( Figs. 9−14 View FIGURE 9 View FIGURE 10 View FIGURE 11 View FIGURE 12 View FIGURE 13 View FIGURE 14 )

Diagnosis. The new species is related to Griphophanes congoensis sp. nov., differing from the latter in the apical part of wing vein CuA1 slightly shorter than dm-cu and male segment 7 is very long, nearly as long as terga 4−6 combined (see the key below).

Type material. HOLOTYPE 3, [ DR Congo:] Congo Belge, P.N.G. [Parc National de la Garamba], Miss. H. De Saeger, Ndelele, 23.VII.1952, H. De Saeger, 3815 [ RMCA]. PARATYPES: 13, same as holotype; 13, same as holotype with collection date 30.VII.1952, 3849 [ RMCA].

Etymology. The species is named for the region of origin.

Description. Male: Head: Frons and face with black ground colour; frons shining violet, weakly brownish pollinose; face whitish pollinose. One strong vertical seta at upper corner of frons; one hair-like postvertical seta positioned behind vertical seta; 2 ocellar setae strong; two short fine postocellars; postocular setae mainly white, several upper setae black. Eyes haired. Face under antennae as wide as height of postpedicel, distinctly depressed and narrowing in middle half. Antenna black, as long as head height. Scape small, vase-like; pedicel larger, globular, with ring of short setulae and 1−2 elongate apicodorsal setae; postpedicel subtriangular, as long as high at base, densely haired; stylus middorsal, 4 times as long as main segments of antenna combined, pubescent, with short thick segment 1 and filiform segment 2. Ratio of lengths of scape to pedicel to postpedicel to stylomere 1 to stylomere 2: 2/3/ 5/2/45. Palpus and proboscis small, blackish-brown, palpus oval, whitish pollinose, with black seta and dark pubescence.

Thorax: Mesonotum shining violet-black, weakly grey pollinose, with dark bristles; pleura greenishblack, whitish pollinose; mesonotum flattened posteriorly. Six (2+4) dorsocentrals, with 1st seta short and 6th seta shifted towards lateral margin; short acrostichals in two irregular rows; scutellum with one pair of strong setae and one pair of short lateral setae. Upper propleuron without setae; proepisternum with 1 strong seta. Legs: Blackish brown with knees and trochanters light brown. All tarsi simple, with 5th segment flattened dorso-ventrally, with well developed pulvilli and claws. Fore and mid coxae with dark anterior and apical setae; hind coxa with 1 dark bristle at middle. Fore leg without strong setae; fore tibia with 1−2 weak apicals, fore tarsomeres 2−4 dorsally with elongate setulae. Length ratio of fore tibia to tarsus (segments from first to fifth): 57/30/ 15/12/8 /9. Mid femur simple, bearing 1 strong but short anterior subapical bristle; mid tibia simple, with 1 anterodorsal and 1 posterodorsal setae at basal third, 1 anterodorsal at distal third and 3 apical setae; no ventral setae; mid tarsus simple; segments 1–4 each with short apical spinules; segments 4–5 with elongate setulae. Length ratio of mid tibia to tarsus (segments from first to fifth): 66/35/ 17/12/7 /8. Hind femur with 1 anterior subapical bristle, with elongate dorsal setulae at base; hind tibia simple, with 1 dorsal and 1 anterodorsal setae at basal fourth, 1 dorsal and 1 anterodorsal setae at distal third, 1 subapical anterior, 1 apicoventral setae, with strong subapical dorsal bristle, half as long as hind basitarsus and with elongate dorsal setulae in distal third; hind basitarsus with 1−2 short apicoventral setae, with very small basal tooth posteriorly. Length ratio of hind tibia to tarsus (segments from first to fifth): 68/18/ 17/11/7 /8. Wing: Greyish, veins brown. Costa simple, with simple costal setulae reaching R2+3. Ratio of part of costa between R2+3 and R4+5 to that between R4+5 and M1+2: 17/11. R2+3 and R4+5 slightly diverging towards wing apex; R4+5 slightly convex anteriorly, and M1+2 straight, parallel to R4+ 5 in distal half. Ratio of apical to basal part of M1+2, 78/53. Ratio of dm-cu to apical part of CuA1: 15/11. Anal vein distinct, weak at apex, running close to wing margin; anal lobe not developed. Lower calypter small, brown, with black setae. Halter knob yellow.

Abdomen: Conoid, 1.6 times longer than thorax, shining dorsally, whitish pollinose laterally, with black hairs and marginal setae, longish on 1st tergum; terga 1-3 bluish-green; terga 4−6 blackish-green; sterna invisible. Tergum 6 as long as tergum 5, half-concealed, glabrous; segment 7 black, long and thin, nearly as long as terga 4−6 combined, densely covered with very short hairs, with subequal tergum and sternum; segment 8 brown, large, covered with microscopic hairs, with long ventral inverted “Y” shaped sclerotized process; hypopygium black, with brown appendages; epandrium globular, asymmetrical, slightly longer than high; foramen lateral, shifted ventrad; hypandrium fused with epandrium at base with distinct suture, short, flat, with deep excavation distally; phallus thin and long; distal epandrial corner with 1 large and 1 small flat lobe and with 1 finger-like process bearing apical seta; large epandrial lobe with marginal setulae and 2 strong setae; surstylus symmetrical, adjacent to cerci, with dorsal arm shorter than ventral one, both finger-like; ventral arm of surstylus angular apicodorsally, with few minute setae at apex; dorsal arm with narrow apex, bearing 4 strong apicoventral and apicolateral setae, of which inner seta longest; cercus small, shorter than surstylus, with short dorsoapical projection, sparsely microscopically haired, bearing 2 strong apicoventral setae and 1 apicodorsal spine.

Measurements (mm): Body length 2.4, antenna length 0.7, wing length 2.4, wing width 0.7, hypopygium length 0.4. Female. Unknown.
