Tenuipalpus ariauae  n. sp. Feres & Hernandes ( Figs. 21–30View FIGURES 21 – 23View FIGURES 24 – 27View FIGURES 28 – 30)

Diagnosis: This species is placed in the caudatus group, anoplus subgroup ( Baker & Tuttle 1987; Meyer 1993), and is similar to T. protectus Meyer (1979)  by the pattern of dorsal ornamentation. In T. ariauae  , however, only setae sci is developed, the other dorsal setae are minute, except for setae h 1, which are very long and whiplike; also differ in the chaetotaxy of legs: T. ariauae  : femur IV 1, genu I and II 3, tibia IV 3, tarsi 7 (1)­ 7 (1)­ 3 ­ 3; T. protectus  : femur IV 2, genua I and II 2, tibia IV 2, tarsi 8 (1)­ 8 (1)­ 5 ­ 5. In T. ariauae  the short solenidion on 3 rd palpal is absent, whereas in T. protectus  that solenidion is about half the length of the long solenidion on that segment.

Female: (7 individuals)—Body length 264 (253–275), width 143 (143–154). Reddish colour when alive.

Dorsum ( Fig. 21View FIGURES 21 – 23): ve 4 (3–6), sci 21 (20–22), spatulate­serrate, sce 10 (8–12), lanceolate; hysterosomal setae similar to ve and sce; except h 2 whiplike; c 1 6 (4–7), c 3 4 (3–6), d 1 4 (4–6), d 3 4 (4–6), e 1 4 (4–6), e 3 3 (3–4), f 1 4 (3–5), f 2 4 (3–6), h 1 4 (3–6), h 2 122 (120–131).

Venter ( Fig. 22View FIGURES 21 – 23): ventral integument striated; IC 3 setae short; IC 4 setae long, exceeding the bases of pre­genital setae; genital setae similar to anal setae, shorter than pre­genital setae.

Gnathosoma  ( Fig. 23View FIGURES 21 – 23): rostrum extending to 2 / 3 of the length of femur I; palp 3 ­ segmented, 2 nd segment elongate with a long hairy seta dorso­distally; 3 rd segment short (2 m) and bearing a long solenidion (8 m), 4 times the length of segment; rostral shield split 2 / 3 of its length.

Legs ( Figs. 24–27View FIGURES 24 – 27): chaetotaxy (from coxa to tarsus): I 3 (including 1 a)­ 1­4 ­ 3­5 ­ 7 (1), II 2 ­ 1 ­4­ 3­5 ­ 7 (1), III 1­2 ­ 2 ­ 0­3 ­ 3, IV 1 ­ 1 ­ 1 ­ 0­3 ­ 3. Femur I with 2 serrate dorso­lateral setae and 2 hairy ventral setae; femur II with 3 serrate dorso­lateral setae and 1 hairy ventral seta.

Male: Unknown.

Immatures: larvae, protonymphs and deutonymphs have the full complement of dorsal setae of the adult, viz. 3 prodorsal pairs (ve, sci and sce) and 10 hysterosomal pairs (c 1, c 3, d 1, d 3, e 1, e 3, f 1, f 2, h 1 and h 2). Central region of idiosoma covered by transverse rows of integument folds.

Deutonymph: (2 individuals) ( Fig. 28View FIGURES 28 – 30)—Body length 250 (245–256); width 137 (136–139).

Legs: chaetotaxy (from coxa to tarsus): I 3 ­ 1 ­4­ 3­5 ­ 7 (1), II 2 ­ 1 ­4­ 3­5 ­ 7 (1), III 1­2 ­ 2 ­ 0­ 3 ­ 3, IV 1 ­ 0­1 ­ 0­3 ­ 3.

Protonymph: (2 individuals) ( Fig. 29View FIGURES 28 – 30)—Body length 192 (190–193); width 117 (111–122).

Legs: chaetotaxy (from coxa to tarsus): I 1 ­ 0­3 ­ 1­5 ­ 5 (1), II 1 ­ 0­2 ­ 1­5 ­ 5 (1), III 0­ 0­2 ­ 0­ 3 ­ 3.

Relation to host: inhabits the upper surface of leaves.

Type material: Female holotype, from Qualea grandiflora Mart.  ( Vochysiaceae  ), April 26, 1990, “Sítio” São Luiz (20 º 50 ’S, 49 º 18 ’W), São José do Rio Preto, São Paulo, Brazil, (DZSJRP n. 6292).

Paratypes— 3 females, 2 deutonymphs, 2 protonymphs and 1 larva, June 21,1990 and 2 females, July 23, 1990, “Sítio” Santo Antonio (20 º 44 ’S; 49 º 21 ’W); 1 female, July 23, 1990, “Sítio” São Luiz (20 º 50 ’S, 49 º 18 ’W), São José do Rio Preto, São Paulo, Brazil (DZSJRP ns. 6292–6300); same host as holotype.

Etymology: ariauae  , from ariauá, referring to the indigenous name of the host plant.
