Types. ♂ holotype from Estuaire, Ntoum (00°23’N, 09°47’E), GABON, 5–15.X.1985, leg. A. Pauly (pelouse jardin, bac d’eau) ( MRAC 172.929 ) ; ♀ paratype from Kwango: Feshi , environs 15 Km. Et droite de la route vers Popokabaka [06°07’S, 18°10’E], DEMOCRATIC REPUBLIC OF THE CONGO, 850 m.a.s.l., III.1959, J. Leleup leg. (Forêt marécageux de la tête de source de la Kikoli) ( MRAC 154.508 ).

Etymology. The specific name is a noun in apposition referring to Patrice Émery Lumumba, first Prime Minister of Democratic Republic of the Congo, after its independence from Belgium.

Diagnosis. Males of Carteronius lumumba sp. nov. resemble those of C. sudanus comb. nov. by the absence of a retrolateral apical tegular process and by the bifid tip of the embolus ( Figs 4A , 16B ), but differ by the narrower proximal half of the embolus and by the long spermatic duct, which touches the apical margin of the bulb ( Fig. 16B ). Females of C. lumumba sp. nov. are similar to those of C. simoni sp. nov. by the inconspicuous lateral plates of the posterior epigynal sector ( Figs 16D , 17C ), but can be recognized by the narrower, convergent copulatory ducts ( Fig. 16D ).
