Neobarombiella apicalis ( Bryant, 1956) comb. n.

( Figs 109, 117–120)

Ootheca apicalis Bryant, 1956 : [417] 419.

Total length. 4.65–6.85 mm (mean: 5.68 mm) (n=12).

Head. Head, labial and maxillary palpi reddish-brown or brown, frons paler. Antenna slender, pale yellow to brownish, last antennomere either entirely brown or only at apex ( Fig. 117); length of second to third antennomere 0.60–0.75 (mean: 0.67), and length of third to fourth antennomere 0.69–0.83 (mean: 0.76; Fig. 119). Eyes small and widely separated ( Fig. 117), width of eye to interocular distance 0.41–0.53 (mean: 0.48).

Thorax. Pronotum reddish-brown, about 66% of specimens studied with darker brownish patches at lateral basal margins, these rarely joined to form transverse band along basal margin; broad, convexly rounded, and strongly trapezoidal; very finely punctuated, but lacking micro-sculpture, and glossy; pronotal width 1.84–2.46 mm (mean: 2.07 mm), pronotal length 0.86–1.24 mm (mean: 1.02 mm), and pronotal length to width 0.46–0.54 (mean: 0.49). Elytron usually dark metallic greenish, rarely bluey, with non-metallic reddish-brown apical section; distinctly punctuated but lacking micro-sculpture; elytral length 3.75–5.50 mm (mean: 4.41 mm), elytral width 2.40–4.10 mm (mean: 3.00 mm), and maximal width of both elytra to length of elytron 0.62–0.72 (mean: 0.67; Fig. 117). Meso-, metathorax and legs yellowish-brown or yellow throughout, length of basimetatarsus to metatibia 0.38–0.49 (mean: 0.45).

Abdomen. Reddish-brown or entirely brown.

Male genitalia. Median lobe short, broad, almost parallel sided ( Fig. 118), blunt apically with U-shaped incision in ventral view; apical section lacking characteristic sclerotized structures, and elongated ventrally in lateral view; endophallic brush short, covered by tectum and median lobe and lacking spiculae.

Diagnosis. Neobarombiella apicalis can be distinguished effectively from most other species by its size and colouring. It is most similar to N. mendica , and can be distinguished by its shorter antenna and broader basal antennomeres, length of second to third antennomere 0.60–0.75 and length of third to fourth antennomere

0.69–0.83 (the respective data for N. mendica 0.75–0.88 and 0.44–0.57) ( Figs 67, 119). In doubtful cases dissection of the male genitalia allow differentiation, since the median lobe of N. mendica is more distinctly pointed apically and its endophallus displays spiculae ( Figs 66, 118).

Distribution. Recorded from western Democratic Republic of the Congo, through the Albertine Rift region, and single specimens as far as western Kenya and western Tanzania ( Fig. 109).

Type material examined. Lectotype, female: “ Coll. Mus. Congo, Urundi (Mosso): 1450 m., Makoronkwe 12–III–1953, P. Basilewsky / Type / Holotypus / Ootheca , apicalis, Bry., G. E. Bryant det. 195 / R. Det. 6650 J” ( MRAC; Fig. 120). Bryant listed 32 type specimens from four localities in Rwanda and Burundi, and the four specimens from Makoronkwe as “ holotype ”. Since there can only be a single primary type specimen, a lectotype is here designated. Type locality: Burundi, Makoronkwe, 4°12’S / 29°52’E .— Paralectotypes: 3 ex., same label data as lectotype ( MRAC) ; 12 ex., Rwanda, Gitarama , 2°04’S / 29°45’E, 1850 m, I.1953, P. Basilewsky ( MRAC) ; 8 ex., Rwanda, Nduga , 2°25’S / 29°53’E, II.1953, P. Basilewsky MRAC ); and 1 ex., Rukoma , 1°37’S / 29°31’E, I.1953, P. Basilewsky ( MRAC) are paralectotypes .
