Iphiseiodes matatlanticae n. sp.

( Figures 1–5 )

Adult female (10 specimens measured).

Dorsum. Dorsal shield smooth, 366 (325–387) long and 264 (240–290) wide at level of s4, surrounded by darkened, less sclerotised cuticle that extends to ventrolateral region of idiosoma, where it becomes membranous; seven pairs of pores and 13 pairs of lyrifissures visible. Setae j1 19 (16–25), j3 11 (8–13), j4 3, j5 3, J2 3, J5 3 (4– 5), z2 3, z4 3, z5 3, Z1 3, Z4 3 (3–4), Z5 16 (14–18), s4 101 (90–110), S2 3, S4 3 and S5 4 (3–6), r3 4 (4–5), R1 3. Setae r3 and R1 inserted laterad dorsal shield in soft cuticle. All setae smooth.

Venter. Sternal shield much wider than long and mostly smooth, with few lateral striae; with three pairs of setae and two pairs of lyrifissures. Distances between st1–st3 52 (49–56), st2-st2 77 (71–82). Genital shield smooth; distance between st5-st5 109 (100–113). Ventrianal shield pentagonal and strongly reticulated, 107 (100–115) long, 119 (115–125) wide at level of ZV2 and 110 (105–115) wide at median level of anus, with three pairs of pre-anal setae (JV1, JV2, ZV2) and a pair of pores medad JV2. With two pairs of metapodal shields; five pairs lyrifissures in surrounding soft cuticle. Peritreme extending to anterior of j3.

Chelicera. Fixed digit 35 (32–37) long, with 13 teeth; movable digit 35 (32–36) long with 3 teeth.

Spermatheca. Calyx funnel-shaped 5 (6–7) long; atrium indistinct.

Legs. Macrosetae present on all legs: Sge I 48 (44–52), Sge II 28 (24–33), Sge III 42 (38–45), Sti III 28 (25– 31), Sge IV 70 (60–80), Sti IV 47 (43–50) and St IV 40 (37–45) ( Fig. 5 ); Sge IV and Sti IV blunt to spatulate; other macrosetae setiform; Sge III, Sge IV, Sti IV and St IV distally hyaline. Chaetotaxy of genu II 2, 2/0, 2/0,1; genu III 1, 2/1, 2/0, 1.

Male unknown.

Material examined. Holotype female, on Coffea arabica cv. Mundo Novo ( Rubiaceae ), Monte Alegre do Sul, State of São Paulo, Brazil (22° 40’ 73” S, 46° 38’ 99” W), collected by J.L.C. Mineiro, 1.iv.2004 (Deposited at LA- CEIB). Paratypes, eight females, same data as holotype except 23.xii.2004, 13.iv.2005, 8.v.2006, 20.vi.2006 and 4.viii.2006 (deposited at LA-CEIB); one female, 01.viii.2002, on Trichilia pallida Swartz (Meliaceae) , Itu, State of São Paulo, Brazil (23° 12’ 86” S; 47° 10’ 70” W), collected by N.C. Mesa (Deposited at ESALQ-USP).

Etymology. The name matatlanticae refers to “ Mata Atlântica”, the Portuguese name for the Brazilian biome that includes the type locality, a currently highly disturbed habitat.

Remarks. The original description of I. nobilis refers to the dorsal shield of this species as smooth. However, a re-examination of the holotype by Aponte & McMurtry (1995) showed it to be reticulated. This species is most similar to I. neonobilis and I. nobilis ; however these two species have reticulated dorsal and genital shields. In addition, I. neonobilis has subtriangular ventrianal shield and I. nobilis has very long and setiform macrosetae on genu and tibia of legIV, differing from this new species.
