Typhlodromips pallinii Gonçalves, Silva & Ferla n. sp.

( Figs 2–6 )

Diagnosis. The genus Typhlodromips has the following distinctive character states: Dorsal shield usually reticulate (lateral setae j3, z2, z4, s4, Z1, S2, S4, S5 of unequal lengths, and seta s4 at least 2x length of at least one of setae z2, z4, S2, S4, S5); usually with scale-like markings on the anterolateral margin of the dorsal shield; seta R1 never inserted on dorsal shield of female; posterior margin of sternal shield straight or concave, never with posterior projection; seta Z4 variable in length but never minute (i.e., always> 15 µm).

Typhlodromips pallinii belongs to the bladderae Chant & McMurtry (2005b) subgroup, characterised by a spermatheca with the major duct swollen, bladder-like. Typhlodromips pallinii differs of T. corycus ( Denmark & Evans, 1999) by having the ratio of setae Z5: Z4 (3.0: 1.0 ratio), setae Z4 and Z5 serrated, setae j3, s4, S4, S5, Sge IV, Sti IV and St IV higher; calyx of spermatheca more elongated.

Adult Female. Five specimens examined. Idiosomal setal pattern (Chant and Yoshida-Shaul, 1992): 10A: 10B/ JV-3: ZV.

Dorsum ( Fig. 2 ). Dorsal shield reticulated, with four pairs of lyrifissures, with 337 (320–355) long, 213 (210– 215) wide at level of s4; j1 21 (18–23), j3 34 (30–37), j4 8, j5 8, j6 9 (8–10), J2 10, J5 7 (5–8), z2 14 (13–15), z4 15 (13–18), z5 8, Z1 12 (10–13), Z4 43 (40–45), Z5 100 (95–105), s4 33 (30–35), S2 19 (18–20), S4 18 (15–20), S5 17 (15–18). Setae r3 13 (10–15), R1 14 (13–15) on interscutal membrane. Setae Z4 and Z5 serrated.

Venter ( Fig. 3 ). Sternal shield a few reticulated, with three pairs of setae and two pairs of lyrifissures, setae St4 on platelets. Distances between St1–St3 66 (63–68), St2–St2 69 (68–70). Genital shield smooth, distance between St5–St5 67 (63–70) and two pairs of metapodal plates. Ventrianal shield pentagonal, smooth with 114 (110–118) long, 93 (88–100) wide at level of ZV2 and 77 (70–83) wide at level of anus.

Chelicera ( Fig. 4 ). Fixed digit with pilus dentilis, seven teeth and 33 (30–35) long, movable digit with three teeth 29 (25–33) long.

Legs ( Fig. 5 ). Sge I 27 (25–30); Sge II 25; Sge III 29 (28–30) and Sti III 22 (20–23); Sge IV 41 (38–45), Sti IV 39 (38–40) and St IV 52 (50–53).

Spermatheca ( Fig. 6 ). Major duct swollen, bladder-like.Calyx 16 (15–18) long.

Male. Unknown.
