Proprioseiospsis pariquerassuensis n. sp.

(Figures 9–13)

Diagnosis. Females with dorsal shield mostly smooth, with few anterolateral reticula; z2 and z4 similar in length, both much shorter than the distances between their bases and the bases of the respective subsequent setae; j3 about half as long as j1; s4 about 20% shorter than Z4, which in turn is about 10% shorter than Z5; 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 j1 31, j3 17, j4 5–6, j5 5, j6 6, J5 8, z2 7–8, z4 8–9, z5 5, Z1 8, Z4 140–145, Z5 152–157, s4 120–130, S2 8 –9, S 4 9 –10, S 5 9 –10, r3 23, R1 6–8. Setae smooth and pointed.

Venter. Sternal shield reticulate, with three pairs of setae and two pairs of lyrifissures; distances between St1 - St3 68–69, St2 - St2 76. Genital shield reticulate; distance between St5 - St5 71–72. Ventrianal shield pentagonal, reticulate, 131–136 long, 100–106 wide at level of ZV2, 80–86 wide at anus level, with three pairs of pre-anal setae (JV1, JV2 and ZV2); JV4, JV5, ZV1 and ZV3 on unsclerotised cuticle and a pair of elliptical pre-anal pores in transverse line with JV2. Ventral setae smooth and pointed. Two pairs of metapodal plates present. Peritreme extending beyond level of j1.

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 j3 longer (36) and the following setae shorter: Z4, Z5 and s4 (all measuring 84 in P. miconiae ). Proprioseiopsis caliensis differs from this new species by having j3 and z4 longer [37 (34–41) and 16 (12–19) respectively] and Z4 and Z5 shorter[90 (82–94) and 84 (79–91) respectively].
