Type material. Holotype female (DZSJRP n. 8935) ex Alchornea glandulosa Poepp. and Endl (Euphorbiaceae), BRAZIL: São Paulo State, Paulo de Faria, Estação Ecológica de Paulo de Faria, 19°55´S; 49°31´W, June 2003, coll. R. Buosi. Paratypes with same data as holotype (DZSJRP n. 8936–8938 and 8940– 8941): 1 female, June 2003; 4 females, 2 deutonymphs, and 1 protonymph, February 2004; 1 female, 1 protonymph, and 2 larvae, November 2003; 3 females and 1 larva, November 2003; 2 females, 1 protonymph, and 1 larva, June 2003; and (NMNH n. 2065657-8939): 1 female and 1 larva, April 2004.
Etymology. The specific name tapiae refers to the indigenous name (Tupi-Guarani) Tapiá, used to designate trees of the genus Alchornea, most common host plants of this new species, A. glandulosa.
Differential diagnosis. This species is placed in the caudatus group, annonae subgroup; it is morphologically similar to T. heteropyxis Meyer, 1993, differing by the presence of 1 solenidion on the 3rd palpal segment and sci setae longer than sce setae (2 solenidion on the 3rd palpal segment and sci setae shorter than sce setae in T. heteropyxis). T. tapiae sp. nov. is also similar to T. smithi Meyer, 1979, but it differs further by number of solenidion on the the 3rd palpal segment and length of the sci and sce setae, and also by the presence of 2 pairs of IC4 setae (1 pair of IC4 setae in T. smithi).

Gnathosoma (Fig. 15). Palp 3-segmented, 2nd segment elongate and with long filiform dorso-distal seta; 3rd segment short bearing a solenidion (5 long). Legs (Figs. 16– 19). Setation (from coxa to tarsus): I 3-1 -4-2-5-8(1), II 2-1 -4-2-5-8(1), III 1-2 -2-0-3-5, IV 1-1 -1-0-3-5; 1a setae the coxa I elongate and extend beyond the base of IC3 setae (Fig. 14); Femur I with 2 dorso-lateral squamous setae and 2 pubescent ventral setae; Femur II with 3 dorso-lateral squamous setae and 1 pubescent ventral seta.
Remark on female morphology. Underneath of the genitoventral shield there is a complex of integument folds (Fig. 3).
MALE: Unknown.
Type material. Holotype female (DZSJRP n. 8942) ex Celtis iguanae (Jacq.) Sarg. (Ulmaceae), BRAZIL: São Paulo State, São José do Rio Preto, 20°46’S; 49°15’W, April 2003, coll. P.R. Demite. Paratypes: same data as holotype (DZSJRP ns. 8943–8945) 6 females; and (NMNH n. 2065657-8946): 2 females.
Etymology. the specific name, apichai, indigenous name (Tupi-Guarani) of wrinkly, refers to the aspect of the dorsal integument.
Differential diagnosis. This species is placed in the caudatus group, anoplus subgroup, and is morphologically similar to T. burserae De Leon, 1957, and T. melhaniae Meyer, 1979, but differs from both by the length and shape of the dorsal squamous setae (dorsal setae are smooth in T. burserae, and setiform in T. melhaniae), by the pattern of dorsal ornamentation, which is highly wrinkled in T. apichai sp. nov. and more linear in T. burserae, and by the pattern on the genital plate, which is more linear in T. apichai sp. nov. and reticulated in T. melhaniae.
Tenuipalpu s nambii Castro and Feres sp. nov. (Figs. 20–27)
Description. FEMALE: (holotype, Figs. 20–27). Body length 210 (215–230 in 6 paratypes); width 125 (120–130). Dorsum (Figs. 20–21). With 2 small projections on dorso- sub lateral region of the prosoma; hysterosomal pores C shaped; prodorsal setae ve 9 (9–11), sci 12 (12–13) and sce 16 (17–19) smooth and similar hysterosomal setae, except h2 whiplike; c1 9 (10–12), c3 7 (6–10), d1 6 (6–8), d3 7 (6–8), e1 7 (6–7), e3 7 (6–9), f2 9 (9–13), f3 9 (10–13), h1 9 (9–14), h2 195 (135–150).

MALE: Unknown.
Type material. Holotype female (DZSJRP n. 8947) ex Sterculia striata St. Hil. and Naud. (Malvaceae), BRAZIL: São Paulo State, São João de Iracema, 20°28´S; 50°17´W, March 2008, coll. P.R. Demite.

Etymology. The specific name, nambii, is a compound of the indigenous words (Tupi-Guarani) nambi = ear + i = small, referring to the presence of 2 small ear-shaped projections on dorso-sub lateral region of prosoma.
Differential diagnosis. This species is placed in the caudatus group and anoplus subgroup; it is morphologically similar to T. lawrencei Baker & Pritchard, 1960, and T. mopaneae Meyer,1979, but differs from both by having palp 2-segmented and 1 solenidion on 2nd segment (palp 3-segmented and 3rd segment with 2 solenidion of unequal length in T. lawrencei and T. mopaneae), and by smooth dorsal setae (sce, c3, d3, h3, e3 and f2 setae elliptic-lanceolate and squamous in T. lawrencei and T. mopaneae).
