Frequently considered conspecific with E. astrild, and in HBW mentioned as being embedded in single clade with all other races, and as being genetically nearly identical to E. a. adesma and E. a. cavendishi (which it replaces along R Lualaba), and slightly more different from E. a. rubriventris and E. a. occidentalis. Nevertheless, differences notable, involving narrower, shorter, black vs broader, longer, red mask (3, arguably 4); narrow pinkish-white line above lores (1); greyish vs white cheeks (1); and shorter, stubbier bill (mean length of three males, two unsexed and one female 8.6 mm vs 9.4 in E. a. adesma, n=10, and 9.3 in E. a. cavendishi, n=10; allow 2). Monotypic.
