Diagnosis. Males of G. mazaxoides resemble those G. mboitui and G. karugua by the presence of squamose setae with brachia on the abdomen and coxae II and III translucent white. They share with G. mboitui tibia I ventral spination 3-2 and embolus straight but differs from it by the presence of a long pre-embolar base and the embolus with three keels (pre-embolar base absent and embolus with four-and-a-half keels in G. mboitui; Figs 11A–C, G, 12A–C, G). Differs from G. karugua by the shape of the straight embolus and tibia I ventral spination 3-2 (embolus curved inwards and tibia I ventral spination 3- 3 in G. karugua; cf. Figs 11G and 13G). Females resemble those of G. mboitui by the presence of squamose setae with brachia on the abdomen, tibia I ventral spination 3-2 and coxae II and III translucent white but differs by the CO far anterior to the ST II (CO anterolateral to ST II in G. mboitui) and by the carapace color uniformly black (cephalic area dark and thoracic orange in G. mboitui) (cf. Figs 11H, I and 12H, I).

Description. Male and female. For description of male and female, see Perger & Dupérré (2021).
