Catanduba piauiensis View in CoL sp. nov.
Figs 8 View FIGURE 8 A–D
Type-material. Holotype: male from Campus da Embrapa, Teresina, Piauí, Brazil, (5°09'S; 42°46'00"W), 15/IV– 01/VI/2005, A. dos Santos Rocha col., deposited in IBSP 13747.
Etymology. Named after the state of type-locality, Piauí, Brazil.
Diagnosis. Males of Catanduba piauiensis sp. nov. differ from those of other species by the presence of an auxilliary keel under PIK with a pointed apical edge, also present in C. araguaia ( Figs 8 View FIGURE 8 A–C). They differ from males of C. araguaia , by the stronger auxiliary keel, weaker PSK and absence of tip curvature on the metatarsal I basal nodule ( Fig. 8 View FIGURE 8 D).
Description. Male (Holotype). Color in alcohol: carapace and legs reddish brown. Abdomen dorsally dark gray with five strips extending to laterally and ventrally light brown. Urticating hairs of type III. Total length, without chelicera, 16.96. Carapace: length 8.88; width 7.12. Eye tubercle: length 1.18; width 1.36. Eyes size: AME 0.36, ALE 0.44, PME 0.21, PLE 0.30. Labium: length 1.13; width 1.50. Sternum: length 4.75; width 3.69. Basal segment of chelicera with row of 9 teeth on prolateral margin and group of 16 small teeth concentrated on basal third. Labium with 51 cuspules. Endites with ca. 129 cuspules. Palp: femur 4.88/ patella 3.12/ tibia 4.16/ cymbium 1.60/ total 13.76. Leg I: femur 7.76/ patella 4.16/ tibia 5.76/ metatarsus 5.60/ tarsus 3.92/ total 27.20. II: 7.28/ 4.24/ 4.88/ 5.04/ 4.08/ 25.52. III: 6.08/ 3.44/ 4.00/ 5.52/ 3.84/ 22.88. IV: 7.68/ 3.84/ 5.92/ 8.00/ 4.56/ 30.00. Spinnerets: basal segment 1.76; medium 0.92; apical 1.00. Spination: Palp: femur d0-0-1p, tibia v0-1p-1p; p 0-1-0; Leg I: femur d0-0-1p, tibia v2-2 -0-1ap, p1-0-1; II: femur d0-0-1p, tibia v1-2 -0-2ap, p1-0-1, metatarsus v2-1 -0-1ap, p1-0-0; III: femur d0-1p-2, patella p0-0-1, r0-0-1, tibia v2-3 -0-3ap, p1-0-1, r1-0-1, metatarsus v2-2 -1p-1ap, p1-1-1, r1-0- 1. IV: femur d0-0-2r, tibia v1-2 -1p-1ap, p1-0-1, r2-2-1, metatarsus v1-2 -2-3ap, p0-1-1, r1-1-1. Scopula: Metatarsus: I with 0.42 of total length scopulated, II with 0.46, III with 0.31 and IV with 0.27. Tarsus: I undivided, II divided by 1–2 rows of stronger setae, III divided by 2 rows of stronger setae and IV by 4. Palpal bulb with PIK and PSK well developed. PSK curved for half of its length. Thin embolus with tooth emerging from PIK. Additional keel under PIK with pointed end. Small weak grooves between PIK and PSK and above last one. Digitiform apophysis present ( Figs 8 View FIGURE 8 A–C). Tibial apophysis formed by two branches with distinct bases: prolateral smaller, with retrolateral spine; retrolateral larger. Metatarsus I with strong basal triangular nodule and flexes between tibial apophysis branches, touching their median portion ( Fig 8 View FIGURE 8 D).
