Diagnosis
Diagnosis. This species resembles P. franciscae, but differs from the latter by the presence of 4 solenidia on genua I instead of 3.
Description
Female (Figs. 3–4) (n= 13). Idiosoma: length 252 (237–287) and width 176 (150–212). Dorsum (Fig. 3 A). Dorsal shield slightly punctated with sensillae (vi and sce) setose; dimensions: vi90 (80–107), ve23 (20–27), sci16 (12–22), sce78 (67–87), c 1 12 (10–15), c 2 12 (10–12), d 1 13 (10–17) and e 1 15 (12–17). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur that carring setae f 1 19 (15–22) and f 2 11 (10–12) each. Setae h 1 22 (17–25) and h 2 13 occur on the integument. Ven t er (Fig. 3 B). The venter resembles that of P. myrtaceus sp. nov., but with 7 or 8 hysterogastral setae. Gnathosoma (Fig. 3 C–D). Hypostome 117 (100–127) long, bearing 4 pairs of hg setae [hg 1 11 (10–15), hg 2 13 (10–17), hg 3 35 (30–37) and hg 4 10 (7–12)] and 2 pairs of adoral setae. Three- jointed palp, 74 (62–87) long. Trochanter without setae; femorogenu, 6 sts; tibiotarsus, 4 sts, 1 asl terminal, 1 bladder-like apophysis and 1 ventral pointed process. Chelicera 116 (105–120) long with cheliceral seta 7. Legs (Fig. 4 A–D). Length of legs: I 165 (145–197), II 140 (120–170), III 158 (142–195), IV 171 (155–202); length of tarsi: I 62 (55–72), II 47 (40–60), III 44 (37–50), IV 45 (37–52). 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— 6 sts— 3 sts— 2 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— 1 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, 1 asl, 3 bsl, 1 dep + peo, 1 dtsl, 2 tsl, 22 sts— 1 bsl, 1 dtsl, 1 tsl, 19 sts— 1 tsl, 16 sts— 17 sts. Male (Fig. 4). (n= 3). Dimensions. Idiosoma: length 191 (175–212) and width 143 (135–165). Dorsum (Fig. 4 E). The dorsum is similar to that of the female; dimensions: vi85 (77–90), ve25 (22–27), sci16 (15–17), sce75 (72–80), c 1 12, c 2 12 (10–12), d 1 12 and e 1 12 (12–15). Posteriad to the dorsal idiosomal shield one pair of tiny platelets occur carring setae f 1 15 and f 2 8 (7–10) each. Setae h 1 17 and h 2 13 occur on the integument. Ven ter (Fig. 4 F). 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 3 pairs of hysterogastral setae. Paragenital setae are not present. The genital valves are smaller than those of the females, each bearing 4gsetae. Gnathosoma. The gnathosoma is similar to that of the female. Hypostome 105 (100–112) long with 4 pairs of hg -setae [hg 1 13 (12–15), hg 2 15 (15–17), hg 3 38 (35–42) and hg 4 10] and 2 pairs of adoral setae. Threejointed palp, 74 (70–77) long.
