A new species of Chelodesmidae is described from northern Uruguay, Sandalodesmus joachimadisi n. sp. The new species differs from other congeners by particular features of the gonopods. Sandalodesmus joachimadisi n. sp. belongs to the iguazuensis species group. Photographs of the new species, data on its natural history and a geographic distributio...

Anelosimus jabaquara (Theridiidae) is a social spider that lives in communal nests using tree leaves as retreats and it is known only from Brazil. There have been no studies that address sexual aspects in this species. This paper describes the sperm induction of this species under laboratory conditions. Out of a total of 20 males, we observed eight...

The millipede species Oxidus gracilis (Polydesmida: Paradoxosomatidae) is recorded for the first time in Uruguay. This constitutes the first record of the Order Polydesmida and the family Paradoxosomatidae for the country. The species was found in synantropic environments. Data on its natural history and distribution in the country are included.

The educational and research experience was carried out in the context of confinement with six people deprived of liberty and a monitor in the territory. Spiders were sampled in three sites of the Penitentiary Institution: rooms of Persons Deprived of Liberty, wild vegetation field and organic crops. The hypothesis was that diversity would be influ...

Detailed descriptions of sperm induction are rare in the literature. Anelosimus vierae Agnarsson, 2012 (Theridiidae) is a Uruguayan subsocial spider that lives in communal nests. This paper describes the sperm induction of this species under laboratory conditions. We collected spiders in Montevideo, Uruguay, from different trees and placed them in...

This paper aims to review the studies on the reproductive behaviour of the endemic Uruguayan subsocial spider Anelosimus vierae. We framed the reproductive behaviour of this species referring to the most important aspects of his life history. We show the sperm induction behaviour performed necessarily by males to transfer sperm from their genitalia...

Eight legs are worth more than a thousand words: arachnids in the publicity. This work represents the synthesis of an investigation about the use of arachnids in advertisements and advertising campaigns. We conducted an exhaustive search of several websites and analyzed the main image used, the purpose of the advertising, and the relationship betwe...

Summary Food exchange by the mother to her brood is a frequent phenomenon in social arthropods. In the subsocial spiders of the genus Anelosimus Simon, 1891, maternal regurgitation to offspring plays an important role in the survival of the colony. Regurgitations also occur between subadult males and females in Anelosimus vierae Agnarsson, 2012. In...
