Diagnosis

Males of Hapalopus guidonae sp. nov. can be characterized by the bright orange color on carapace and legs, the abdomen with dark stripes united by a black middle stripe ( Figs 5–6 View Figs 1–10 , 116 View Figs 115–118 ), by the palpal bulb VP with a TK ( Figs 67, 69 View Figs 67–78 ), the PI ring-shaped and apical keel (SA) serrated ( Fig. 70 View Figs 67–78 ). The males differ from H. lesleyae by the absence of PA ( Fukushima et al. 2005: 20, fig. 51; Gabriel 2011: 78, fig. 6). They Differs from H. aymara by the presence of PS, a pronounced VP and by the abdominal striped pattern ( Figs 6 View Figs 1–10 , 116 View Figs 115–118 ; Perdomo et al., 2009: 54; figs 1–6). They Differs from H. serrapelada and H. formosus by the absence of retrolateral keel ( Gerschman & Schiapelli 1973: 71, fig. 79; Fonseca-Ferreira et al., 2017: 186, fig. 18) and the abdominal stripe pattern ( Figs 6 View Figs 1–10 , 116 View Figs 115–118 ). They Differs from H. akroa sp. nov. by the shorter embolus which has the distance between the distal portion of TK and the proximal portion of SA shorter than the length of VP, SA serrated, PI with a discrete denticulate margin, and the abdominal dorsal pattern, with stripes ( Figs 6 View Figs 1–10 , 67–69 View Figs 67–78 ). Females are unknown.

Etymology

The specific epithet is given in honor of the French-Brazilian archaeologist Dr Niède Guidon, and for her fundamental contribution to the creation and preservation of the Serra da Capivara National Park.

Male (holotype CAD 1443)

Color (in alcohol): Carapace, light orange. Chelicerae orange. Legs light orange except by the tarsus and metatarsus dark orange. Dorsal abdomen black with five beige stripes. Mirror patch bright yellow color. Sternum, coxae, labium and maxillae light orange. Ventral abdomen beige with a spot composed by dark bristles ( Figs 5–8 View Figs 1–10 ). Live specimens show brighter brown colors ( Fig. 116 View Figs 115–118 ). Type III urticating setae only, on the central dorsum of the abdomen. Total length: 15.26. Chelicerae basal segment: length 1.66. Carapace elongated: length 9.24, width 7.63. Abdomen: length 6.03. Clypeus absent. Eye tubercle slightly elevated, oval: length 1.2, width 1.52. Anterior eye row slightly procurved, posterior slightly recurved. Eyes and interdistances: AME 0.36, ALE 0.4, PME 0.27, PLE 0.30, AME–AME 0.15, AME– ALE 0.02, ALE–ALE 0.94, PME–PME 0.72, PME–PLE 0.03, PLE–PLE 1.19, AME–PME 0.09, ALE– PLE 0.15. Thoracic fovea slightly procurved, deep: width 1.09. Chelicerae basal segment with 10 well-developed teeth on furrow promargin, with a group of ca 30 small teeth on proximal area of furrow. Intercheliceral tumescence absent. Maxillae with ca 100 cuspules, located on anterior inner corner. Labium subrectangular: length 1.13, width 1.70, with ca 40 cuspules. Sternum slightly round: length 3.88, width 3.57; with three pairs of oval sigilla separated by its diameter from the edge of the sternum.

Palp: Globose tegulum with short embolus ( Figs 67, 69 View Figs 67–78 ); pronounced PI ring shaped, more pronounced than PS ( Fig. 68 View Figs 67–78 ); retrolateral keel absent; SA serrated ( Figs 67, 69–70 View Figs 67–78 ); pronounced VP with a large TK ( Figs 67, 69, 71 View Figs 67–78 ). Cymbium with two asymmetric lobes. Palpal tibia slightly thickened at base, with a TP covered with setae in retrolateral face ( Figs 72–75 View Figs 67–78 ).

Tibial apophysis: composed of two converging branches fused at base ( Fig. 77 View Figs 67–78 ); retrolateral branch longer, slightly curved ( Fig. 76 View Figs 67–78 ); prolateral branch short and thick, slightly recurved with a small apical spine ( Fig. 78 View Figs 67–78 ). Metatarsus I folds between the two branches of the tibial apophysis.

Superior tarsal claws with three small teeth on the midline. Tarsal scopulae: I-II entire with longitudinal band of conical setae; III-IV divided by longitudinal band of conical setae. Metatarsal scopulae not dense, extension: I and II on distal 1/3; III and IV on less than distal 1/3. Clavate tarsal trichobothria in two rows, each with ca 8 trichae, interspersed with ca 10 filiform trichobothria of different sizes. Leg formula 4123 ( Table 3 View Table 3 ).

Spination (proximal to distal): cymbium and tarsi without spines. Palp: femur (p) 1; patella (p) 1; tibia (p) 0-2-3. Leg I: femur (p) 1; patella (p) 1; tibia (p); metatarsus (p) 0-1-1, (r), 1. Leg II: femur (p)1; patella 0; tibia (v) 1-2-ap2, (p) 1; metatarsus (v) 1-1-ap1, (p) 1. Leg III: femur (r) 1; patella 0; tibia (v) 1-1-ap2, (p) 1-1-0, (r) 0-2-ap1; metatarsus (v) 1-1-2, (p) 0-1-1, (r) 1-1-1. Leg IV: femur (p)0-0-1, (r)0-0- 1; patela 0; tibia (v) 1-1-ap2, (p) 1-1-0, (r) 1-2-0; metatarsus (d) 1, (v) 1-1-ap2, (p)1-1-ap2, (r) 1-2-ap3.
