Diagnosis. The moths of the genus Maikona Matsumura, 1928 exhibit male genitalia that are very similar to those of the genus Alloasteropetes Kishida & Machijima, 1994, but they differ significantly in their wing patterns. Maikona moths follow the typical trifid noctuid moth pattern, with orbicular and reniform stigmata and distinct antemedial and postmedial transverse lines (Owada et al. 2003a). Adult Maikona moths are notable for their very hairy bodies, a prominent crest on the first abdominal segment, and blackish body and wing coloration (Owada et al. 2003b). In the male genitalia of Maikona, the ventral projection of the valva is connected to a sclerotized plate that originates from a basal sclerotized part of the costa. In contrast, in Alloasteropetes, a sclerotized plate from the costa is present, but the ventral projection of the valva is absent (Owada et al. 2003b).
