Diagnosis. Neobarombiella zambiae sp. n. is characterised by its distribution range, small antennomeres, colouring and its superficially punctuated elytra. Only Neobarombiella cornuta sp. n. is rather similar in size and colouring, but has a shorter second antennomere, length of second to third antennomere 0.55–0.60 (0.72–0.80 in N. zambiae); longer third antennomere, length of third to fourth antennomere 0.83–0.86 (0.65–0.74 in N. zambiae) (Figs 139, 191); and larger, less widely separated eyes, width of eye to interocular distance 0.55–0.61 (0.33–0.4 0in N. zambiae)(Figs 137, 189); and is recorded from Cameroon, Guinea and Ivory coast, whereas N. zambiae sp. n. has only been recorded from Zambia and South Africa (Figs 57, 75).

Distribution. Only known from two localities in Zambia and the Limpopo Province in South Africa (Fig. 57).
