(Figs. 7–8)
Diagnosis. This species resembles L. clarae, but differs from the latter by the presence of basifemur II with 5 setae.
Female (Fig. 7–8). (n=6). Dimensions. Idiosoma: length 187(175–200) and width 129(117–150).
Dorsum (Fig. 7 A). The dorsal shield with transverse lobes, except for the region lateral to the sensillae sce, which is smooth. Dorsal shield with one pair each of sensillae vi 63 (60–70); setae ve 20(17–22), setae sci 14(12–17), sensillae sce 72(67–75), c1 12(10–13), c2 13(11–15), d1 12(11–13) and e1 13 (12–15). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur carring setae f1 16(15–17) and f2 11(10–12) each. Setae h1 17(15–20) and h2 9 occur on the integument.
Ve n te r (Fig. 7 B). The propodosomal coxal region is medially completely divided. One pair of paracoxal setae occurs on the coxal region IV. The integument bears 1 pair of propodogastral setae and 3 pairs of hysterogastral setae.
Gnathosoma (Fig. 7 C–E). Hypostome 83(77–87) long with 4 pairs of hg -setae [hg1 8(7–9), hg2 9(8–10), hg3 17(15–20), hg4 7]. Three-jointed palp, 43(42–45) long. Palp tibiotarsi with 3 pointed process. Chelicera 82(77–85) long with cheliceral setae 10(9–10).
Legs (Fig. 8 A–D). Length of legs: I 115(112–125), II 101(97–112), III 112(105–117), IV 130(120–147); length of tarsi: I 42 (40–45), II 33 (30–35), III 29 (25–32), IV 32 (27–35). The leg chaetotaxy is as follows: coxae I—IV, 1 peg, 3 sts—3 sts—3 sts—2 sts; trochanters I—IV, 1 sts—1 sts—2 sts—1 sts; basifemora I—IV, 4 sts—5 sts—3 sts—1 sts; telofemora I—IV, 5 sts—5 sts—1 ms, 3 sts—1 ms, 2 sts; genua I—IV, 3 asl, {1 asl, 1 sts}, 4 sts—2 asl, 5 sts—1 asl, 5 sts—2 asl, 5 sts; tibiae I—IV, 1 asl, 1 bsl, 5 sts—1 bsl, 5 sts—1 bsl, 5 sts—1 T, 4 sts; tarsi I—IV, 2 asl, 2 bsl, 1 dep, 1 dtsl, 2 tsl, 19 sts—1 bsl, 1 tsl, 1 dtsl, 18 sts—1 tsl, 16 sts—15 sts.
Male (Fig. 8). (n=2). Dimensions. Idiosoma: length 221(205–233) and width 115(110–120).
Dorsum (Fig. 8 E). The dorsum is similar to that of the female. Dorsal shield with one pair each of sensillae vi 57 (54–61), setae ve 16(15–17), setae sci 13(12–15), sensillae sce 60(57–64), c1 9(9–10), c2 11(10–12), d1 10 and e1 10 (10–11). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur carring setae f1 13(11–15) and f2 7(7–8) each. Setae h1 11(11–12) and h2 6 occur on the integument.
Ve n t e r (Fig. 8 F). The propodosomal coxal plates fused medially. The integument bears 1 pair of propodogastral setae and 1 pair of paracoxal setae. The genital valves are smaller than those of the females, each bearing 4 g- setae.
Gnathosoma. The gnathosoma is similar to that of the female. Hypostome 70 long with 4 pairs of hg - setae: hg1 7(7–8), hg2 8(8–9), hg3 15 and hg4 6(6–7). Three-jointed palp, 37(35–40) long. Chelicera 63(62–65) long with cheliceral setae 10(10–11).
Legs. Length of legs: I 100, II 87 (84–90), III 101(100–103), IV 108(107–110), length of tarsi: I 36 (35–37), II 29, III 27, IV 29 (28–30). The leg chaetotaxy differs from the female as follows: genua II, 1 asl, 1 bsl, 4sts.
Type material. Holotype female, from soil under Campomanesia sp. (Myrtaceae), 27.VII.2000, Pirassununga, A.R. Oliveira.
