Unveiling high solifuge diversity: Review of the genus Pseudocleobis Pocock, 1900 (Ammotrechidae) in Chile with the description of nine new species.

The Pseudocleobis from Chile are revised. Pseudocleobis morsicans (Gervais, 1849) and P. chilensis Roewer, 1934 are considered species inquerenda.

Genetic barcodes for species identification and phylogenetic estimation in ghost spiders (Araneae: Anyphaenidae: Amaurobioidinae).

The identification of spider species presents many challenges, since in most cases the characters used are from genital structures that are only fully developed in the adult stage, hence the identification of immatures is most often not possible. Additionally, these structures usually also present some intra-specific variability, which in some cases makes the identification of closely related species difficult. The genetic barcode technique (DNA barcodes), based on sequencing of the mitochondrial marker cytochrome c oxidase subunit I (COI ), has proven a useful, complementary tool to overcome these limitations.

Natural History of the Genus Saussure, 1888 (Orthoptera: Tristiridae), an Endemic and Eremic Element of the Transitional Coastal Desert of Chile.

The genus belongs to the family Tristiridae, an orthopteran group that is distributed across the transitional region of South America and represented in the Andean areas of Peru, Argentina, and Chile. The species of have morphological adaptations that make them especially suited for surviving in extreme arid environments and are an endemic and eremic group of the north-central region of Chile. On the basis of field samplings, direct observations, and a comprehensive literature review, we collected information about the genus .

The tiniest violin: the male of (Araneae, Sicariidae).

In recent years, several endemic species of , violin spiders, have been described from the North-Central Chile biodiversity hotspot, some of which have ambiguous placement within the species groups of the genus. In a recent expedition to the Atacama region, we collected male specimens representing new records of two recently described species: Taucare-Ríos, Brescovit & Villablanca, 2022 and Brescovit, Taucare-Ríos, Magalhaes & Santos, 2017 (Araneae, Sicariidae). Males of the latter are hitherto unknown and are here described for the first time.

A new species of the genus Osornolobus Forster & Platnick from the maulino forests of Chile (Araneae, Orsolobidae).

A faunistic survey in the Maule region in central-southern Chile resulted in the discovery and description of a new species of the spider genus Osornolobus: O. violetaparra n. sp.
