In this work we evaluate the taxonomy of the Lithinini of Austral South America based on a phylogenetic analysis. In our analysis we used outgroup Catophoenissa. Two approaches were used to evaluate phylogenetic relationships: 1) parsimony criterion, and 2) Bayesian inference. Parsimony analysis was conducted in PAUP software, and Bayesian analysis...

... en la genitalia del macho comparte la forma de "W" del gnathos ( Fig. 6a y c) con los géneros Acauro e Incalvertia, se distingue fácilmente de ellos por el proceso del anellus, el cual es membranoso, curvo y cubierto de cerdas dispersas (Fig. 6d). La presencia de un grupo de espinas de similar tamaño se constituye en la autapomorfía para el género. En la hembra la presencia de un corpus bursae esférico o ...

Eupithecia copaquillaensis sp. nov. (Lepidoptera, Geometridae, Larentiinae, Eupitheciini) is described and illustrated. Adults of this new species were discovered using a light trap in the Copaquilla ravine, at about 2800 m elevation on the western slope of the Andes of northern Chile. The morphology of the genitalia of E. copaquillaensis resembles...
Phylogenetic study of the genera of South American Austral Trichopterygini (Lepidoptera: Geometridae, Larentiinae): a new classification. In this work, we evaluate the taxonomy of the Trichopterygini in Chile based on a phylogenetic analysis of the morphological attributes. In our analysis, we used Tatosoma and Sauris as outgroups. Two approaches w...

The systematic position and hierarchical level of the moth taxon Diptychini
Janse (Lepidoptera: Geometridae), the cycad moths, has remained controversial. This
is partly due to their unique morphological and biological characteristics. To study
the systematics, comprehensive molecular analyses of eight genes, in total 6157 bp,
were carried out. We used Bayesian inference to construct phylogenetic trees. The
first analysis (46 Geometridae and 7 non-Geometridae taxa, representing all recently
recognised Geometridae subfamilies) demonstrated that the Diptychini belong to the
Geometridae subfamily Ennominae. The second analysis, focused on the Ennominae
(70 taxa, representing 28 of 30 recently recognised Ennominae tribes worldwide),
found that the Diptychini are nested well within the Ennominae; it is monophyletic
and associated with the complex of southern Hemisphere Nacophorini, refuting
many of the earlier hypotheses about Diptychini relationships. The Diptychini are
considered tentatively valid at the tribe level, but relationships with the Nacophorini
and the Lithinini need further research. The molecular findings were evaluated from
a morphological point of view, which are mostly in agreement with the molecular
results. The Diptychini genera are illustrated and characterised using morphological and
life-history traits. Within the Diptychini, three genera are considered valid. Durbana
Warren (described in 1904) is proposed as a junior synonym of Veniliodes Warren
(described in 1894) (n.syn.). Monotypic Larentioides Prout is combined with the tribe
Lithinini (n.comb.). Homonymy of Diptychini Mirza (described in 1991) (Pisces:
Cyprinidae, Schizothoracinae) with Diptychini Janse (described in 1933) (Lepidoptera:
Geometridae, Ennominae) is noted, the former requiring a replacement name.
A new species of Psilaspilates Butler 1893, P. septentrionalis Parra sp. nov., from the relict coastal forest of Aextoxicon punctatum R. et P. (olivillo) from the Parque Nacional Fray Jorge, Región de Coquimbo, Chile, is described. Previously kwon species of Psilaspilates distribute in the central-south of Chile; therefore, P. septentrionalis sp. nov. is the only species distributed in the northern Chile. Subsequently, the phylogeny of Psilaspilates was inferred using two approximations, maximum parsimony and Bayesian inference. The sister species of the new species, P. concepcionensis y P. stygiana, distribute in central-southern Chile, in coastal forest where olivillo is also present. We suggest that the ancestor of these three species was widely distributed in coastal olivillo forest, and that during the Last Glacial Maximum its populations become isolated and speciation occurs.
