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 R1, and with a smooth band immediately anteriad of Z4 and S4; dorsal setae subcylindric and smooth, except for j1, J5, S5 and R1, 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 R1 and with a smooth band immediately anteriad of Z4 and S4, with eight pairs of distinguishable lyrifissures and four pairs of pores, 350 long and 190–210 wide. Setae j1 33–34, j3 40–41, j 4 15–18, j 5 9–10, j 6 22–24, J2 27, J 5 9– 10, z 2 30–32, z4 32–37, z 5 20–21, Z1 34–35, Z4 55–56, Z5 75–72, s4 50 –51, S2 41 –43, S 4 30 –31, S5 12, r 3 29–30, R 1 23–24. Setae subcylindric and smooth, except for j1, J5, S5 and R1, 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 St1 - St3 67–70, St2 - St2 67–68. Genital shield smooth; distance between St5 - St5 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 (JV1, JV2 and ZV2); JV4, JV5, ZV1 and ZV3 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 j1.

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 j3, Z4 and Z5 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 z2 and a smaller number of teeth on the fixed cheliceral digit (five teeth).
