Grismadox mboitui Pett et al. 2022: 10 (transfer from Myrmecotypus).

Diagnosis. Males of G. mboitui resemble those G. mazaxoides 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. mazaxoides tibia I ventral spination 3-2 and the straight embolus but differ by the absence of the long pre-embolar base and the embolus with four-and-a-half keels (pre-embolar base present and embolus with three keels in G. mboitui) (cf. Figs 12C, G and 11C, G). Differs from G. karugua by the embolus straight and tibia I ventral spination 3-2 (embolus curved and tibia I ventral spination 3- 3 in G. karugua; Figs 12G and 13G). Females resemble those of G. mazaxoides 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 CO anterolateral to ST II (CO far anterior to ST II in G. mazaxoides) and the cephalic area dark and thoracic orange (by carapace color uniformly black in M. mazaxoides) (cf. Figs 12H, I and 11H, I).

Description. Male and female. For description of both sexes, see Pett (2021).
