(Figs. 5–6)
Diagnosis. This species resembles L. martini, but differs from the latter by the presence of a dorsal shield with subcuticular, instead of smooth, punctations, and basifemur II with 5, instead of, 6 setae.
Female (Fig. 5–6). (n=3). Dimensions. Idiosoma: length 231(225–237) and width 173(167–177).
Dorsum (Fig. 5 A). The dorsal shield with subcuticular punctations. Around the sensillae vi is provided by a lobed area. Dorsal shield with one pair each of sensillae vi 72 (67–75), setae ve 37(35–40), setae sci 22(20–25), sensillae sce 75, c1 27(25–30), c2 16(15–17), d1 25(22–27) and e1 25 (20–30). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur carring setae f1 27 and f2 11(10–12) each. Setae h1 21(20–22) and h2 9 occur on the integument.
Ve n t e r (Fig. 5 B). The propodosomal coxal region is completely divided. One pair of paracoxal setae occurs on the coxal region IV. The integument bears 1 pair of propodogastral setae, 6 or 7 hyterogastral setae.
Gnathosoma (Fig. 5 C–G). Hypostome 86(80–92) long with 4 pairs of hg -setae [hg1 10, hg2 10, hg3 21(17–25) and hg4 10] and 2 pairs of adoral setae. Three-jointed palp, 50 long. Trochanter without setae; femorogenu, 6 sts; tibiotarsus, 4 sts, 1 asl terminal, a large bladder-like apophysis and 2 pointed process. Chelicera 89(87–92) long with cheliceral seta 10.
Legs (Fig. 6 A–D). Length of legs: I 141(135–145), II 123(122–125), III 138(137–140), IV 157(155–160), length of tarsi: I 51 (50–52), II 41 (40–42), III 39 (37–40), IV 40. 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—1sts; 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, 4 bsl, 1 dtsl, 1 dep, 2 tsl, 17 sts—1 bsl, 1 dtsl, 1 tsl, 17 (18) sts—1 tsl, 16 sts—15 sts.
Male (Fig. 6). (n=2). Dimensions. Idiosoma: length 175 and width 131(130–132).
Dorsum (Fig. 6 E). The dorsum is similar to that of the female. Dorsal shield with one pair of sensillae vi 67 (65–70), setae ve 33(32–35), setae sci 18(17–20), sensillae sce 66(65–67), c1 22(20–25), c2 13(12–15), d1 21(17–25) and e1 18 (17–20). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur carring setae f1 21(20–22) and f2 7 each. Setae h1 17 and h2 8 occur on the integument.
Ve n t e r (Fig. 6 F). The propodosomal coxal plates fused medially. One pair of paracoxal setae occurs on the coxal region IV. The integument bears 1 pair of propodogastral setae and 1 pair of hysterogastral setae. The genital valves are smaller than those of the females, each bearing 4 g- setae.
Gnathosoma. The gnathosoma is almost similar to that of the female. Hypostome 75 long with 4 pairs of hg -setae [hg1 7, hg2 10, hg3 20 and hg4 8]. Three-jointed palp, 47 long. Chelicera 72(70–75) long with cheliceral setae 7.
Legs. Length of legs: I 125(120–130), II 108(105–112), III 115, IV 134(132–137), length of tarsi: I 47, II 36 (35–37), III 35, IV 36 (35–37). The leg chaetotaxy differs from that of the female as follows: genua I—IV, 2 asl, 1 bsl, {1 asl, 1 sts}, 4 sts—1 asl, 1 bsl, 5 sts—1 asl, 1 bsl, 5 sts—1 asl, 1 bsl, 5 sts; tibiae I, 1 asl, 1 bsl.
Type material. Holotype female, from leaf litter of Myrcia sp. (Myrtaceae), 27.VII.2000, Pirassununga, A.R. Oliveira.
Paratypes. Pariquera- Açu: 1 female, from leaf litter of A. aculeatissimum, 11.VII.2000, A.R. Oliveira; 1 male, from leaf litter of A. aculeatissimum, 11.VII.2000, A.R. Oliveira; 1 female, from leaf litter of A. aculeatissimum, 18.IV.2000, A.R. Oliveira; 1 male, from leaf litter of A. aculeatissimum, 18.IV.2000, A.R. Oliveira.
Etymology. The species designation refers to the substrate litter (- lectus) in which the species was found.
