Type host: Columba l. larvata Temminck. Description Male head with HW , 0.22–0.24 (0.228); HL, 0.54–0.58 (0.560); HL/ HW , 2.07–2.15 (2.11). Thorax with PW , 0.20–0.22 (0.214); MW , 0.25–0.27 (0.260). Genitalia as in Figure 114 ; mesosome with lightly pigmented base; GW, 0.088 –0.098 (0.092). TL, 2.13– 2.33 (2.21). Female HW , 0.29–0.32 (0.303); HL, 0.59; HL/ HW 1.84 – 2.03 (1.94). Thorax with PW , 0.24–0.25 (0.243); MW , 0.29–0.30 (0.297). Ventral terminalia as in Figure 115 ; subgenital plate groove slightly peaked. TL, 2.62–2.67 (2.65) . Material Holotype male, allotype female, 4 male , 2 female paratypes of C. fradei , ex C. larvata , Kenya, Uganda , Principe Island , Lake Tanganyika region (4). Remarks Columbicola fradei has been recorded from both of the disjunct East and West African populations of the type host, C. larvata . The ovoid mesosome of the male genitalia is distinctive. The wide, slightly peaked subgenital plate groove of the female, together with the lack of subgenital plate setae, and overall body dimensions, should allow for reliable identification.
