The genus
Unlike most genera of
1 | Size in both sexes moderate (forewing length: >16 mm), forewing antemedial line very faint, if present at all; ventrally, postmedial line on all wings weakly defined, outwardly curved, usually interrupted by wing veins; forewing apex not falcate or if so, weak, blunt. Male genitalia: phallus cylindrical, weakly curved (for example Figs |

– | Size in both sexes relatively small (12 mm [♂], 12–16 mm [♀]), forewing antemedial line present, not faint; ventrally postmedial line on all wings essentially as well defined and following the same pattern as on dorsum; forewing apex sharply acute, falcate. Male genitalia: phallus thin, strongly curved, and hook-like in shape (Fig. |
|
2 | Male: Forewing postmedial line not outwardly lined with black suffusion from tornus to apex. Female: Forewing postmedial line not inwardly lined with light pink-gray suffusion, medial area pink suffused |
|
– | Male: Forewing postmedial line outwardly lined with black suffusion from tornus to apex. Female: Forewing postmedial line inwardly lined with light pink-gray suffusion, medial area largely displaying the light brown ground color, not suffused with pink |
|
3 | Forewing with deep notch at tornus, eastern slopes of the Andes mountains |
|
– | Forewing smooth at tornus, notch absent, west of Andes |
|
4 | Phallus mostly cylindrical in shape, not distinctly broadened distally, found in the Amazon rainforest, moderate elevations of the Andes mountains, or from the Brazilian Atlantic Forest |
|
– | Phallus distinctly broadened distally, endemic to the Cerrado of Brazil and adjacent regions of Bolivia |
|
5 | Forewing postmedial line notched toward costa at intersection with Rs4; forewing narrowed apically, slightly falcate, distributed in the Amazon rainforest and Brazilian Atlantic Forest |
|
– | Forewing postmedial line not notched toward costa at intersection with Rs4; forewing not noticeably narrowed apically, though if somewhat truncated, submarginal area still broader than any other |
|
6 | Setae-filled diaphragmal sacks of male genitalia well developed, extending into body cavity well beyond vincular ring. Pinkish gray suffusion generally broadly distributed in medial area of forewing. Broadly distributed in the Amazon rainforest |

– | Diaphragmal sacks of male genitalia half the size of those in |

We figure and describe the female of this species for the first time, as well as the first Bolivian record. Until now, this species was known only from the male holotype from Maranhão, Brazil. We note some minor external differences between the specimens from drier Cerrado and that of the wet Pantanal, such as the slightly smaller size and brighter coloration in the Pantanal specimen (Fig.
