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 c 1 105 (88–110); prodorsal shield normally covering gnathosoma, with irregular ornamentation. Stigma associated to anterior notch of prodorsal shield. Pits v 2 not recognizable. Tergites C and D ornamented with irregular reticules. Lengths of setae: v 1 30 (29–32), sc 1 13 (11–14), sc 2 40 (38–40), c 1 37 (33–37), c 2 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 sc 2; v 1, c 2 and h, setiform; sc 2, c 1, d, e and f leaf shaped, tricarinate; d, e and f wider medially; sc 1 capitate. Distances between dorsal setae: v 1 –v 1 30 (28-30), sc 2 –sc 2 43 (42–43), sc 1 –sc 1 37 (31–38), sc 1 –sc 2 8 (5–8) v 1 –sc 2 18 (15–18), c 1 –c 1 46 (46–49), c 2 –c 2 58 (57–60), c 1 –c 2 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 sc 1 inserted posteriorly to sc 2.

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; 3 b 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 3 a. Apodeme 4 extending diagonally from bases of setae 3 b 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.

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, 10 º 18 ’ 31,46 ’’S, 36 º 38 ’ 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 c 2 setiform and barbed, whereas in D. serissae   this seta is laminate tricarinate. In addition, in D. serissae   ventral seta 1 a is adjacent to apodeme 1 (vs. distant from apodeme 1 in D. annonae   ).
