Additional material examined: IBSP 11032, Brazil , Rondonia, Monte Negro , 1 female , R. Bertani & P. I. Silva Junior, July 2002 . Diagnosis: Females can be distinguished from all species, except C . nogueira­netoi new species, by having a pattern on the abdomen with five clear stripes on each side ( Fig. 47 ). It can be distinguished from C . nogueira­netoi new species by having a spiral spermathecae with caliciform seminal receptacle ( Fig. 36 ). Males differ from C. ritae and C. sellatus by the absence of a retrolateral field of spiniform setae on the cymbium and from C. blenginii and C. fasciatus by the absence of spiniform setae on the retrolateral palpal tibia. From C. fernandoi new species , it differs by having a smooth prolateral superior keel ( Figs 15, 16 ) and by the metatarsus I contacting the retrolateral side of the retrolateral branch of the tibial apophysis when folded ( Fig. 30 ). It can be distinguished from C. nogueira­netoi new species by the cephalothorax having a blackish area covering the cephalic region and a large part of thoracic region, as well as the abdominal color pattern having the anterior dark area entering the lighter central area ( Fig. 47 ). Males can be distinguished from other species by having a long paraembolic apophysis. Distribution: Brazil : State of Rondonia ( Fig. 56 ).
