Changes in the architecture of fluvial deposits in the Paganzo Basin (Upper Paleozoic of San Juan province): an example of sea level and climatic controls on the development of coastal fluvial…
Paganzo Group exposures (Tupe Formation) in the Huaco area provide an excellent opportunity for assessing the role of sea level and climatic changes on the morphology and nature of coastal fluvial…

Valley downcutting and tectonically-related landslides have driven the evolution of the landscape in the transitional zone between the Central and Patagonian Andes. Since the onset of the basin's…
Sedimentation model of piggyback basins: Cenozoic examples of San Juan Precordillera, Argentina
Abstract Piggyback basins are one of the most important sediment storage systems for foredeep basins within foreland basin systems, so understanding the dynamics of sediment accumulation and…
Phylogeny and revision of Toechorychus Townes (Hymenoptera, Ichneumonidae, Cryptinae), with descriptions of thirty-five new species.
The Neotropical Toechorychus Townes is revised, cladistically defined, and diagnosed; a total of 40 species are recognized, 35 of which are described as new, and seventy new characters are proposed for the analysis of Cryptinae phylogeny.
Trigonalidae (Hymenoptera) from cacao agroforestry systems in northeastern Brazil, with two new species of Trigonalys Westwood
A survey of Trigonalidae from cacao agroforestry systems in southern Bahia, northeastern Brazil, is conducted, and three species are recognized and two new species are described and illustrated.
Phylogenetic revision and the origin of Polyphrix Townes (Hymenoptera, Ichneumonidae, Cryptinae), with description of a new species
All analyses recovered all known Polyphrix species as a monophyletic group and an Amazonian origin of the genus, with species from northern Brazil appearing basally in the clade, while both Atlantic Forest species appear as sister groups.
Cladistic assessment and description of a new Neotropical genus and species of Lymeonina (Hymenoptera, Ichneumonidae, Cryptinae)
The Cryptini Petila new genus is proposed, described, illustrated, and cladistically compared with representative species of ten genera of the subtribe Lymeonina and six outgroup species, suggesting that Petila must indeed be treated as a distinct genus.
Revision and phylogeny of the rare Priotomis Townes (Hymenoptera, Ichneumonidae, Cryptinae), with three new species and first description of the male
The monophyly of the genus and the relationships of its species were cladistically tested using implied weighting, in a matrix with 22 species, including four species of Priotomis, and 92 external structural characters, and all analyses recoveredPriotomis as monophyletic.
