). The entire length of the stylar setae is totally covered by barbs ( Figs 177–178 View Figs 175–180 ) and the eversible vesicles are large ( Fig. 179 View Figs 175–180 ). Males have large subcylindrical appendages with a large area of glandular a 1 setae ( Figs 175–176, 180 View Figs 175–180 ).
