Stantonia garamba sp. n.

( figures 13, 16 , 31 , 45 , 83, 85–87 )

Etymology. From the name of the Garamba National Park in the Democratic Republic of Congo.

Type material. HOLOTYPE, „ ( BMNH): Cameroon: Nkoemvon , 17 March–4 May 1978 (D. Jackson) . PARATYPES: Democratic Republic of Congo: PNG [ National Parc of Garamba ], Miss H. De Saeger: „, Makpe/8, 5 November 1951 (H. De Saeger, 2718) ( MRAC). Cameroon: Nkolbison [near Yaounde´]: „, 20 May 1969 (P. Bruneau de Mire´ ) ( CIRAD) .

Holotype, „, length of body 5.6 mm, of fore wing 5 mm.

Head ( figures 83, 85–86 ). Remaining antennal segments 48; length of third segment 1.3 times fourth, length of third and fourth segments 2.7 and twice their maximal widths, respectively; maxillary palp 1.45 times height of head; length of eye in dorsal view 2.5 times temple; temple directly narrowed posteriorly, coriaceous, shiny; eyes shortly setose; OOL: diameter of ocellus: POL~5.0:2.0:4.0; frons and vertex coarsely punctate, laterally rugose-punctate; vertex striate near posterior ocellus; face convex, coarsely striate transversely, with longitudinal median carina; clypeus convex in lateral view and coarsely punctate; length of malar space equal to basal width of mandible; malar suture incomplete, present near eyes; occipital flange straight ventrally and reduced.

Mesosoma ( figure 31 ). Length of mesosoma 1.47 times its maximal height; pronotum crenulate posteriorly, medially crenulate and finely punctate-coriaceous ventrally; mesopleuron coarsely punctate, with some transverse rugae medioanteriorly; precoxal sulcus complete and coarsely sculptured; metapleuron coarsely punctate; metapleural flange small and acute; mesoscutum coarsely punctatecoriaceous, weakly depressed posteriorly at junction of notauli; middle lobe of mesoscutum with a medio longitudinal groove; notauli deeply impressed; scutellum convex, striate-rugose; scutellar sulcus with a median carina; surface of propodeum medially convex in lateral view, with a strong ruga medio-transversely, and several small rugae behind, mid-longitudinal carina present anteriorly ( figure 87 ).

Wings. Fore wing: r: SR1z3-SR~9:36; 2-SR: r-m~9:7; second submarginal cell subsessile ( figure 13 ); subbasal cell glabrous anteriorly ( figure 16 ); vein 3-CU1 as long as vein CU1b. Hind wing: 2-M coloured; membrane glabrous basally.

Legs. Hind coxa coriaceous with transverse rugae dorsally, granulose on medial face ( figure 45 ); length of hind femur, tibia and basitarsus 4.1, 7 and 7.4 times their widths, respectively; tibial spurs 0.4 and 0.3 times basitarsus; hind tibia with four apical teeth.

Metasoma. First tergite 3.6 times longer than apically wide, finely coriaceous and shiny, flattened towards apex in lateral view; spiracles protruding and T1 angled before them ( figure 87 ); second tergite flattened and weakly coriaceous; T2 1.3 times longer than T3; second suture smooth, straight; third tergite shiny.

Colour. Black. Maxillary palp, fore and mid legs (except telotarsus), mandible, labrum, sternites 1–3 yellowish; hind basitarsus and second hind tarsus yellow; brownish; face brownish red; tegulae, telotarsi, triangular patch on epipleuron of T2, setae of second hind tarsus and hind tibial spurs brownish; mandibles apically black; fore wing infuscate apically (0.9 of marginal cell); hind wing infuscate apically.

Variation. Hind tibia spurs yellow; hind basitarsus distally, and the following tarsal articles brownish; second submarginal cell weakly petiolate; mesosoma (except tegulae and apex of rugae on propodeum) yellowish; fore wing apically weakly infuscated; hind wing hyaline.

Remarks. This very distinctive species can be discriminated from the other blackish species by the following characters: no pale medial ring on antenna, coarse sculpture on mesopleuron and striate-rugose scutellum. According to De Saeger (1956), this species was collected near the source of one tributary of Aka River (altitude between 710 and 1000 m).
