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. FIGURES 8–12 Proprioseiopsis biologicus sp. nov. 8–12. Female: 8. dorsal shield; 9. ventral idiosoma; 10. chelicera; 11. spermatheca; 12. Leg IV. 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).
