Redescription (based on Chevrizov 1978)

Under optical microscope it has a smooth cuticle covered by thin smooth clothing setae. Antennae are apparently intact with 23 antennomeres in the paratype, medial antennomeres 1.4 × as long as wide; third antennomere with a thick sensillum in ventral position (c–d macrosetae); last antennomere with at least eight olfactory chemoreceptors. Small and pointed frontal process has one long anterior smooth macrosetae and two shorter posterior macrosetae; there are three smooth macrosetae along each side of the line of insertion of antennomere and smooth x setae with a similar length, ratios of a / i / p / x are 20/23/22/23, respectively. Labial palps are large with thick sensilla. Pronotum with 1+1 ma, 3+3 (2+ 2 paratype) la, 2+2 lp 1,3 mesonotum with 1+1 ma, 3+3 (2+ 2 paratype) la, 2+2 lp 2,3, 1+1 (0+ 1 paratype) mp and metanotum with 1+1 ma, 2+2 lp, 1+1 mp macrosetae, long and thin notal macrosetae covered with thin barbs along their distal three-fourths; marginal setae are long and some of them are as long and barbed as the macrosetae. The metathoracic legs reach the posterior border of the VII abdominal segment; femora have two long barbed dorsal macrosetae and one ventral macrosetae. The tibia has one ventral short macrosetae, a few distal barbs, and calcars with several long barbs. The tarsus has two rows of smooth ventral setae, slightly thicker than clothing setae and on distal part: three long smooth dorsal setae and one ventral seta; the pretarsus has no lateral processes, with unequal elbowed claws, and with large lateral crests. Urotergite I with 1+1 post 1; urotergite II 1+2 (1+ 1 paratype) post 1,2; urotergite III 2+2 post 1,2; urotergites IV–VII 4+4 post 1–4; urotergite VIII 5+5 post 1–5 and abdominal segment IX 7+7 post, macrosetae long with barbs along three-fourths. Urosternite I with 5+5, urosternites II–VII 4+4, and urosternite VIII 1+1 macrosetae; urosternal macrosetae are shorter than urotergal macrosetae with long barbs; smooth stylar setae. First urosternite appendages (female) have large, short and subconical appendages, each with apical field with about fifty glandular a 1 setae.
