description: Tenuipalpus moraesi Feres & Hernandes n. sp. (Figs. 9–20)
Diagnosis: This species is placed in the caudatus group, anoplus subgroup (Baker & Tuttle 1987; Meyer 1993) and is similar to T. emeticae Meyer (1979), but differs by the wrinkled pattern of dorsal ornamentation, the chaetotaxy of trochanter III (2 tactile setae instead of 1 as in T. emeticae) and by the presence of only one solenidion on the 3rd palpal segment.
Female: (5 individuals) (Figs. 9–15)—Body length 319 (286–330); width 187 (170–198). Reddish colour when alive.
Dorsum (Fig.9): prodorsal setae ve 4 (4–6), sci 5 (4–6) and sce 8 reduced; hysterosomal setae similar to prodorsals, except h2 whiplike; c1 7 (6–7), c3 6 (6–7), d1 6 (5–6), d3 4 (4–5), e1 5 (4–6), e3 6 (5–6), f1 6, f2 7 (6–8), h1 6 (6–8), h2 125 (117–131).
Venter (Fig.10): ventral integument striated; IC3 setae relatively short; IC4 setae long, exceeding the bases of pre­genital setae; genital setae short and similar to anal setae; genital and anal shields slightly separated from each other.
Gnathosoma (Fig.11): rostrum extending to half the length of femur I; palp 3­ segmented, 2nd segment elongate with a long hairy dorso­distal seta; 3rd segment short (2 m) bearing a long solenidium (7 m), 3.5 times the length of the segment; rostral shield split 2/3 its length.
Legs (12–15): Chaetotaxy (from coxa to tarsus): I 3­1 ­4­2­5­8(1), II 2­1 ­4­2­5­8(1), III 1­2 ­2­0­3­4, IV 1­1 ­1­0­2­4. Femur I with two serrate dorso­lateral setae and two pubescent ventral setae; femur II with 3 serrate dorso­lateral setae and 1 pubescent ventral seta.
Male: (Figs. 16–18)(1 individual)—Body length 214; width 145. Reddish colour when alive.
Dorsum (Fig.16): central region of prodorsum with two longitudinal rows of mountain range­like ornamentation; dorsal setae as described for the female: ve 4, sci 4, sce 7, c1 6, c3 4, d1 6, d3 4, e1 4, e3 4, f1 6, f2 6, h1 7, h2 139.
Venter (Figs.17–18): ventral tegument striated; IC3 setae relatively short; IC4 setae long, exceeding the bases of pre­genital setae; genital setae short and similar to anal setae. Gnathosoma: similar to that of the female.
Legs: same chaetotaxy as that of female.
Immatures: larvae and protonymphs have the full complement of dorsal setae of the adult, viz. 3 prodorsal pairs (ve, sci and sce) and 10 hysterosomal pairs (c1, c3, d1, d3, e1, e3, f1, f2, h1 and h2). Propodosomal seta sce relatively large and serrate. Central region of idiosoma covered by transverse rows of integument folds. Deutonymphs were not found.
Protonymph: (2 individuals) (Fig. 19)—Body length 231–234; width 144–155.
Dorsal setae: sce serrate. ve 2–3, sci 2–3, sce 28–32, c1 2–3, c 3 9–11, d1, d3 and e1 2 –3, e 3 8 –11, f 1 9–13 and f 2 9–12, h2 80, h 1 9–10.
Legs: chaetotaxy (from coxa to tarsus): I 3 ­0­3­1­5­5(1), II 1 ­0­3­1­5­5(1), III 1­1 ­2­0­ 3­3, IV 0­0­1­0­3­3.
Larva: (2 individuals) (Fig. 20)—Body length 166–177; width 125–128.
Dorsal setae: sce serrate, 12; h2 whiplike 44; other dorsal setae reduced and lanceolate, 2 m.
Legs: chaetotaxy (from coxa to tarsus): I 2 ­0­3­1­5­5(1), II 0­0­3­1­5­5(1), III 0­0­2­0­ 3­3.
Relation to host: inhabits the upper surface of leaves.
Type material: Holotype female, ex. Sebastiania brasiliensis Spreng (Euphorbiaceae), April 8, 2004, Estação Ecológica de Paulo de Faria (19º55’– 19º58’S /49º31’– 49º32’W), Paulo de Faria, São Paulo State, Brazil (DZSJRP n.6285). Paratypes — 2 females and 1 male from the host and locality types, 2 females from unidentified Euphorbiaceae, June 21,1990, “Sítio” São Luiz (20º50’S, 49º18’W), São José do Rio Preto, São Paulo, Brazil (DZSJRP n.6286–6291).
Etymology: moraesi, in homage to Dr. Gilberto José de Moraes, eminent acarologist of the Escola Superior de Agricultura “Luiz de Queiroz” (ESALQ), Universidade de São Paulo (USP), Piracicaba, SP, Brazil.
