Diagnosis. Neoceratitis can be separated from morphologically similar genera by the combination of the following diagnostic characters: arista pubescent; scutum with dark brown to black ground colour, with central silver-grey microtrichia forming a characteristic pattern with anterior and posterior extensions and shining round patch at mesal end of transverse suture; scutellum convex or partially flattened, with variable black and white pattern; wing with dark brown banded pattern consisting of an anterior apical band, a posterior apical band (see also description below), a discal band, and a subapical band (sensu banding in Ceratitis , cf White et al. 1999, figure 33.3c), basal area brownish and subbasally continued as series of darker spots and streaks as observed in other ceratitidine genera. Female aculeus usually simply pointed, at most tip with subapical steps.

Description. Head. First flagellomere twice to three times as long as pedicel; yellow to brownish; rounded apically. Arista short to moderately long pubescent along entire length. Frons yellow, sometimes with darker markings. Face entirely white, or white with darkish markings; in lateral view largely straight to concave. Chaetotaxy: major setae black and acuminate; two orbitals, anterior orbital thicker and longer than posterior orbital; two frontals, anterior frontal slightly shorter than posterior frontal; one pair of ocellars, as long as or longer than anterior orbital; medial vertical at least twice as long as posterior orbital, lateral vertical equal to posterior orbital seta; postocellar black, shorter than lateral vertical; postoculars slender and short, black. Genal setulae usually well developed, black. Genal seta black. Other setae and setulae short and black or whitish-yellow.

Thorax. Postpronotal lobe white, or white with anterior part black-brown. Scutum wider than long or as long as wide; shining black-brown; with short dark setulae; centrally with large area with silver-grey setulae and microtrichia; microtrichia pattern ( Fig 1 View FIGURE 1 c) anteriorly extending to scapular setae, along pair of submedial lines, in medial part only extending to halfway between transverse suture and scapular setae; posteriorly extending to scutellum in medial part for width equal to distance between prescutellar acrostichal setae, sublaterally usually almost extending to intra-alar seta; microtrichia lacking near medial end of transverse suture where round shining black spot present; sometimes microtrichose pattern reduced or different ( Fig. 1 View FIGURE 1 a–b). Scutellum usually rounded and swollen, rarely somewhat flattened; white or with black apical marking(s) that can extend to anterior margin ( Fig. 2 View FIGURE 2 ). Subscutellum entirely brown. Anepisternum variable, either largely brown or brown with posterodorsal area white, white area usually touching postpronotal lobe and dorsal margin, ventrally extending obliquely to posteroventral corner or almost so. Katatergite and anatergite variable, usually partly or wholly white to yellow, sometimes brownish. Chaetotaxy: setae on scutum normal in shape and usually black; two scapulars, one postpronotal, two notopleurals, one presutural supra-alar, one dorsocentral, one postsutural supra-alar, one postalar, one intra-alar, one prescutellar acrostichal, one basal and one apical scutellar, one anepisternal, one anepimeral, and one katepisternal.

Legs. Yellow; femora sometimes darkened. Setae black, setulae yellow to black. Midtibial spur black.

Wing. Vein R4+5 dorsally sparsely setulose on basal two-thirds. Vein M reaching costa posterior to wing apex. Cell bcu with posterodistal lobe sinuous. Wing banding brown and similar to pattern observed in Ceratitis species ( Fig. 3 View FIGURE 3 ), with discal, anterior apical, posterior apical and subapical bands present, although latter two appear to be completely merged with each other in one species. Subapical band isolated or connected to discal and/or anterior apical band. Basal area of wing largely brownish, but not forming distinct band; continued subbasally with brownish streaks and spots.

Abdomen. Ground colour usually brown to black, rarely reddish; with black setulae, usually with longer setae along posterior margin of tergites. Tergites 2 and 4 often with paler transverse band and pale setulae. Male terminalia, surstyli ( Fig. 4 View FIGURE 4 ), lateral surstylus usually with anterior lobe short; prensisetae in lateral view largely obscured by lateral surstylus. Female terminalia, oviscape black to brown, shorter than length of abdominal tergites 1-5 combined; with short, dispersed blackish setulae. Aculeus elongated or short ( Fig. 5 View FIGURE 5 ) flattened; aculeus tip usually simply pointed or with weakly developed subapical steps ( Fig. 6 View FIGURE 6 ).
