Measurements in mm: body length 1.24 (holotype) 1.06–1.35 (paratypes), wing length

1.04 (holotype), 1.07–1.27 (paratypes), wing width 0.44 (holotype), 0.43–0.52.

All body shiny black, microtrichia (tomentum) dark and sparse.

Frontal triangle black shiny, extended to 2/5 of the distance of anterior ocellus to frontal margin, anterior 1/3 of frons dirty yellow, this colour continued laterally to frontal triangle. Palpus slightly longer than flagellomere. Anterior genal setae short and thick, view, 33 = postgonite, lateral view. Scales: 0.2 mm for Fig. 26 View Figs 26–33 , 0.1 mm for Figs 27–33 View Figs 26–33 .

0.055–0.06 mm, medial one slightly more than half as long, lower genal seta comparatively strong upcurved, 0.07 mm. Mostly only 1 more posterior longer genal seta present. Eye 0.21 × 0.155 mm. Gena at lowest point of eye 0.08 mm. Arista 0.14–0.15 mm long with very fine pilosity.

Prescutellar acrostichal pair only 0.05–0.055 mm long, longest anepisternal seta 0.10 mm, longest katepisternal 0.09 mm.

Legs all black. Fore femur with 2 long posteroventral setae.

Wing membrane light yellowish (whitish), veins yellow. Knob of haltere black (actu- ally graphite grey), stalk in the same colour.

Epandrium with a pair of long dorsal setae, 0.11–0.12 mm. Subepandrial sclerite ( Fig. 30 View Figs 26–33 ) broad but not reaching most ventral part of epandrium in caudal view. Epandrium 0.075 mm long, longest caudal seta 0.07 –0.08 mm long but epandrial setae comparatively thick. Anal aperture of epandrium rather large, subcercal part with 2 pairs of short setae. Cercus rather thinly sclerotised. Surstylus ( Figs 31–32 View Figs 26–33 ) large and simple, i.e. broad without an apex; surstylar setae are short both on lateral and medial surfaces. No lamella developed at all. Postgonite ( Fig. 33 View Figs 26–33 ) longer than its basal width, apical part broadly rounded with a small anteriorly curved and not sharp apex.

Etymology. The specific epithet of the new species refers to its black haltere.

Meoneura nigrohalterata   sp. n. is an easily recognisable species. There are but a few species of Meoneura   with dark haltere (see Hennig 1937, SAbrosky 1959). Those two Nearctic species, M. nigrifrons Malloch, 1915   and M. wirthi Sabrosky, 1959   , as well as two Palaearctic species, M. elongella (Zetterstedt, 1838)   and M. perlamellata Hennig, 1937   are not related at all (see SAbrosky 1959: figs 9–10, Hennig 1937: textfig. 70). There is a third species, M. alpina Hennig, 1948   (= M. ungulata Carles-Tolrá et Ventura, 2002   , synonymy by Stuke, 2009), where “Haltere brown”, but its male genitalia are definitely different (CArles- Tolrá & VenturA 2002: fig. 3). This is the first species of this kind in the Afrotropical region. The surstylus of the new species resembles to that of M. scutellata Deeming, 1976   but contrarily to M. scutellata   , its antenna is dark and the knob of haltere in M. scutellata   is white.
