Proprioseiospsis pariquerassuensis n. sp.

(Figures 9–13)

Diagnosis. Females with dorsal shield mostly smooth, with few anterolateral reticula; z 2 and z 4 similar in length, both much shorter than the distances between their bases and the bases of the respective subsequent setae; j 3 about half as long as j 1; s 4 about 20 % shorter than Z 4, which in turn is about 10 % shorter than Z 5; sternal, genital and ventrianal shields reticulate; ventrianal shield pentagonal; calyx of spermatheca bell-shaped to saccular.

Specimens examined. Holotype female from Aciotis brachybotria (DC.) Triana, Pariquera-Açu, State of São Paulo, 24 October 2002 and a paratype female from Crepis japonica (L.) Benth., Pariquera-Açu, State of São Paulo, 24 October 2002, L.P.M. Machado coll.; deposited at ESALQ-USP.

Description. Female (n= 2). Figures 9–13.

Dorsum. Dorsal shield mostly smooth, with few anterolateral reticula, with nine pairs of distinguishable lyrifissures and five pairs of pores, 382–390 long and 252–255 wide. Setae j 1 31, j 3 17, j 4 5–6, j 5 5, j 6 6, J 5 8, z 2 7–8, z 4 8–9, z 5 5, Z 1 8, Z 4 140–145, Z 5 152–157, s 4 120–130, S 2 8 –9, S 4 9 –10, S 5 9 –10, r 3 23, R 1 6–8. Setae smooth and pointed.

Venter. Sternal shield reticulate, with three pairs of setae and two pairs of lyrifissures; distances between St 1 - St 3 68–69, St 2 - St 2 76. Genital shield reticulate; distance between St 5 - St 5 71–72. Ventrianal shield pentagonal, reticulate, 131–136 long, 100–106 wide at level of ZV 2, 80–86 wide at anus level, with three pairs of pre-anal setae (JV 1, JV 2 and ZV 2); JV 4, JV 5, ZV 1 and ZV 3 on unsclerotised cuticle and a pair of elliptical pre-anal pores in transverse line with JV 2. Ventral setae smooth and pointed. Two pairs of metapodal plates present. Peritreme extending beyond level of j 1.

Chelicera. Movable cheliceral digit 30–32 long, with three teeth; fixed cheliceral digit 33–34 long, with 15–16 teeth; pilus dentilis indistinguishable.

Spermatheca. Calyx bell-shaped to saccular, 11–13 long; atrium almost indistinguishable.

Leg macrosetae. Sge I 34–39, Sge II 36–40, Sge III 39–40, Sti III 29–33, Sge IV 88–90, Sti IV 71–75, St IV 84– 92, all pointed. Chaetotaxy: genu II 1–2 / 1, 2 / 0–1 genu III 1–2 / 1, 2 / 0–1.

Male. Unknown.

Etymology. The name pariquerassuensis is a compound of pariquerassu (from Pariquera-Açu) and ensis (Latin suffix denoting place of origin), referring to the type-locality of the species.

Remarks. Proprioseiopsis pariquerassuensis n. sp. belongs to the peruvianus species group, but it is also similar to the subgroup belizensis of the belizensis species group (Chant & McMurtry, 2007). This new species is similar to Proprioseiopsis miconiae Moraes & Mesa, 1991 and Proprioseiopsis caliensis Moraes & Mesa, 1988 . Proprioseiopsis miconiae differs from this new species by having j 3 longer (36) and the following setae shorter: Z 4, Z 5 and s 4 (all measuring 84 in P. miconiae ). Proprioseiopsis caliensis differs from this new species by having j 3 and z 4 longer [37 (34–41) and 16 (12–19) respectively] and Z 4 and Z 5 shorter[90 (82–94) and 84 (79–91) respectively].
