The discarded cow from the flowered desert: revalidation of Gyriosomus crispaticollis Fairmaire, 1886 stat. rev. (Coleoptera: Tenebrionidae) in Southern Atacama, Chile.

Gyriosomus crispaticollis Fairmaire, 1886 is revalidated from the synonymy of Gyriosomus luczotii Guérin-Méneville, 1831 based on the study of G. crispaticollis syntypes and comparative morphological and genetic analyses. Our results suggest that G.

Phylogenomics of darkling beetles (Coleoptera: Tenebrionidae) from the Atacama Desert.

Background: Tenebrionidae (Insecta: Coleoptera) are a conspicuous component of desert fauna worldwide. In these ecosystems, they are significantly responsible for nutrient cycling and show remarkable morphological and physiological adaptations. Nevertheless, Tenebrionidae colonizing individual deserts have repeatedly emerged from different lineages.

Taxonomic and systematic implications of the revision of the phylogenetic relations in the genus Ectinogonia Spinola 1837 (Coleoptera: Buprestidae) of Central Chile.

Ectinogonia Spinola 1837 is composed of 22 species to date, but its taxonomic history has been complex and is still unresolved. The species of the Santiagan Province of Central Chile are particularly complex because they show important morphological variability and overlapping traits, making species identification and delimitation difficult. The main goal of the present study is to show the phylogenetic relationships among species of Ectinogonia of the Santiagan province and discuss the taxonomic and systematic implications of our findings.

A new species of Ogloblin (Hymenoptera, Proctotrupidae, Austroserphinae), a Gondwanic relict from southernmost South America.

is described from southernmost South America. It is a member of the primitive subfamily Austroserphinae (Hymenoptera, Proctotrupidae), which is distributed in Oceania and South America, and is characterized from other species by its relatively larger body size, the presence of long and sword-shaped ovipositor sheaths, M arising very close and distal to 1cu-a, and Cu and m-cu joining at a distance equivalent to the length of 2cu-a. We consider this species to be a Gondwanan relict.

Species delimitation in frogs from South American temperate forests: The case of Eupsophus, a taxonomically complex genus with high phenotypic variation.

One of the most characteristic and abundant amphibian taxa of South American temperate forests is Eupsophus. The ten currently recognized species of the genus have been divided in two species groups, roseus and vertebralis, but most of them, eight, belong to the roseus group. Recent phylogeographic and phylogenetic studies have suggested that species diversity of the roseus group could be underestimated.

Phylogenetic evaluation of taxonomic definition of didelphid mouse opossum of the genus Thylamys from valleys of Coquimbo region, Chile.

Only two species of Didelphidae are currently recognized in Chile, the sister species Thylamys elegans, endemic of Mediterranean ecorregion and Thylamys pallidior, the inhabitant of the Puna and desert canyons. Three subspecies have been described for T. elegans: T.

A new species of Callyntra (Coleoptera: Tenebrionidae) from central Chile.

Callyntra Solier, 1836 is a genus mainly from Chile, with one species occurring in Argentina, which currently contains 20 described species. Recent explorations in the Andes Mountain Range in Chile, have resulted in the collection of specimens morphologically different from all previously described species. The aim of this paper is to describe a new species of Callyntra, discuss its relationship with other species in the genus, and highlight sexual dimorphism and potential conservation status.
