description: Erythrogonia hertha Medler, 1963
(Figs 33–45)
Length: female 7.7–7.8 mm (n = 2), male 7.6–8.1 mm (n = 2).
Diagnosis. Head and pronotum dark brown to black, mesonotum red; crown with triangular pale yellow macula contiguous with oval median macula on pronotum (Fig. 33). Forewings (Fig. 33) red with rounded pale yellow macula basally on clavus and corium and with oblique white macula near claval apex; costal margin and basal macula bordered with dark brown to black; membrane dark brown. Male genitalia with styles longer than half length of subgenital plates; aedeagal shaft without processes; dorsal apodemes of aedeagus developed into elongate processes directed ventrally and then posteriorly, as long as pygofer. Female sternite VII (Fig. 35) longer than wide, posterior margin broadly emarginate; sternite VIII (Figs 34 and 35) with pair of striated sclerotized areas; first valvifers (Fig. 36) without processes or additional sclerites; ovipositor valvulae without projections or additional sclerites.
Female genitalia. Sternite VII (Fig. 35) longer than wide, elongate, subrectangular; posterior margin broadly emarginate and with slight notch medially, with pair of small lateral projections; lateral margins slightly concave medially; ventral surface with few irregular striae, without setae; dorsal (inner) surface with pair of transverse elevations along posterior margin, delimiting median sulcus. Sternite VIII (Figs 34 and 35), in dorsal view, with pair of striated sclerotized areas above bases of ovipositor valvulae. Pygofer well produced posteriorly; posterior margin narrowly rounded; macrosetae mostly on posterior half and extending anteriorly along ventral portion. First valvifers (Fig. 36) without processes or additional sclerites. First pair of valvulae (Fig. 36) with basal portion slightly curved dorsally and without projections; sculptured areas (Figs 37–40) as in E. phoenicea and E. calva; dorsal margin approximately rectilinear after basal curvature; ventral margin convex medially; apex acute (Fig. 39); ventral interlocking device (Fig. 36, VID) as in E. phoenicea and E. calva. Second pair of valvulae (Fig. 41) broadened beyond basal curvature, narrowing towards narrowly rounded apex (Fig. 45); ventral margin approximately rectilinear; preapical prominence (Fig. 45) inconspicuous; with approximately 26 teeth; teeth (Figs 42–44), denticles (Figs 43–45), and ducts (Figs 43–45) as in E. phoenicea and E. calva; dorsal dentate apical portion smaller than ventral one (Fig. 45); valvulae without additional sclerites. Gonoplacs as in E. phoenicea and E. calva.
Distribution. Brazil (states of Espírito Santo, Rio de Janeiro, São Paulo, and Santa Catarina).
Material examined. Brazil: state of Rio de Janeiro: one male and two females (MNRJ); state of São Paulo: one female and one male (MNRJ).
