Lectotype hereby designated , male [ BRAZIL ], Rio Grande do Sul, with three labels: two printed labels “Stieglmayr, Rio Gr. Do Sul” and “ Ende August”, and one handwritten label in red ink “ Eucereon sericeum Zerny ♂ type ”. Five paralectotypes , three males and two females, with the following labels: first male with exactly the same labels as the lectotype ; second male with identical labels, except for the second, which is “Anf. Jänner”; third male with two handwritten labels, “Semper Nea Friburg [Nova Friburgo] 1873” and the type label; first female with three labels: two printed labels “Stieglmayr, Rio Gr. do Sul” and “Mitte Septb.”, plus the type label; second female also bearing three labels, “Stieglmayr, Rio Gr. do Sul”, “Jänner”, and the type label. Current combination. Eucereon sericeum Zerny, 1931 . Condition of the types . Lectotype . Left forewing slightly torn, both forewings somewhat worn. Paralectotypes . Male from the end of August with dirt on the wings and antennae. Male from Nova Friburgo with dirt on the wings and antennae and missing the abdomen. Male from January missing the head and most legs. Females in very good condition. Remarks. This species was described from six specimens, four males and two females, all deposited at the NHMW. Eucereon sericeum is certainly not part of a monophyletic concept of Eucereon , and it is likely that it does not even belong in Ctenuchina . It seems to be closely related to three other species, E. album ( Druce, 1894 ) , E. vestalis ( Schaus, 1892 ) , and Hyaleucerea mundula ( Berg, 1882 ) .
