Pseudohomoeomma fasciatum Mello­Leitão, 1930: 57 , figs 5–7. Lectotype male (here designated) and paralectotype female from Cuminá River, Pará State, Brazil, G. Cruls & A. Sampaio, MNRJ, examined; Bücherl, 1957: 391, figs 38–38a; Bücherl et al. 1971: 118, figs 35–37; Schiapelli & Gerschman 1973: 67; Smith 1986: 97, fig. 98h; 1987: 97, fig. 98h.

Cyriocosmus elegans : (in part) Schiapelli & Gerschman 1973: 67 (synonymy, here rejected); Pérez­ Miles 1998: 100.

Diagnosis: The female differs from all the other species, except C. fernandoi new species and C. elegans , by the presence of four clear stripes on each side of the dorsal abdomen ( Fig. 44 ). It can be distinguished from C. fernandoi new species and C. elegans by the clear central patch covering more than 80% of the dorsal abdominal area. The male can be distinguished from C. nogueira­netoi new species, C. fernandoi new species and C. chicoi by having a retrolateral field of spiniform hair on the palpal tibia. It differs from C. ritae by not having a longitudinal dark band on the ventral abdomen and from C. sellatus by having a striped dorsal abdominal pattern. It can be distinguished from C. blenginii by the paraembolic apophysis originating prolaterally to the embolus ( Figs 9, 10 ). It can be distinguished from other species by having a long paraembolic apophysis.

Distribution: Known only from type locality, Cuminá River, Pará, Brazil ( Fig. 56 )
