(Figures 41–45)
Diagnosis. Females with dorsal shield mostly reticulate, with a smooth band across region of insertion of Z4; s4 smooth, stout and pointed; J5, Z4 and Z5 serrate; other setae smooth; ventrianal shield pentagonal and smooth; calyx of spermatheca bell-shaped; macrosetae on legs I–IV, knob-tipped.
Specimens examined. Holotype female and two paratype females from Piptocarpha sp., Cananéia, State of São Paulo, 9 October 2001, L.V.F. Silva coll.; a paratype female from unidentified plant, Cananéia, State of São Paulo, 9 October 2001, L.V.F. Silva coll.; all deposited at ESALQ-USP. Three paratype females from Piptocarpha sp., Cananéia, State of São Paulo, 9 October 2001, L.V.F. Silva coll., deposited at DZSJRP.
Description. Female (n= 7). Figures 41–45.
Dorsum. Dorsal shield mostly reticulate, with a smooth band across region of insertion of Z4, with seven distinguishable pairs of lyrifissures and two pairs of pores, 382 (372–390) long and 209 (197–222) wide. Setae j1 27 (24–29), j3 33 (32–35), j4 12, j5 11 (11–12), j6 15 (14–16), J2 17 (15–21), J5 13 (12–13), z2 20 (18–21), z4 15 (15– 16), z5 10 (10–11), Z1 23, Z4 60 (57–60), Z5 91 (90–92), s4 53 (50–57), S2 38 (35–39), S4 21 (21–22), S5 19 (18– 23), r3 17 (16–18), R1 24 (23–25). Setae smooth and pointed, except for J5, Z4 and Z5, serrate and pointed; s4 stout.
Venter. Sternal shield smooth, except for few lateral lines, with three pairs of setae and two pairs of lyrifissures; distances between St1 - St3 66 (64–68), St2 - St2 71 (70–73). Genital shield smooth; distance between St5 - St5 74 (72– 77). Ventrianal shield pentagonal, smooth, 126 (122–129) long, 130 (128–134) wide at level of ZV 2, with three pairs of pre-anal setae (JV1, JV2 and ZV2); JV4, JV5, ZV1 and ZV3 on unsclerotised cuticle and a pair of pre-anal pores posteromediad of JV 2, slightly closer to each other than to JV2 of respective side. Ventral setae smooth and pointed. With two pairs of metapodal plates. Peritreme extending to level of j1.
Chelicera. Movable cheliceral digit 30 (27–32) long, with four teeth; fixed cheliceral digit 34 (32–35) long, with 11 teeth and a pilus dentilis.
Spermatheca. Calyx bell-shaped, 18 long; atrium vacuolate; base of major duct distinctly sclerotised.
Leg macrosetae. Sge I 36 (35–39), Sge II 30 (28–32), Sge III 34 (32–37), Sti III 25 (23–27), Sge IV 50 (49–51), Sti IV 48 (46–51), St IV 65 (63–68), all pointed, except for Sge IV, Sti IV, St IV, knob-tipped. Chaetotaxy: genu II: 1- 2/1, 2/0-1; genu III: 1-2/0, 2/1-1.
Male. Unknown.
Etymology. The name robustisetus is a compound of robustus (Latin for stout) and setus (Latin for seta), referring to the stout s4.
Remarks. Typhlodromips robustisetus n. sp. is similar to Typhlodromips sabaculus Denmark & Muma, 1973, but the latter has shorter Z4, s4, Sti IV and St IV (48, 35, 20 and 46 respectively), and its s4 is not as stout as in this new species.
