Neobarombiella budongoensis sp. n.

( Figs 129–132)

Etymology. Named as such because it occurs exclusively in the Budongo Forest, Uganda.

Total length. 3.10–3.90 mm (mean: 3.56 mm) (n=4).

Head. Head, labial and maxillary palpi yellow. Antenna brown, darker from third antennomere to apex, length of second to third antennomere 0.63–0.71 (mean: 0.65), and length of third to fourth antennomere 0.80–0.84 (mean: 0.82) ( Figs 129, 131). Eyes large with short interocular distance ( Fig. 129), width of eye to interocular distance 0.55–0.64 (mean: 0.60).

Thorax. Pronotum yellow, trapezoidal, pronotal width 0.94–1.22 mm (mean: 1.09 mm), pronotal length 0.50–0.64 mm (mean: 0.56 mm), and pronotal length to width 0.48–0.53 (mean: 0.52). Elytron yellow with sharply delimited, very narrow outer elytral and sutural margins, finely and superficially punctuated; elytral length 2.35–3.10 mm (mean: 2.69 mm), elytral width 1.50–2.20 mm (mean: 1.84 mm), and maximal width of both elytra to length of elytron 0.64–0.71 (mean: 0.68) ( Fig. 129). Meso- and metathorax brownish-yellow, legs entirely brown, length of basi-metatarsus to metatibia 0.47–0.55 (mean: 0.50).

Abdomen. Yellowish-brown.

Male genitalia. Median lobe short with V-shaped incision between one pair of sclerotized ridges in ventral view, dorso-ventrally compressed in lateral view, and elongate apically; endophallic brush large, totally covered by tectum and median lobe, with single pair of elongate spiculae ( Fig. 130).

Diagnosis. Neobarombiella budongoensis sp. n. can be characterised by its very narrow outer elytral and sutural margins and superficially punctuated elytra. The rather similar syntopical species N. frohnorum sp. n. has shorter, thicker antennomeres and the ratio of the third to the fourth antennomere differs, 0.63–0.69 (0.80–0.84 in N. budongoensis sp. n.) ( Figs 131, 151). Neobarombiella grotefendi sp. n., also a sympatric species, has elytron with no outer or sutural margins and a very short, characteristic median lobe ( Figs 129, 130, 157, 158).

Distribution. Only known from Budongo Forest in western Uganda.
