( Figs. 1–6 View FIGURE 1 View FIGURE 2 View FIGURE 3 – 6 )
Diagnosis. Female: Setae c2 setiform and barbed; ornamentation as in Fig. 1 View FIGURE 1 ; tegula rounded; seta 1a distant from apodeme 1; setae d, e and f leaf shaped.
Description. ADULT FEMALE (holotype). Gnathosoma: subcircular in dorsal view and subtriangular in ventral view, length 29 (29–31 in 5 paratypes), maximum width 20 (20–25); dorsal apodeme indistinct. Seta ch (11–15) and vm (10) smooth; seta pp not seen. Palpus short, with 1 small terminal seta and 2 cone-shaped structures. Pharynx fusiform, 12 (11–13) long and 5 (5–7) maximum wide.
Idiosoma ( Figs. 1 View FIGURE 1 and 2 View FIGURE 2 ): length 150 (150–165), width at level of c1 105 (88–110); prodorsal shield normally covering gnathosoma, with irregular ornamentation. Stigma associated to anterior notch of prodorsal shield. Pits v2 not recognizable. Tergites C and D ornamented with irregular reticules. Lengths of setae: v1 30 (29–32), sc1 13 (11–14), sc2 40 (38–40), c1 37 (33–37), c2 25 (24–26), d 24 (22–25), e 22 (21–22), f 24 (22–26) and h 16 (12–16). All dorsal setae barbed, except sc2; v1, c2 and h, setiform; sc2, c1, d, e and f leaf shaped, tricarinate; d, e and f wider medially; sc1 capitate. Distances between dorsal setae: v1–v1 30 (28-30), sc2–sc2 43 (42–43), sc1–sc1 37 (31–38), sc1–sc2 8 (5–8) v1 –sc2 18 (15–18), c1–c1 46 (46–49), c2–c2 58 (57–60), c1–c2 30 (25–30), d–d 20 (19–21), f–f 12 (12–13), e–f 11 (11–13) and h–h 20 (18–20). Seta sc1 inserted posteriorly to sc2.
Coxisternal setae 1a 6 (5–7), near middle of apodeme 1; 2a 10 (9–11), near middle of coxisternal plate I; 3a 15 (12–15), near anterior end of apodeme 3; 3b 8 (7–8), on posterior end of apodeme 4. Apodeme 1 conspicuous, fused to anterior end of prosternal apodeme. Prosternal apodeme interrupted medially, and not fused with sejugal apodeme. Apodeme 2 short, not fused to prosternal apodeme. Sejugal apodeme uninterrupted. Apodeme 3 short with constriction near anterior end, extending diagonally from anterior end of trochanter III to proximity of setal bases 3a. Apodeme 4 extending diagonally from bases of setae 3b to middle of poststernal apodeme, both apodemes slightly fused to each other by proximal tips of apodemes 4. Poststernal apodeme bifurcated anteriorly. Coxisternal plates smooth. Tegula (13–15) long and (5–6) wide; posterior margin rounded. Seta ps smooth.
Legs ( Figs. 3–6 View FIGURE 3 – 6 ): length (femur to tarsus): leg I 45 (41–48), leg II 38 (38–42), leg III 70 (69–74), leg IV 47 (44–47). Number of setae (solenidia in parentheses) on femur, genu and tibiotarsus, respectively: leg I: 3–4–6(1 φ)+7(1 ω), leg II: 3–3–4–4(1 ω), leg III: 1+3–4–4. Tarsal solenidion ω of tibiotarsus I 5 (4–5) long, stout, wider medially. Sensory cluster of tibia I incomplete (φ 1 lacking), solenidion φ 2 3 (3), robust, slightly capitate; eupathidiun k (5); both inserted at approximately the same level. Seta d of tibia I 21 (16–22) long, serrate. Solenidion ω of tarsus II proximal, 4 (4–5) long, stout, wider medially; seta pl´´absent. Seta d of tibia II 10 (9–11) long, smooth. Femurogenu IV 18 (17–18) long; tibiotarsus IV 8 (8–9) long. Lengths of leg IV setae: v´F 6 (6–8), v´G 10 (10–11), v'Ti 15 (15–16) and tc” 20 (17–20); Setae v'G, v'F and v'Ti smooth; Seta v'Ti broad sword-shaped and tc" serrate.

Type deposition. Whole type series at UNESP / SJRP.
Additional material. 5 females (collection number 120 DJMS) from Annona muricata , BRAZIL: State of Sergipe, Neópolis, 10º18’31,46’’S, 36º38’57,19’’W, 21 July 2005, coll. J.M. Sousa ( UFRPE).
Etymology. The species name refers to the plant on which it was found.
Differential diagnosis. The female of Daidalotarsonemus annonae is most similar to Daidalotarsonemus serissae Yang, Ding and Zhou, 1987 . Both species have a very similar pattern of dorsal ornamentation on the prodorsal shield and on tergites C and D ( Fig. 1 View FIGURE 1 ), unlike that of other known species in the genus, the dorsal setae are similar in shape and size, and the tegula is rounded. D. annonae has dorsal opisthosomal seta c2 setiform and barbed, whereas in D. serissae this seta is laminate tricarinate. In addition, in D. serissae ventral seta 1a is adjacent to apodeme 1 (vs. distant from apodeme 1 in D. annonae ).
