Griseb.; Piracicaba, August 2002, 10 females on Carica papaya L. and 7 females on Esenbeckia leiocarpa Engl.

Previous records. Brazil [States of Bahia, Ceará, Maranhão, Minas gerais, Paraíba, Pernambuco, Rio Grande do Sul, São Paulo and Sergipe (Moraes et al., 2004b); Alagoas, Pará, Paraíba, Piauí and Rio Grande do Norte (Lawson-Balagbo et al., 2008) and Roraima (Gondim Jr. et al., 2012)]; Colombia, Guyana, Martinique, Peru and Venezuela (Moraes et al., 2004b).

Measurements of females (n= 7).

Dorsal shield 319 (310–330) long and 222 (215–230) wide. Setae j1 29 (22–35), j3 25 (17–28), j4 15 (12–17), j5 13 (12–17), j6 17 (15–19), J2 19 (15–21), J5 8 (6–9), z2 20 (15–23), z4 22 (15–25), z5 16 (13–17), Z1 19 (15– 21), Z4 21 (16–24), Z5 66 (56–70), s4 29 (19–35), S2 23 (17–26), S4 26 (20–30), S5 26 (20–30), r3 16 (13–19), R1 15 (12–16). Distances between St1 - St3 52 (52–59), St2 - St2 72 (65–77), St5 - St5 76 (73–78). Ventrianal shield 93 (87–98) long, 53 (50–57) wide at level of ZV2 and 63 (59–70) wide at anus level. Movable cheliceral digit 24 (23– 24) long, with one tooth; fixed cheliceral digit 21 (20–22) long, with 4–5 teeth. Calyx of spermatheca 19 (18–20) long. Leg macrosetae: Sge I 23 (18–25), Sge II 24 (19–27), Sge III 29 (26–34), Sti III 24 (21–26), Sge IV 43 (35– 47), Sti IV 29 (24–33), St IV 55 (42–63), all pointed, except for Sge IV, Sti IV and St IV, knob-tipped.

Remarks. The measurements of the specimens collected fit the original description, except for the shorter spermathecal calyx (25 in the original description). The shorter calyx was also mentioned by Moraes & Mesa (1988) for specimens from Colombia and by Gondim Jr. & Moraes (2001) for specimens of the Brazilian Sates of Pernambuco and São Paulo (18 and 16 respectively). Specimens collected in this study in Pariquera-Açu have shorter j3, s4, S2, Z5, Sge II, Sge IV and St IV than specimens from the other two localities (Itu and Piracicaba), wich have j3 longer than mentioned in the original description (21), as also reported by Moraes & Mesa (1988) (25–31) for specimen from Colombia. Similarly to what was observed for specimens collected in this study, Sge I and Sge II have been consistently mentioned as pointed in the literature (including the original description), whereas macrosetae of leg IV have been consistently mentioned as knob-tipped. However, some differences have been reported in relation to Sge III: while mentioned as knob-tipped in the original description, Moraes & McMurtry (1983) mentioned it as pointed for some and bulbous for other populations from northeast Brazil, whereas Moraes & Mesa (1988) reported it as pointed for Colombian populations.
