Types

Female holotype ( MNHN 8102 , newly MNHN AR 12330 ), male allotype ( MNHN 8102 , newly MNHN AR 12331 ), immature male ( MNHN 8102 , newly MNHN AR 12332 ) from Brazil, Upper Amazonas , São Paulo de Olivença, Fonte Boa . Male allotype examined. The designation of the types follows Schiapelli and Gerschman de Pikelin (1973) and differs from the records in MNHN made by Gerschman de Pikelin and Schiapelli .

Diagnosis

The species can be distinguished from all other congeners by lacking the striped pattern on dorsal abdomen ( Figure 21c ) and by the black carapace with two pale and wide lateral stripes ( Figure 21a ), in combination with the yellowish longitudinal stripes on the dorsal face of the legs in females. The males have a long paraembolic apophysis and indistinct prolateral superior keel in palpal bulb ( Figures 21f , 26c, d , 32e, f ).

Distribution ( Figures 36 , 37 )

Known only from Brazil, Upper Amazonas, São Paulo de Olivença, Fonte Boa, and newly from Peru, Loreto, Yanamono, 80 km east of Iquitos.

Notes

All types are uniformly light brown due to the long-term preservation in alcohol. Simon (1889) mentioned in the original description that females of C. sellatus have yellowish longitudinal stripes on the dorsal faces of the legs and pointed out the presence of two pale and wide lateral stripes on the carapace as well. These traits are newly included in the diagnosis. It is supposed that the yellowish longitudinal stripes are present in males as well and are obviously much more distinct, as in males of other species with pale longitudinal stripes on the legs.
