Cimicodes transvolutata Walker, 1860 , List of the specimens of lepidopterous insects in the collection of the British Museum, 20: 40.

Type locality: Brazil. ( NHMUK)

Diagnostic Remarks. Cyphoedma transvolutata is the sole member of the genus found in the Atlantic coastal forests of southeastern Brazil. In males, the underside of the wings exhibits a lighter brown color distally and a more cream color basally, in contrast to C. mirafloresa and C. ashleyorum where these areas are, respectively, characterized by darker brown and whiter colors.Genitalic differences among congeners appear to be too subtle to adequately describe.

Distribution ( Fig. 5 ). So far as known, Cyphoedma transvolutata inhabits the Atlantic coastal forests of southeastern Brazil.

Biology. The immature stages and food plants of C. transvolutata remain unknown. Adults fly throughout the year.

Molecular characterization. No molecular data are available at this time.

Remarks. Walker described transvolutata from a female holotype. This individual was examined by the author in February 2023.
