De las 118 familias de arañas conocidas, la familia Salticidae es la que presenta mayor riqueza específica con un total de 636 géneros y 6089 especies descriptas (World Spider Catalog, 2018). A pesar de ello, sólo diez especies fueron citadas en el último catálogo de arañas de Uruguay (Capocasale & Pereira, 2003). Por tal motivo se considera que la...

In previous studies, Uruguay has been considered a biogeographical crossroads. Paso Centurión and Sierra de Ríos in eastern Uruguay were recently entered into the National System of Protected Areas. The landscape is characterized by a mosaic of different ecosystems located in one of the dendrofloristic hotspots proposed for the country. The spiders...

Jumping spiders present natural enemies like insects of the subfamily Mantispinae. We report for the first time for Uruguay the salticids Neonella minuta, Tullgrenella serrana and the presence of Mantispinae larvae in this species and in Sarinda sp. In T. serrana we record the development of the parasitoid Dicromantispa gracilis.

Sarinda marcosi Piza, 1937 is an ant-like jumping spider that shares its microhabitat with the carpenter ant Camponotus mus Roger, 1863 (Hymenoptera: Formicidae). The objectives of this study were to record S. marcosi from Uruguay, to describe the type of mimicry present in this species, and to determine the ant model it mimics and how closely it r...

We present the first record of Gypogyna forceps Simon, 1900 from Uruguay. This also constitutes the first record of tribe Scopocirini from the country, as well as being the southernmost record for the tribe and species. We provide new data and comments on its taxonomy, including the first description and images of internal female genitalia, as well...

Huriini Simon, 1901 currently consists of six genera and 17 species, distributed exclusively in South America. In this work, the huriine genus Guriurius Marta, Bustamante, Ruiz & Rodrigues, gen. nov. is proposed with two new species herein described: Guriurius minuano Marta, Bustamante, Ruiz & Rodrigues, sp. nov. (type species) and Guriurius nancya...

Female Gypogyna forceps walking and waving the first leg pair.

The genus Mastophora Holmberg, 1876 is represented by 50 species that are distributed mainly in America and the Antilles. Males are much smaller than females and are not described in more than half of the known species of the genus. The high specificity of their diet (moths) and the technique which females use to capture their prey have been record...

The male of the wolf spider Paratrochosina amica Mello-Leitão (1941) is redescribed, and the female of this species is described for the first time. Additionally, we evaluate the phylogenetic position of P. amica using the mitochondrial genes cytochrome c oxidase subunit I (cox1), the 12S rRNA (12S) and 16S rRNA (16S), NADH deshydrogenase subunit I...

La mirmecomorfia es un tipo de mimetismo en el cual algunos organismos imitan ciertas especies de hormigas, tanto en morfología, comportamiento y coloración. En la familia Salticidae, varios géneros presentan este tipo de mimetismo que les otorga ventajas para obtener su alimento y evitar la depredación. El objetivo de este estudio fue reportar la...
