Cyriocosmus blenginii Pérez­Miles, 1998

Figs 21–23 , 50

C. elegans : (in part) Schiapelli & Gerschman 1973: 68–69.

C. blenginii Pérez­Miles, 1998: 99 , figs 25–27. Holotype male, BMNH 1294.8.29.1, from Bolivia, Mamoré River, without further information, not examined. Female unknown.

Diagnosis: The male differs from C. nogueira­netoi new species, C. fernandoi new species and C. chicoi by the presence of a retrolateral field of spiniform hairs on the palpal tibia. It can be distinguished from C. ritae and C. sellatus by the absence of a retrolateral field of spiniform hairs on the cymbium and differs from C. fasciatus by the paraembolic apophysis originating dorsally to the embolus rather than prolaterally ( Figs 21, 22 ). It can be distinguished from other species by having a long paraembolic apophysis.

Distribution: known only from type locality, Mamoré River, northern border of Bolivia and Brazil ( Fig. 56 ).
