description: Daidalotarsonemus childersi Rezende, Ochoa & Lofego sp. nov.   
(Figs. 18–20)  
 Diagnosis. Female: Gnathosoma: Palpal length about 1/4 length of gnathosoma. Dorsum: Coarse ornamentation on prodorsum and tergite D. Tergite C with three transverse rows of cells, grouped between setae c1, and same number of cells per row (four), except for last (five). Setae v1, sc2, c1, c2 and h unmodified in shape. Setae v1 as long as sc2 (~ 30). Setae c1 and c2 similar in length (~ 25), both longer than h (~ 17). Setae c1 inserted near midlength of tergite C. Setae d, e and f leaf-shaped. Setae d and f identical in shape (ensiform with two lateral veins) but slightly different in length (~ 36 and ~ 31, respectively) and width (~ 8 and ~ 10, respectively). Setae e linear-lanceolate in shape, shorter than d and f, but as long as h (~ 17). Setae f ~10 distant from each other, on rounded tubercles. Venter: Tegula truncate, slightly arched. Apodemes distinct, except for prosternal apodeme from level of apodemes 2 to sejugal apodeme. Apodemes 2 not fused to prosternal apodeme. Poststernal apodeme weakly bifurcated anteriorly. Legs: sensory cluster of tibiotarsus I complete. Seta tc” of tarsus II slender and serrate. Male & larva: unknown.   
 Description (12 specimens measured):   
 Gnathosoma: subtriangular in ventral view, length 33 (31–36), maximum width 26 (24–28). Setae dgs 15 (14–15) and vgs 7 (7–8) smooth; palps length 12 (11–14), with two small subterminal setae and terminal projections. Pharynx length 18 (16–19), maximum width 7 (7–8).   
 Idiosoma—dorsum: length 206 (205–208), width at level of c1 129 (125–133). Prodorsal shield with coarse ornamentation. Tergite C reticulate between setae c1. Tergite D with longitudinal depressions between setae d. Lengths of setae: v1 29 (27–31), sc1 16 (16–17), sc2 30 (28–32), c1 26 (24–27), c2 23 (21–25), d 36 (33–37), e 18 (17–20), f 31 (29–33) and h 17 (15–19). Maximum widths of expanded setae: d 8, e 3 and f 10. All dorsal setae serrate, except for sc2, c1 and c2. Setae v1, sc2, c1, c2 and h slender; d and f ensiform; e linear-lanceolate. All inserted on tubercles, except for h. Distances between dorsal setae: v1–v1 33 (31–36), sc2–sc2 58 (56–63), v1–sc2 31 (29–34), c1–c1 53 (52–55), c2–c2 104 (101–107), c1–c2 41 (39–43), d–d 36 (35–39), f–f 9 (9–10), e–f 18 (18– 20) and h–h 22 (20–25). Setae sc1 at same level of sc2.   
 Idiosoma—venter: setae 1a 9 (8–11); 2a 11 (11–12); 3a 14 (13–16) near anteromedial margins of apodemes 3; 3b 9 (9–11) on posterior ends of apodemes 4. Apodemes 1 conspicuous, fused to anterior end of prosternal apodeme. Apodemes 2 short and not fused to prosternal apodeme. Prosternal apodeme conspicuous from junction with apodeme 1 to apodemes 2 and inconspicuous from that point to sejugal apodeme. Sejugal apodeme interrupted medially. Apodeme 3 extending diagonally from proximity of base of seta 3a to (but not laterally beyond) anterior margin of trochanter III. Apodeme 4 extending diagonally from posterior third of poststernal apodeme nearly to base of seta 3b. Poststernal apodeme bifurcated anteriorly. Tegula 14 (13–15) wide, 4 (4–5) long, posterior margin slightly arched. Setae ps 15 (14–19) smooth.   
 Legs: Lengths: leg I 49 (48–53), leg II 58 (56–60), leg III 93 (92–96). Number of setae: leg I: 3-4-6(2)+7(1), leg II: 3-3-4-4(1), leg III: 1+3-4-4. Tarsal solenidion ω of tibiotarsus I 5. Sensory cluster of tibiotarsus I complete, solenidion φ1 3, slender, capitate; solenidion φ2 4, robust, slightly capitate; famulus k 6; all inserted at approximately same level. Seta d of tibiotarsus I 33 (31–35), serrate. Solenidion ω of tarsus II length 5. Seta d of tibia II 24 (22–26), serrate. Femorogenu IV 13 (12–15); tibiotarsus IV 11 (11–12). Length of leg IV setae: v’ F 6 (6–8), v’ G 15 (14–18), v´ Ti 28 (27–30) and tc” 34 (32–36); all setae smooth, except for v’ G; v’ Ti tapered.   
 Type material: Holotype ♀ and five paratypes ♀ deposited at USNM; three paratypes ♀ at CALFAUCR; three paratypes ♀ at CNC; three paratypes ♀ at DZSJRP; one paratype ♀ at FAAS; three paratypes ♀ at FSCA; three paratypes ♀ at QM.   
 Locality: All specimens on Camellia sinensis (L.) Kuntze (Theaceae), Charleston, State of South Carolina, USA, C. C. Childers.   
 Etymology: This species is named in honor of the late Dr. Carl C. Childers (1938-2023), University of Florida, for his dedication to the study of mites associated to major tree crops around the world.
