Description. FEMALE (7 specimens measured).

Dorsum. Dorsal shield mostly smooth, with a few anterolateral striae, 378 (362–392) long and 227 (212– 255) wide; j1 28 (25–30), j3 28 (25–30), j4 6 (5–7), j5 5 (4–6), j6 9 (6–7), J5 8 (7–9), z2 7 (7–8), z4 10 (9–12), z5 6 (5–6), Z1 10 (10–11), Z4 118 (105–130), Z5 120 (105–132), s4 103 (93–115), S2 10 (10–12), S4 10 (10– 12), S5 10 (9–11), r3 27 (26–28), R1 9 (8–9). All setae smooth, except Z4 and Z5, serrate.

Ve n t e r. Sternal and genital shields reticulated, distances between st1-st3 71 (70–73), st2-st2 79 (77–81) and st5-st5 68 (67–70); ventri-anal shield pentagonal, striated anteriorly, transversally striated medially and smooth posteriorly, 131 (129–133) long, 107 (105–110) wide at level of ZV2 and 86 (83–90) wide at level of anus; JV5 92 (90–95).

Peritreme. Extending forward to level of j1.

Chelicera. Movable cheliceral digit 33 long, with 3 teeth; fixed cheliceral digit 32 (31–32) long, with 13 teeth.

Spermatheca. Calyx saccular, 11 (10–13) long; atrium punctated, not distinctly winder than adjacent section of major duct.

Legs. Sge I 36 (33–40), Sge II 34 (30–38), Sge III 33 (30–36), Sti III 29, Sge IV 70 (60–80), Sti IV 59 (55–68), St IV 82 (70–90); all macrosetae sharp-tipped. Chaetotaxy: genu II 2-2 /0-2/0-1; genu III 1-2 /1-2/0-1.

Etymology. This species is named in honor of “Instituto Biológico de São Paulo”, a renowned Brazilian institution where the type specimens of this species were collected and which has contributed for many years to the development of agriculture in Brazil.

Remarks: This new species could be classified in the peruvianus species group ( Chant & McMurtry 2005b) by having a macroseta on genu I. However, it differs from the species listed by Chant & McMurtry (2005b) in this group by having an elongate dorsal shield. It resembles several species of the belizensis subgroup of the belizensis species group ( Chant & McMurtry 2005b), mainly Proprioseiopsis asetus (Chant) , P. caliensis (Moraes & Mesa) , P. mexicanus ( Garman) , P. miconiae (Moraes & Mesa) , P. lineatus (Wu & Lan) and P. weintraubi (Chant & Hansell) , by the similar lengths of the dorsal shield setae and macrosetae of leg IV, shape of dorsal and ventral shields, smooth texture of dorsal shield and, except P. asetus and P. mexicanus , shape of the spermatheca. However, the new species differs from the former four species by having seta j1 about as long as j3 (j3 distinctly longer than j 1 in those species). In addition, it differs from P. asetus and P. mexicanus by having calyx of spermatheca sacullar (cup-shaped in those species), from P. caliensis and P. miconiae by having setae s4, Z4 and Z5 about 1.4 times longer and sternal and genital shields distinctly more reticulated, and from P. lineatus and P. weintraubi by having sternal and genital shields reticulated and preanal pores mesad and transversely aligned with the bases of setae JV2 (sternal and genital shields smooth and pre-anal pores posterior and longitudinally aligned with the bases of setae JV 2 in those species).
