M. Mann; (ZMH) 1 specimen, PARAGUAY, Puerto Max, Paraguay river, 9-III-1905. Diagnosis. Prefemur of the ultimate pair of legs with three ventral spinous processes (Figure 1); femur and tibia each without ventral spinous process (Figure 2); femur and tibia each with a small cylindric process at ventral corner of distal end and tarsus 1 clavate (Figure 3). Tarsus 2 with 11 or 12 "pseudoarticles" . Tibia longer than or equal to femur. Tooth plates short, dentiform wider than long (Figure 4). Coxopleural process medium to short. Figures 1-4. 1 Tidops balzanii (IBSP 1559). Prefemur and femur of the ultimate leg showing ventral spinous processes of the prefemur. Lateral view 2 Tidops balzanii (IBSP 1559). Ultimate legs. Lateral view 3 Tidops balzanii (IBSP 1559). Ultimate legs. Ventral view 4 Tidops balzanii (IBSP 1559). Forcipules. Ventral view. Scale bar 1 mm. Remarks. The legs of Tidops balzanii are hirsute; articles of the ultimate legs are usually shorter than in the other three species of the genus. A specimen at the Zoologisches Museum Hamburg, Hamburg, Germany is labeled as "Type Mus. Turin, Argentina: Rio Apa, (C-VI-1903)" and was identified as Newportia balzanii . I am not sure if this specimen corresponds to the holotype of Newportia balzanii . Type locality. Rio Apa, Paraguay. Distribution. Brazil (Tocantins, Goias , Sao Paulo and Rio Grande do Sul), Bolivia (new record) and Paraguay.
