Re-description: Body length: 9.3–10.0 mm. Coloration and pruinescence: Head black, covered with dense whitish-grey reflecting pruinescence. Palpus yellow. Scape and pedicel varying from dark brown to fuscous yellow. Thorax mainly black; posterior 3/4 of scutellum reddish-yellow; scutum with five presutural dark vittae (the middle one very narrow), lateral vitta subtriangular, distinctly outlined and ending more or less wedge-shaped beside posthumeral seta. Tegula and basicosta black to dark brown. Abdominal tergites 3 and 4 with wide bands of whitish-grey pruinescence on basal 2/3–4/5; tergite 5 almost entirely covered with dense pruinescence, except on posterior 1/7–1/5, on which the thin pruinescence turns brownish ( Fig. 17A ). Head: Compound eye bare. Arista thickened on basal 2/5 or slightly more. Second aristomere about seven times as long as wide. Thickened part of third aristomere about as long as second aristomere. Postpedicel about six times as long as pedicel. Vertex at its narrowest point about as wide as compound eye in dorsal view. Lateral vertical seta not differentiated from postocular setae. Six to seven frontal setae descending below level of base of arista. Frontoorbital 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. Postocular setae fine evenly bent anteriorly. Prementum about 1.0–1.5 times as long as wide. Figure 18. Dolichocolon paravicinum sp. nov. A, head in anterodorsal view (paratype: Nigeria); B, terminalia in lateral view (holotype; arrow indicates medial sclerite of surstylus); C, apical portion of surstylus and cerci in laterodorsal view (paratype: Nigeria); D, terminalia in posterior view (holotype). Abdomen: Median marginal setae on syntergite 1 + 2, if present, very short and weak. Tergite 3 with one pair of median marginal setae at most 0.5 times as long as corresponding tergite. Tergite 4 with a row of ten marginal setae. Tergite 5 with a row of marginal and discal setae. Male terminalia ( Fig. 17B–E ): Epandrium short and convex. Hypandrial arms relatively short, not bent anteriorly. Cerci, in lateral view, basally not convex nor protruded, distal 1/3 strongly curved posteriorly ( Fig. 17D ); distal 1/2 of cerci, in posterior view, very narrow ( Fig. 17C ). Surstylus: distal 1/2 strongly bent posteriorly; posterodorsal surface concave and covered with strong erect setae ( Fig. 17B–D ); anteroventral surface with a tuft of long setae ( Fig. 17B–D ); medial basal margin characterized by a wrinkled membrane ( Fig. 17C–E ), which is not visible in lateral view; medial sclerite of surstylus not visible in lateral view. Hosts: Cirphis spp. ( Lepidoptera : Noctuidae ). Distribution: Oriental: India ( Madhya Pradesh , Uttar Pradesh ), Thailand , Vietnam .
