The most similar species is <i>B. bivittata</i> Lin & Wang, but <i>B. melanobivittata</i> can be distinguished by having a scutum that is almost completely black except for two longitudinal red stripes, and the yellow postsutural vittae. There is intraspecific variation in the amount of black on the scutum in <i>B. bivittata</i> (Fig. 3) but the red stripes are obscured in darker colored specimens of <i>B. bivittata</i> whereas they are of roughly equal width and clearly contrasting in <i>B. melanobivittata</i>. <i>Bactrocera melanobivittata</i> can be distinguished from <i>B. ellenriederae</i>, which also has two red stripes on the scutum, by the costal band on the wing that ends between vein R 4 + 5 and M, while the costal band of <i>B. ellenriederae</i> reaches vein M, and <i>B. melanobivittata</i> is distinguished from <i>B. youngi</i> by having only the anterior lateral corners of tergite IV black, whereas <i>B. youngi</i> has the lateral quarters of tergite IV black.

Fulvous with oval black spots in the antennal furrows. Antennal segments fulvous to dark fulvous distally, combined length less than the height of the head. <i>Thorax</i> (Fig. 2 A, B, D, E). Scutum and pleural areas all black with narrow red-brown areas surrounding the yellow markings. Two lateral longitudinal red stripes reach from the anterior of the scutum to half-way of the postsutural yellow vittae. Yellow markings: postpronotal lobes; notopleura; presutural area adjacent to notopleura; postsutural yellow lateral vittae of equal width throughout and reach just past intra-alar seta; mesopleural stripe dorsally wider than notopleuron but does not reach postpronotal lobe; anatergite and katatergite. Scutellum yellow with a narrow black basal band. Setae: one pair scutellar; one pair prescutellar; one pair intra-alar; one pair posterior supra-alar; one pair anterior supra-alar; two pair notopleural and four scapular. <i>Abdomen</i> (Fig. 2 B, D, E, G). Diamond-shaped; terga free; pecten of setae on tergum III present. Dorsal side of abdomen fulvous with a black ‘ T’ on segments III – V, the medial line narrows posteriorly to a point on segment V. Anterolateral corners of segment IV black. Ceromata brown. Posterior lobe of the male surstylus short (Fig. 2 G). Sternum V with a narrow concavity on the posterior margin. <i>Legs</i> (Fig. 2 D). All femora and tibia fulvous. <i>Wings</i> (Fig. 2 F). Wing length 6.5 mm. Cells <i>bc</i> and <i>c</i> clear, faint tint in cell <i>sc.</i> Costal band confluent with vein R 2 + 3 and continues at more or less the same width until just past where vein R 4 + 5 reaches the costa.
