Males of G. karugua resembles those of G. mazaxoides, and G. mboitui by the presence of squamosa setae with brachia in the abdomen and coxae II and III translucent white but differs by the embolus curvate (straight in G. mazaxoides, and G. mboitui), four keel (three in G. mazaxoides and four-and-a-half in G. mboitui) and tibia I ventral spination 3-3 (3- 2 in G. mazaxoides and G. mboitui) (cf. Figs 13A–C, G with 11 A–C, G and 12A–C, G). Females resemble those of G. mazaxoides, and G. mboitui by the presence of squamosa setae with brachia in the abdomen but can distinguished by the tibia I ventral spination 3-3 (3- 2 in 3- 2 in G. mazaxoides), coxae IV darker (translucente white G. mazaxoides and G. mboitui, and by parallel position of CD vs diagonal position in G. mazaxoides and G. mboitui) (cf. Figs 13D–F, H, I with 11 D–F, H, I and 12D–F, H, I).
