Eacles guinlei Oiticica Filho, 1941

Figs 9a–b, 10a–b, 11 ; 12 (map)

Diagnosis. Male ( Figs 10a–b, 11 ): as stated by Oiticica Filho (1941), males of E. guinlei are easily recognized by the more elongated FW (ratio length/width: 2–2.2; males of other species of the masoni -group of species: 1,8–1,9), the antemedian area of the HW apart of the postmedial line, and attributes in the male genitalia. Female ( Figs 9a–b ): the dorsal brownishred background is only present on the FW, while all the other females of the masoni -group of species are either entirely yellow sprinkled with black dots or covered with brown on both fore- and hindwings (see Lemaire 1988: Pl. 11, Fig. 4 ; Pl. 12, Figs 2–3 ).

Remarks. Since Lemaire (1979), Eacles guinlei had been maintained as a synonym of Eacles masoni fulvaster Rothschild, 1907 , but Brechlin & Meister (2011: 31) revised its taxonomic position and revalidated it as a full species without explanation. In the same article, these authors elevated E. masoni fulvaster to species level and considered E. masoni Schaus as a distinct entity. Eacles guinlei , endemic to the eastern southeastern Brazil and a mountain species present at altitude from 800 to 1200 m, is distinct from the Amazonian and other populations of similar taxa as mentioned above.

The holotype of Eacles guinlei Oiticica Filho, 1941 bear the following data: male, “Terezópolis, no Estado do Rio [= Rio de Janeiro], 900 metros de altitude, capturado por [collected by] Lauro Travassos e José Oiticica Filho [leg.]”, after original description n. 233, Col. Oiticica (MNRJ). The holotype and an undisclosed number of paratypes were destroyed by fire in 2018. To ensure the correct identification and for stabilizing the name of Eacles guinlei , mentioned as a synonym of Eacles masoni fulvaster by Lemaire (1979, 1988) and characterized in detail by Oiticica Filho (1941), a male is herein designated as the neotype ( Figs 10a–b ). The specimen bears the following labels (labels separated by forward slashes): Neotypus, Eacles guinlei ♁, Bonatto & C. Mielke det./ BRASIL: RJ, Teresópolis, 15.I.1985, V.O. Becker col/ Col. Becker 54760/ BC-CGCM/ 10.313 Col. C. Mielke (DZUP).
