Typhlodromalus ingae  n. sp.

(Figures 31–35)

Diagnosis. Females with dorsal shield covered mainly by roundish ornamentation, with lateral reticula in the area anteriad of R 1, and with a smooth band immediately anteriad of Z 4 and S 4; dorsal setae subcylindric and smooth, except for j 1, J 5, S 5 and R 1, setiform; calyx of spermatheca tubular.

Specimens examined. Holotype female and one paratype female from Inga vera Willd., Luis Antonio  , State of São Paulo, 20 September 2001, L.V.F. Silva coll deposited at ESALQ-USP.

Description. Female (n= 2). Figures 31–35.

Dorsum. Dorsal shield covered mainly by roundish ornamentation, with lateral reticula on the area anteriad of R 1 and with a smooth band immediately anteriad of Z 4 and S 4, with eight pairs of distinguishable lyrifissures and four pairs of pores, 350 long and 190–210 wide. Setae j 1 33–34, j 3 40–41, j 4 15–18, j 5 9–10, j 6 22–24, J 2 27, J 5 9– 10, z 2 30–32, z 4 32–37, z 5 20–21, Z 1 34–35, Z 4 55–56, Z 5 75 – 72, s 4 50 –51, S 2 41 –43, S 4 30 –31, S 5 12, r 3 29–30, R 1 23–24. Setae subcylindric and smooth, except for j 1, J 5, S 5 and R 1, setiform.

Venter. Sternal shield mostly smooth, except a for few lateral lines; posterior margin indistinct; with three pairs of setae and two pairs of lyrifissures; distances between St 1 - St 3 67–70, St 2 - St 2 67–68. Genital shield smooth; distance between St 5 - St 5 82. Ventrianal shield vase-shaped, smooth, 120 long, 69–73 wide at level of ZV 2, 70 wide at anus level, with three pairs of pre-anal setae (JV 1, JV 2 and ZV 2); JV 4, JV 5, ZV 1 and ZV 3 on unsclerotised cuticle and a pair of elliptical pre-anal pores posteromesad of JV 2. Ventral setae smooth and pointed. With two pairs of metapodal plates. Peritreme extending beyond level of j 1.

Chelicera. Movable cheliceral digit 29–30 long, with four teeth; fixed cheliceral digit 33–35 long, with nine teeth and a pilus dentilis.

Spermatheca. Calyx tubular, 18–19 long; atrium elongate.

Leg macrosetae. Sge I 18–19, Sge II 19, Sge III 27, Sti III 18, Sge IV 51–52, Sti IV 27, St IV 72–74, all knobed. Chaetotaxy: genu II 2 - 2 / 1, 2 / 0-1; genu III 1-2 / 1, 2 / 0-1.

Male. Unknown.

Etymology. The name ingae  refers to Inga  , genus of the plant substrate from which the type specimens were collected.

Remarks. Typhlodromalus ingae  n. sp. is similar to T. feresi  . The latter differs from the new species by having j 3, Z 4 and Z 5 shorter (25–26, 39 – 40 and 56–57 respectively), spermathecal calyx longer (28–32) and atrium nodular. This new species is also similar to Typhlodromalus feresisimilis  n. sp. but the latter has most dorsal setae lanceolate, shorter z 2 and a smaller number of teeth on the fixed cheliceral digit (five teeth).
