Type material

Male holotype, four female paratypes from the Plain Antvireo, Dysithamnus mentalis (Temminck, 1823) ( Passeriformes , Thamnophilidae ), Guajuvira Farm, Fênix, Paraná State, Brazil (23 ° 539S, 51 ° 579W), 26 July 2006, coll. A. Bispo. Holotype and paratypes are deposited at DZSJRP.

Description

Male holotype ( Figures 24–26 View Figures 24–26 ). Length of idiosoma 275, width 154. Prodorsal shield: 84 in length and 103 in width, without lacunae or pale sclerotized areas; posterior margin of prodorsal shield straight. Scapular setae se 109 in length and separated by 69; si separated by 50. Setae c1 set on hysteronotal shield; setae c2 and cp on humeral shield; setae c3 lanceolate, 16 in length and 4 in width. Distance between prodorsal and hysteronotal shields 29. Hysteronotal shield: 163 in length and 95 in width, anterior margin almost straight, surface without lacunae or pale sclerotized areas. Opisthosomal lobes short, as a pair of slightly convex extensions between setae h3; supranal concavity well expressed, long. Terminal lamellae semicircular, 11 in length with radial striation. Setae h3 separated by 57. Length of setae: h3 90, h2 158, ps2 19, ps3 8. Distance between dorsal setae: si–c1 57, c1–c2 49, c1–d1 37, d1–e1 63; e1–h1 31; h1–f2 11.

Epimerites I free with slightly divergent posterior tips; epimerites II and III without surface fields; rudimentary sclerites rEpIIa absent. Trochanters III partly flanked by sclerotized band extending from bases of epimerites IIIa. Aedeagus extending to level of setae g, 23 in length; genital arch 30 in width and 14 in length. Acetabular plates absent, genital acetabula situated on soft tegument. Distance between ventral setae: 3a–4a 22, 4a–g 38, g–ps3 20, ps3–ps3 16. Adanal shields L-shaped, broad; their anterior ends acute, inner angles touching each other anterior to anal opening, setae ps3 on adanal shields ( Figure 25 View Figures 24–26 ). Anal suckers 15 in diameter, distance between discs 22.

Tarsus IV, 24 in length, without paraxial extension, modified seta d on middle portion of the segment ( Figure 26 View Figures 24–26 ).

Female ( Figures 27–29 View Figures 27–29 ) (measurements of four paratypes). Length of idiosoma 374–385, width 176–182. Prodorsal shield: posterior margin with two shallow concavities and other features as in male, 101–106 in length and 131–139 in width. Setae se 131–139 in length and separated by 90–97; setae si separated by 69–73. Setae c1 on anterior hysteronotal shield; setae c2 and cp set on humeral shields; setae c3 lanceolate, 22 in length and 5 in width. Distance between prodorsal and hysteronotal shields 19–24. Anterior hysteronotal shield: 182–188 in length and 120–125 in width; anterior margin slightly concave, posterior margin with short and blunt median extension, surface with small lacunae mainly in median area between setae d1 and e1, and one pair of ovate pale sclerotized areas present in postero-lateral angles ( Figure 27 View Figures 27–29 ). Lobar region: 82–95 in length and 114–120 in width, lateral margins convex. Terminal cleft as a narrow inverted U, 57–60 in length and 19–27 in width. Supranal concavity absent. Setae h2 narrowly lanceolate with terminal filament, 90–114 in length, 5 in width; and setae h3 60–68 in length and separated by 46–57. Setae h1 inserted on striated tegument between the anterior hysteronotal and lobar shields. Setae h1 and f 2 in low trapezoidal arrangement. Distance between dorsal setae: si–c1 63–68, c1–c2 60–65, c1–d1 48–57, d1–e1 75–83, e1–h1 54–63, h1–f2 41–42, f2–h2 16–19.

Epimerites I free, posterior ends parallel. Bases of trochanters III almost completely flanked by sclerotized band extending from epimerites IIIa. Epimerites IVa with large posterior extension. Epigynium semicircular, 44–48 in length, 68–73 in width; tips almost extending to level of setae g. Setae ps2 and ps3 setiform, setae ps2 at mid-level of anal opening. Distance between ventral setae: 1a–3a 54–58, 3a–g 22–27, 4a–ps3 76–82, g–4a 54–68, ps2–ps3 14–16, ps2–ps2 48–52, ps3–ps3 23–26. Copulatory opening terminal. Spermatheca and spermaducts as in Figure 29 View Figures 27–29 . Legs I and II as in the male; legs III and IV subequal, ambulacral disc of legs IV extending to the level of setae h2 ( Figure 28 View Figures 27–29 ).
