Redescription (based on Chevrizov 1978)
Under optical microscope, one can see a smooth cuticle covered by thin and smooth clothing setae. The more complete antennae is apparently regenerated and it has 23 antennomeres in the 5.4 mm adult from Grotte du Pylone; the third antennomere has a thick sensillum in ventral position (d–e macrosetae) (Fig. 49). The small and pointed frontal process has one long and smooth anterior macroseta and two shorter posterior macrosetae; there are three smooth macrosetae along each side of the insertion line of the antennomere and smooth x setae with similar length, ratios of a / i / p / x are 14/19/14/ 19 in the holotype, respectively. The labial palps have a large thick sensilla (Fig. 50). Pronotum with 1+1 ma, 2+2 la, 2+2 lp 1,3, mesonotum with 1+1 ma, 2+2 (2+1) la, 2+2 lp 2,3, 1+1 mp, and metanotum with 1+1 ma, 0–1+1 la, 2+2 lp 2,3, 1+1 mp macrosetae; long and thin notal macrosetae with thin barbs along their distal three-fourths; marginal setae are long and barbed as the macrosetae. Metathoracic legs reach the posterior border of the V–VI abdominal segment; femora has two long, barbed dorsal macrosetae and one ventral macroseta, while the tibia has one short ventral macroseta, a few distal barbs, and calcars with several long barbs; the tarsus has two rows of smooth ventral setae slightly thicker than the clothing setae, and in the distal portion: three long, smooth dorsal setae, one ventral seta and one distal seta; the pretarsus is without lateral processes, with unequal elbowed claws and large lateral crests. Urotergite I–II with 1+1 post 1; urotergite III with 2+2 post 1,2; urotergites IV–VII with 4+4 post 1–4; urotegite VIII with 5+5 post 1–5 and abdominal segment IX 7+7 with post, macrosetae are long with barbs along their distal three-fourths. Urosternite I with 6+6, urosternites II–VII with 4+4 and urosternite VIII with 1+1 macrosetae; urosternal macrosetae shorter than urotergal macrosetae with long barbs; smooth stylar setae. Appendages of the first urosternite (female) with large, short and subcylindrical appendages, each with apical field of glandular a 1 setae. The most complete cercus is regenerated and it has six primary articles and a basal article, which are covered by several whorls of barbed macrosetae with long barbs along the third distal and a few whorls of smooth setae.
