摘要:"The six genera of Lithinini from North America have been studied and described previously, but practically nothing is known about the members of this tribe from the remainder of the New World. Moths from Chile and adjacent Argentina have been studied for this group, and a number of genera are defined. The following genera and their type species (all described as new) are proposed: Yalpa (Y. dalcahue), Callemo (C. monotonos), Guara (G. rhaphis), Siopla (S. derance), Nucara (N. recurva), Acauro (A. rotundus), Calta (C. lamella), Yapoma (Y. chone), Duraglia (D. xanthe), and Laneco (L. suffuscus). The following generic changes are proposed: Proteopharmacis Warren, 1895, is placed as a junior subjective synonym of Odontothera Butler, 1882; Catrielia Orfila and Schajovskoy, '1959' (1960), is placed as a junior subjective synonym of Euclidiodes Butler, 1895; Incalvertia, replacement name and new status is proposed for Calvertia Warren, 1908, not Bourguignat, 1880. On the specific level, Lacaria monrosi Orfila and Schajovskoy, 1959, is placed as a synonym of L. schajovskoyi (Sperry, 1954); as this leaves the former species that was incorrectly identified without a name, Lacaria orfilai, new species, is proposed for this taxon. Orfila and Schajovskoy, 1959, published the new tribal name Lacarini. After studying the group, I place the name Lacarini as a junior subjective synonym of Lithinini. All the genera included in this paper have some of their diagnostic characters listed in several tables, are fully described, and are separable by using the keys to the adults based on external morphology and male genitalia. Illustrations for adults and genitalia of all the genera are included. The difficulty with defining the Lithinini as a monophyletic group, based on shared apomorphic characters of the adults, is discussed. It is suggested that a careful analysis of the eggs, larvae, and pupae will have to be undertaken before any definitive characterization of the group can be obtained"--P. [1].
