Diagnosis: Differs from G. marginalis, G. dimorpha and G. orensis by having DS entirely coloured with a reticulate pattern that penetrates the areas of scutum and great part of carapace (Fig. 52D).
Distribution: It is distributed in the Brazilian States: Pará, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Bahia, Espírito Santo and Minas Gerais. Ecoregions: Xingú-Tocantins-Araguaia moist forest, Caatinga, Atlantic Coast restingas, Pernambuco Coastal forest, Pernambuco interior forest, Bahia interior forest, Bahia coastal forest and Atlantic dry forest. The species was also found in Floriano and Teresina cities of Piauí State (Leonardo Carvalho (CHNUFPI), pers. comm.), although these records are not included on the map (Fig. 48).
Description of male MNRJ 41773 (with extra figures from other specimens): Measurements: CL: 1.45, CW: 2.20, AL: 3.17, AW: 3.98, IOD: 0.70, FeIV: 9.28.
Dorsum (Fig. 52). DS beta-type with attenuate constrictions and provided with notable scattered granules. Area I with low tubercles and area III with long spines. Dorsal scutum, in lateral view, rising steadily from posterior and anterior borders to area III where it is the highest height. Scutal grooves effaced. Anterior edge of dorsal scutum with protoglyphs slightly concave with lateral triangular borders. Ocularium low, with a few granules near the eyes. Posterior border and free tergites each containing a transverse row of minute granules, anal operculum with scattered granules. Coda reduced.
Venter (Fig. 52B). Coxae I– III triangular, transverse to main body axis. Coxae II – IV connected by tubercular bridges. Coxae I– II with a longitudinal row of granules. Coxa IV pentagonal, greatly developed, oriented obliquely, but almost parallel to the body axis. Stigmatic area T-shaped with stigmata large, unconcealed. Free sternites each with a row of granules.
Chelicerae (Fig. 53E, F). Hand not swollen. Basichelicerite short, with well-marked bulla and uniformly tuberculated dorsally. Posterior and ectal margins of bulla are fringed with several tubercles, posterior ones are the largest. Movable finger of cheliceral hand with ten truncate tubercles. Fixed finger with five triangular tubercles.
Pedipalps (Fig. 53G, H). Elongate trochanter, foliaceus femur; convex dorsally, with a dorsal row of five fused setiferous tubercles forming a keel and a ventral row of 14 setiferous tubercles. Tibia only slightly convex in ectal border, with one lateral row of setae in each side, distalmost setae of each side larger than others. Tarsus conical, with scattered dorsal setae and three well-marked ventral rows of subequal setae, prolatero-ventral row with two larger setae, one apical and one one median region.
Legs (Fig. 52). Long and unarmed legs, femora straight. Coxa IV convex in dorsal view with few apical granules, no clavi inguines. Pectinate claws in legs II and IV in two rows. Tarsal counts: 8, 17, 10, 11 (Sørensen in Henriksen, 1932).
Colour (in alcohol, Fig. 52). Dorsal scutum and coxae brilliant orange-yellow (67). Reticulate pattern in almost the entire DS (excepting anterior region to ocularium) pale greenish-yellow (104) more marked as laterals of chevron near the carapace. Appendages podomeres (except coxae) brilliant greenish-yellow (98).
Penis (Fig. 53A–D). Ventral plate short trapezoidal, wider at the base, with straight distal margin. Sub-distal lateral margin of VP with three pairs of MS-C, large, curve and flattened. Two pairs of MS-D located in apical half of VP, MS-D1 twice longer than MS-D2 and closer to MS-C2, both MS-D straight and conical. Two pairs of MS-A in the basal region in VP, straight, conical and as long as MS-D1. Two pairs of MS-E in apical portion of latero-ventral surface and one pair of MS-B in the basal portion of ventral surface of VP. Ventral surface with two lateral thick stripes composed with microsetae type 4 (T4) surrounding MS-B and MS-E, gently advancing into the truncus. Glans with rounded dorsal process, stylus with a wattle extending to the base, with an extended serrate part and without stylar barbs.
Variation. Reticulate pattern varies from a well-filled form to a reduced form in mesotergum and carapace, but always is well marked as ears of chevron. It is possible to differentiate two types of males: (1) major forms, with long tibiae and short metatarsi and (2) minor forms, with shorter tibiae and longer metatarsi, more similar to females. This is depicted in Fig. 50D–H for G. dimorpha. Tarsal counts: 6–8, 12–17, 8–10, 8–11. (Sørensen in Henriksen, 1932, Mello-Leitão, 1936 and Mello-Leitão, 1944).
