Etymology. From the Latin adjective cancellatus (pied; spotted).

Type locality. Brazil, São Paulo, Santos , without further specific locality data .

Geographic distribution ( Fig. 24 ). Brazil, Rio de Janeiro: Teresópolis, Guapimirim (new record), Itatiaia (new record) ; São Paulo: Santos.

Diagnosis (males). This species can be separated from the other species of the genus by possessing a pair of high and highlighted oval flecks on carapace ( Figs 10A, E ) (in the remaining species it is absent). It can be distinguished from G. angeloi and G. pustulatus by its long femur IV lacking a strong retrolateral row of spines on femur IV ( Figs 11 A–D, 12), as it is characetristic for the mentioned species. It resembles G. bimaculatus and G. pustulosus in having a short femur IV and by the lack of a strong retrolateral row of spines of femur IV ( Figs 11 A–D, 12); it shares with G. pustulosus the presence of a retromedian trifid apophysis on trochanter IV ( Figs 11J, L ).

Redescription. Male (MNRJ 18869).

Measurements. DSL = 9.6 mm, DSW = 9.9 mm, femur IV = 20.7 mm, tibia IV = 14.8 mm, metatarsus = 22.7 mm.

Dorsum ( Figs 10A, E ). Anterior margin of carapace with 10 tubercles; laterally with three on each side; posterior margin with two tubercles; a pair of oval flecks in the lateral side of carapace.Areas I–II with 10 scattered tubercles, III with a pair of paramedian spines. Tiles on areas I–IV large, irregular and slightly fragmented at the edges; area V with a row of 12 tiles (two medium-sized, central). Lateral margins with irregular rows of tubercles. Free tergites I–III smooth, I–II with 11 tiles (two medium-sized, central), III with three tiles (the median one large).

Chelicerae. Movable finger with row of eight teeth, fixed finger with six teeth.

Pedipalps ( Figs 11H, I ). Femur with four ventral and one mesal apical setiferous tubercles; patella ventrally with paramedian apical pair of rows of tubercles. Tibia setation: ectal IiIi, mesal IiIi; tarsus setation: ectal IiI, mesal IiI and armed ventrally with two irregular row of setiferous spines.

Legs ( Figs 11 A–G, J–L, 11). Coxa IV with one retroapical boot-shaped apophysis with heel narrow rectangular and vamp elongate falciform, and one mid-sized (about 2/3 the length of the trochanter IV) straight prolateral short (shorter than the length of trochanter IV) apophysis having a subbasal tubercle ( Figs 11 J–L). Trochanters I–IV with one ventral median tubercle, one retroventral and one proventral apical tubercle, plus one retrobasal and apical tubercle; IV with a retromedian acute apophysis curved frontwards, with an accessory anterior and posterior tubercle, one promedian rounded apophysis ( Figs 11 J–L). Femur IV: long (2.1 times the length of dorsal scutum) and straight; dorsal row with basal DO2 conical, medium-sized (about the same width of trochanter IV), plus tubercles in all extension; proventral row with tubercles, ending with a medium tubercle; retroventral row with tubercles; retrolateral row with spines ranging from small to medium in different lengths; retrodorsal row with tubercles ( Figs 11 A–D, 12). Patella and tibia IV with tubercles. Metatarsus IV unarmed (without row of spines) ( Fig. 11E ). Tarsal segmentation: 6(3)/14(3)/7(3)/8–9(3).

Color ( Figs 10 , 11 , 22C, D). Body and appendages background Strong Brown (55) in alcohol, Deep Orange (51) in vivo with lighter shading on scutal grooves, mesotergum, pedipalps, legs I–III, femur IV distal, patella–tar-sus IV. From coxa IV to proximal 3/4 of femur IV and spines of area III much darker than the general body background Dark Grayish Brown (62) both in alcohol and in vivo. Oval flecks of carapace of male and female Vivid Yellow (82), both in alcohol and in vivo. Tiles of dorsal scutum and free tergites Brilliant Yellow (83) in alcohol, Light Yellow (86) in vivo.

Female (MNRJ 18844) ( Figs 10C, D, F ).

Measurements. DSL = 9.0 mm, DSW = 8.2 mm, femur IV = 10.9 mm, tibia IV = 7.1 mm, metatarsus IV = 12.5 mm. Similar to male, except for coxa IV with prolateral acuminate tubercle; coxa IV with one subbasal, one median and one retroapical tubercle. Pedipalps, tibia setation: ectal IiIi, mesal IiIi; tarsus ectal IiIi, mesal IiI. Tarsal segmentation: 6(3)/12(3)/7(3)/8(3).

Variation. The pustules of the areas I–III and free tergites may vary slightly in size and position in both sexes. Males (n = 65): the posterior margin of carapace can bear a pair of tubercles or one tubercle on either side. Beta male is similar to alpha male, presenting all of the main structures, but with a reduction of the size of dorsal scutum, length of legs and reduction of armature. Females (n = 80): posterior margin of carapace with a pair of tubercles, or one tubercle on the left or right side.
