Neobarombiella zambiae sp. n.

( Figs 57; 189–192)

Etymology. Named after one of the countries in which it occurs.

Total length. 4.10–4.90 mm (mean: 4.51 mm) (n=6).

Head. Head, labial and maxillary palpi yellow. Antenna yellow or brownish-yellow, apex of last antennomere darker ( Fig. 189); length of second to third antennomere 0.72–0.80 (mean: 0.76), and length of third to fourth antennomere 0.65–0.74 (mean: 0.69) ( Fig. 191). Eyes small and widely separated ( Fig. 189), width of eye to interocular distance 0.33–0.40 (mean: 0.36).

Thorax. Pronotum yellow; trapezoidal; pronotal width 1.40–1.74 mm (mean: 1.55 mm), pronotal length 0.72–0.90 mm (mean: 0.80 mm), and pronotal length to width 0.50–0.54 (mean: 0.52). Elytron yellow or brownish-yellow, and superficially punctuated ( Fig. 189); elytral length 3.05–3.90 mm (mean: 3.40 mm), elytral width 1.90–2.70 mm (mean: 2.29 mm), and maximal width of both elytra to length of elytron 0.66–0.74 (mean: 0.69). Meso-, metathorax yellow, legs entirely yellow; length of basi-metatarsus to metatibia 0.43–0.50 (mean: 0.46).

Abdomen. Yellow.

Male genitalia. Median lobe long, parallel sided with small V-shaped incision, flanked by one pair of long sclerotized ridges, in ventral view ( Fig.190b); apex elongate and dorso-ventrally compressed in lateral view ( Fig 190c); endophallic brush small, covered by tectum and median lobe, with single insignificant pair of spiculae ( Fig. 190).

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).
