Heteragrion flavovittatum Selys 1862: 20–21 [18–19 reprint] (description of male and female); Selys 1886: 56 (species diagnosis); Williamson 1919: 15, Figs. 12–13, 119–120, 133 (discussion of MCZ specimens illustration of head of male and female, male appendages in dorsal and lateral views, male prothorax in dorsal view); Lencioni 2005: 131, Figs. 80A– C (description and distribution, illustration of male syntype appendages in dorsal and lateral view, habitus and thorax in lateral view); Machado & Bedê 2006: 50–52 (differences from H. muryense , H. petiense , H. ovatum and H. tiradentense ); von Ellenrieder & Garrison 2007: 6, Fig. 2e (mention and illustration of male appendages); Garrison et al 2010: 88–91, Figs. 89, 91 (list, illustration of wings and appendages in mediodorsal view).

Types. Male syntype in IRSNB (examined), and male and female syntypes in MCZ. Male examined with the following labels: "mg [manuscript black ink on dark blue paper]", " H. flavovittatum DS ♂ Minas Gerais [manuscript black ink on pale brown paper]", " H. flavovittatum [manuscript black ink on pale blue paper]" and " Dessiné Williamson " [manuscript pencil on white paper]" .

Additional material examined. 1♂ directly compared with syntype. Brazil: Minas Gerais State: Jaboticatubas, Serra do Cipó —km. 128, 31-X-1966 , 1♂, leg. N. Santos, J. Machado & J. Martins. Images of a female collected near Santa Barbara, Minas Gerais State ( Figs. 48A–C, 50E–F, 56B) .

Illustration made from following specimens. 1♂ —(Fig. 15A, 15B, 34A, 34B, 34C, 54A) Brazil: Minas Gerais State: Jaboticatubas, Serra do Cipó —km. 128, 31-X-1966, leg. N. Santos, J. Machado & J. Martins ( NC 1962 ); images of a female collected near Santa Barbara, Minas Gerais State (Fig. 46A, 46B, 46C, 48E, 48F, 54B), kindly provided by R. W. Garrison .

Distribution. Brazil (Minas Gerais State).

Diagnosis. Male: Easy to recognize by mostly black dorsum of thorax (Fig. 34B—shared with H. muryense and H. tiradentense —but these two species have the mesepisternum interrupted by a pale spot) and strongly swollen base of cercus occupying 2/3 of its length (Fig. 15B). Cercus in lateral view: dorsobasal expansion present. Ventrobasal expansion very large, occupying 2/3 length, its ventral margin almost straight (Fig. 15B). Cercus in mediodorsal view: Basal, medial and apical portions of cercus subequal. Ventral expansion present and sparsely hairy. Ventral branch of medial process rectangular plate with apical end rounded, dorsal branch roughly triangular and fused with ventral branch on its inner side (Fig. 15A). Female: Posterior lobe of prothorax semicircular with small notch in middle, pale yellow with large ovoid black spot in middle bordered with brown and tips covered with short hairs (Fig. 46C); valves of ovipositor reaching but not surpassing distal S10 and in lateral view ventral margin with small spines ( Fig. 48E); Cercus subequal to S10, apparently without bristles at the tip ( Fig. 48E); Basal plate: dorsal edge an inverted S-shape, longer than convex outer edge. Ventral side 2/3 length of outer edge ( Fig. 48F).
