Diagnosis.
Suragina milloti is most similar in appearance to other orange-yellow species such as S. agramma , S. copelandi Muller , sp. nov. and S. mulanjeensis Muller , sp. nov. However, S. agramma and S. copelandi Muller , sp. nov. have the notopleural area the same orange-yellow as the rest of the scutum (e. g. Fig. 1 View Figures 1–8 ), whereas the notopleural area between the postpronotal lobe and suture is covered in a dark subrectangular mark with bluish-grey pruinosity in S. milloti and S. mulanjeensis Muller , sp. nov. (Fig. 6 View Figures 1–8 ). Suragina mulanjeensis Muller , sp. nov., however, has its abdominal tergites with dark medial markings compared to the more uniform orange-yellow abdomen of S. milloti . Additionally, S. milloti has the substigmal marking of the wing much darker and more apparent (Fig. 48 View Figures 43–48 ) compared to the other species.
