description: DOLICHOCOLON CAUDATUM SP. NOV. (FIG. 11A–E)    Type material: Holotype ♂: Senegal: Simenti [13°02′N 13°18′W], /Maribor/ 16.xii.2000 - 1.i.2001 / Nápravnik leg. [SMNS].   
 Etymology: The Latin adjective caudatum is derived from the noun cauda, ae meaning tail, because its long and prominent epandrium is clearly visible in lateral view.   
 Description: Body length: 6.8 mm.   
 Coloration and pruinescence: Head mostly black with gena and parafacial partly reddish, covered with grey pruinescence. Scape brown, pedicel yellow, postpedicel mostly black, yellowish only at base. Thickened part of third aristomere yellow. Palpus yellow. Thorax (except scutellum and postalar callus) black; posterior 2/3–3/4 of scutellum reddish-yellow; postalar callus yellow; scutum with four presutural dark vittae, lateral vitta distinctly outlined and ending wedge-shaped beside posthumeral seta. Legs blackish-brown. Tegula and basicosta black. Abdomen black, more or less reddish laterally on tergites 3 and 4; tergites 3 and 4 with a regular transverse band of whitish-grey pruinescence on anterior 1/2–2/3; tergite 5 pruinose on anterior 3/4–4/5.   
 Head: Compound eye with short and sparse ommatrichia, just visible under 50–60 ¥ magnification. Arista thickened on basal 1/2. Second aristomere about seven to eight times as long as wide. Thickened part of third aristomere about as long as second aristomere. Postpedicel about eight times as long as pedicel. Vertex at its narrowest point 1.1 times as wide as compound eye in dorsal view. Lateral vertical seta only slightly differentiated from postocular setae. Six to seven frontal setae descending below level of base of arista. Fronto-orbital plate with one row of medioclinate setae lateral to row of frontal setae. Gena in profile about 0.25 times as high as compound eye. Postocular setae fine, relatively long, slightly bent anteriorly. Prementum about two times as long as wide.   
 Abdomen: Syntergite 1 + 2 without median marginal setae; general setulae decumbent. Tergite 3 with one pair of median marginal setae distinctly longer than corresponding tergite. Tergite 4 with a row of nine marginal setae. Tergite 5 with a row of marginal setae and several, very short, discal setae.

 Male terminalia (Fig. 11A–E): Epandrial complex prominent in resting position, clearly visible in lateral view from the ventrolateral margin of tergite 5 (Fig. 11A). Epandrium long, convex, and relatively narrow. Hypandrial arms long robust, not bent anteriorly (Fig. 11B). Cerci, in posterior view, wide, relatively short, with brush-like fine medioclinate setulae arising from median slope of a longitudinal carina (Fig. 11C, D), Cerci, in lateral view, not or very slightly bent posteriorly, not widened apically (Fig. 11B); medioventral sclerite not visible in profile (Fig. 11B). Lateral margin of cerci sinuous without a distinct lobe (Fig. 11C). Medial preapical tooth of cerci well developed (Fig. 11E). Surstylus very long, paddle-like, strongly bent posteriorly almost down to the base (Fig. 11B).   
 Hosts: Unknown.   
 Distribution: Afrotropical: Senegal.
