Type material: Holotype ♂: YEMEN / 12 km NW MANAKHAH/ 3.VII-21.VIII.2001 /in Mal. trap/ A. van Harten // Dolichocolon ♂ /det. Th. Zeegers, 2002 [ ZMAN] . Paratypes: Nigeria: 2 ♂♂, NW State,

Etymology: The name paravicinum is a combination of the Greek prefix para -, meaning near, and the Latin adjective vicinum , which is the name of its close relative D. vicinum .

Description: Body length: 7.8–8.2 mm.

Coloration and pruinescence: Head mainly black, covered with whitish-grey pruinescence. Palpus blackish-brown basally shading into yellowish-brown distally. Scape and pedicel fuscous red. Thorax mainly black; posterior 1/2 of scutellum reddish-yellow; scutum with four presutural dark vittae, lateral vitta subtriangular, distinctly outlined and ending wedgeshaped beside posthumeral seta. Legs black. Tegula and basicosta black to dark brown. Abdominal tergites 3–5 with a transverse band of whitish-grey pruinescence (without shifting spots) on anterior 1/2–2/3.

Head ( Fig. 18A View Figure 18 ): Compound eye with short and very sparse ommatrichia at most as long as combined diameter of two facets (visible under> 60 ¥ magnification). Arista thickened on basal 2/5–1/2. Second aristomere 6.6–7.7 times as long as wide. Thickened part of third aristomere 0.63–0.66 times as long as second aristomere. Postpedicel 6.8–7.7 times as long as pedicel. Vertex at its narrowest point about as wide as compound eye in dorsal view. Lateral vertical seta weak, scarcely differentiated from postocular setae. Postocular setae fine, relatively long, curved anteriorly. Six to seven frontal setae descending below level of base of arista. Frontal vitta (measured at midlength between fore ocellus and base of antennae) about 1/2 as wide as fronto-orbital plate (measured at same level). Fronto-orbital plate with one row of medioclinate setae lateral to row of frontal setae. Gena in profile about 0.2 times as high as compound eye. Prementum about 1.0–1.5 times as long as wide.

Abdomen: Syntergite 1 + 2 with one pair of strong median marginal setae. Tergite 3 with one pair of median marginal setae 0.44–0.50 times as long as corresponding tergite. Tergite 4 with a row of eight to nine marginal setae shorter than corresponding tergite. Tergite 5 with a row of marginal and discal setae.

Male terminalia ( Fig. 18B–D View Figure 18 ): Epandrium short and convex. Hypandrial arms slightly bent anteriorly ( Fig. 18B View Figure 18 ). Surstylus short and robust, distal 1/3 strongly bent posteriorly, dorsal surface of distal 1/3 strongly concave, and apically pointed ( Fig. 18B, C View Figure 18 ). Posterior and lateral surface of surstylus covered with long and robust setae ( Fig. 18B–D View Figure 18 ). Medial sclerite of surstylus clearly visible in lateral view ( Fig. 18B View Figure 18 ). Basal 2/3 of cerci prominent and subrectangular in lateral view; distal 1/3 strongly bent posteriorly and widened apically ( Fig. 18C View Figure 18 ).
