( Figure 5 View Figure 5 )

Material examined— Brazil. Male, syntype, Rio Grande do Sul, Brasilien, Prof. v. Iherring coll., slide 822 ( MfN). Bolivia. 1/11/0, pond Hotel Flora y Fauna, 3 km SE of Buena Vista, Bolivia, 17°29.949 S 63°38.152 W, 10-iii-1999, leg. D. Tempelman.

Description — Male: Idiosoma dorsally 761 long and 425 wide, ventrally 773 long. Distance anterior idiosoma margin – dorsal shield 144. Gonopore 42 long, genital field 284 wide. Length of P1-5: 24, 48, 27, 58, 36.

Female: Idiosoma dorsally 761 long and 632 wide, ventrally 753 long. Dorsal shield complete, 583 long and 458 wide.

Remarks — The slide with the syntype is partly dried, the type is squashed and positioned laterally. Only the cauda and part of the dorsal shield are well visible. Lundblad (1944) gave a very complete description of the species, and therefore only some measurements are given and some illustrations are presented. There is only one small difference with the description of Lundblad (1944) and the male specimen of the present paper in the configuration of the setae on the ventral side of the cauda. Lundblad illustrated the setae associated with Vgl-3 further posteriorly.
