( Figs. 1–6 ) Diagnosis : Females of this new species are similar to Daidalotarsonemus jamesbakeri Smiley in the shape of ornamentation of C and D tergites (longitudinal, waved continuous ridges), but differ by having the dorsal opisthosomal seta e phylliform and not setiform as in D. jamesbakeri . Adult female ( 5 specimens measured). Gnathosoma: subcircular in dorsal view and subtriangular in ventral view, length 35 (33–37), maximum width 28 (23–31); dorsal apodeme distinct. Setae ch 15 (14–16) and vm 10 (10–11) smooth; seta pp 20, filiform, almost indiscernible in dorsoventral view. Palpus moderately long, with 2 small subterminal setae and terminal cone­shaped structures. Pharynx fusiform, 19 (18–20) long and 8 (8–9) wide at widest region. Idiosoma ( Figs. 1 and 2 ): length 206 (200–215), width at level of c1 110 (100–125); prodorsal shield normally covering gnathosoma, with irregular ornamentation. Stigma near lateral notch of prodorsal shield, equidistant to bases of setae v1 and sc2 . Tergites C and D ornamented with longitudinal, waved continuous ridges. Lengths of the setae: v1 28 (25–30), sc1 14, sc2 36 (33–39), c1 24 (22–26), c2 15 (13–16), d 41 (40–42), e 29 (24–31), f 41 (40–44), h 18 (16–20). All setae serrate; v1 , sc2 , c1 , c2 and h setiform; d and f laminate tricarinate, wider medially; e phylliform; sc1 capitate and with tiny spines. Distances between dorsal setae: v1–v1 28 (25–30), sc2–sc2 50 (47–55), v1 –sc2 29 (25–32), c1–c1 47 (45–50) c2–c2 109 (105–115), c1–c2 39 (37–40), d–d 40 (37–42), f–f 16 (15–18), e–f 15 (15–16), h–h 20 (20–21). Seta sc1 inserted anteriorly to sc2 . FIGURE 1. Daidalotarsonemus folisetae sp. nov. (female). Dorsal surface. FIGURE 2. Daidalotarsonemus folisetae sp. nov. (female). Ventral surface. FIGURES 3–6. Daidalotarsonemus folisetae sp. nov. (female). 3, leg I; 3’, sensorial cluster; 4, leg II; 5, leg III; 6, leg IV. Coxisternal setae 1a 7 (6–10), near middle of apodeme I; 2a 12 (12–13), near middle of apodeme II; 3a 19(16–22), near anterior end of apodeme III; 3b 10 (10–12), on posterior end of apodeme IV. Apodeme I conspicuous, fused to anterior end of prosternal apodeme. Apodeme II short, not fused to prosternal apodeme. Prosternal apodeme conspicuous from junction with apodeme I to level of posterior end of apodeme II, but diffuse from this point to level of sejugal apodeme; conspicuous section with a median node; anterior half of diffuse section widened. Sejugal apodeme uninterrupted, with median indentation. Apodeme III with a constriction near anterior end, extending diagonally from proximity of base of seta 3a to anterior margin of trochanter III; apodeme IV extending diagonally from the middle of the poststernal apodeme to base of seta 3b . Poststernal apodeme bifurcated anteriorly. Coxistenal plates smooth. Tegula wide and short, 4 (4–5) long and 15,5 (15–16) wide; posterior margin straight. Seta ps smooth. Legs ( Figs.3–6 ): lengths (femur to tarsus): leg I 52 (50–53), leg II 48 (46–50), leg III 55 (52–59), leg IV 34 (31–36). Number of setae (solenidia in parentheses) on femur, genu, tibia and tarsus, respectively: leg I: 3­4­5(2)­7(1), leg II: 3­3­4­4(1), leg III: 1+2­4­4. Tarsal solenidion of tibiotarsus I 6 (5–7), stout, wider medially. Sensory cluster of tibia I complete, solenidion 3 (2–3), slender, capitate; solenidion 3 (3–4), robust, slightly capitate; famulus k 6 (6–7); all those inserted at approximately the same level. Seta d of tibia I 30 (27–32), serrate. Solenidion of tarsus II proximal, 5 (4–5) long, stout, wider medially; seta pl´´ absent. Seta d of tibia II 16 (15–19), serrate. Femorogenu IV 22 (20– 25); tibiotarsus IV 12 (11–13). Length of leg IV setae: v´F 12 (10–15), v´ G 21 (20–23), v´ Ti 29 (22–32) and tc´´ 60 (55–65); all setae smooth; v’G and v´Ti laminar.
