Tenuipalpus moraesi Feres & Hernandes  n. sp. ( Figs. 9–20View FIGURES 9 – 11View FIGURES 12 – 15View FIGURES 16 – 18View FIGURES 19 – 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 3 rd palpal segment.

Female: (5 individuals) ( Figs. 9–15View FIGURES 9 – 11View FIGURES 12 – 15)—Body length 319 (286–330); width 187 (170–198). Reddish colour when alive.

Dorsum ( Fig. 9View FIGURES 9 – 11): prodorsal setae ve 4 (4–6), sci 5 (4–6) and sce 8 reduced; hysterosomal setae similar to prodorsals, except h 2 whiplike; c 1 7 (6–7), c 3 6 (6–7), d 1 6 (5–6), d 3 4 (4–5), e 1 5 (4–6), e 3 6 (5–6), f 1 6, f 2 7 (6–8), h 1 6 (6–8), h 2 125 (117–131).

Venter ( Fig. 10View FIGURES 9 – 11): ventral integument striated; IC 3 setae relatively short; IC 4 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. 11View FIGURES 9 – 11): rostrum extending to half the length of femur I; palp 3 ­ segmented, 2 nd segment elongate with a long hairy dorso­distal seta; 3 rd 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 3 ­ 1 ­4­ 2­5 ­ 8 (1), II 2 ­ 1 ­4­ 2­5 ­ 8 (1), III 1­2 ­ 2 ­ 0­3 ­ 4, IV 1 ­ 1 ­ 1 ­ 0­2 ­ 4. 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. 16–18View FIGURES 16 – 18)(1 individual)—Body length 214; width 145. Reddish colour when alive.

Dorsum ( Fig. 16View FIGURES 16 – 18): 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, c 1 6, c 3 4, d 1 6, d 3 4, e 1 4, e 3 4, f 1 6, f 2 6, h 1 7, h 2 139.

Venter ( Figs. 17–18View FIGURES 16 – 18): ventral tegument striated; IC 3 setae relatively short; IC 4 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 (c 1, c 3, d 1, d 3, e 1, e 3, f 1, f 2, h 1 and h 2). 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. 19View FIGURES 19 – 20)—Body length 231–234; width 144–155.

Dorsal setae: sce serrate. ve 2–3, sci 2–3, sce 28–32, c 1 2–3, c 3 9–11, d 1, d 3 and e 1 2 –3, e 3 8 –11, f 1 9–13 and f 2 9–12, h 2 80, h 1 9–10.

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

Larva: (2 individuals) ( Fig. 20View FIGURES 19 – 20)—Body length 166–177; width 125–128.

Dorsal setae: sce serrate, 12; h 2 whiplike 44; other dorsal setae reduced and lanceolate, 2 m.

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

Relation to host: inhabits the upper surface of leaves.
