Definition and diagnosis. Several specimens from Ecuador identified as Milanion alaricus (Plötz, 1884) (type locality in Brazil: Bahia) were not closely related to the syntype of M. alaricus ( Fig. 2) and formed a clade distinct from all other species of the genus. Therefore, they represent a new species. This new species keys (incompletely) to M. alaricus (E.46.6) in Evans (1953) and differs from its relatives by a vestigial (or lacking) white spot in forewing cell CuA 2 -1A+2A, spot at the base of cell M 3 -CuA 1 is larger, more triangular than rounded (as in M. alaricus ) with its distal part protruding distad of the spot in the cell CuA 1 -CuA 2, ventral hindwing area by costa in basal two-thirds is not white, but is pale-brown, not the same dark color as the brown marginal wide border. This species is not cryptic and is diagnosed reliably by phenotype. In DNA, a combination of the following base pairs is diagnostic in the nuclear genome: aly1313.22.1:G201A, aly923.23.1:T1497C, aly15192.3.7:G100A, aly 1405.11.14:C72T, aly 2095.5.1:C135T, and COI barcode: T133A, T301C, A577G, A592G, A628T.

Type locality. Ecuador: Napo Province, Jatun Sacha Biological Reserve, elevation 450 m, GPS −1.0667, −77.6167.

Etymology. The name alaricus is derived from Alarīks (king of all) with the prefix “alla-” (all, everybody, entire) suggests a kingly, royal, or noble identity. Laricus (i.e., not alaricus ) is a noun in apposition and a shorter name for this more northern species.

Distribution. Known only from northeastern Ecuador.
