Genus Eucheila Dejean, 1829

Eucheila Dejean [in Dejean and Boisduval], 1829: 60 (as Eucheyla ). Type species: Eucheyla flavilabris Dejean, 1829 by monotypy. Etymology (original). From the Greek eu (well, large) and cheilos (lip), alluding to the large size of the labrum (" lèvre supérieure très-grande ") of the adult [feminine]. Note. Eucheila is an incorrect subsequent spelling of Eucheyla Dejean, 1829 introduced by Dejean (1831: 455). The spelling Eucheila is in prevailing usage and attributed to the original publication by recent authors (e.g., Lorenz 2005: 463; Anichtchenko 2010: 189); therefore, it is deemed to be the correct original spelling (ICZN 1999: Article 33.3.1).

Euchila Agassiz, 1846: 146 [junior homonym of Euchila Billberg, 1820]. Unjustified emendation of Eucheila Dejean, 1829.
