  A further new species for the genus Ananteris Thorell, 1891 (Scorpiones: Ananteridae) from a poorly prospected region of Brazilian Amazonia Abstract  A new species of the genus Ananteris Thorell, 1891 is described from the region which today defines the ‘Reserva Biológica do Río Trombetas’ in the state of Pará, Brazil. The collection of the unique specimen, presently study, took place previously to the definition of this reserve, in a joint field trip with a team of the Instituto Brasileiro de Desenvolvimento Florestal (IBDF). Ananteris antoni sp. n. is described based on one female specimen collected in a zone of dense humid forest, under death log. With this new description, the number of Ananteris species known for the scorpion fauna of Brazil is now raised to 33. Lourenço W.

Synanthropic species of spiders – those that live in associationwith or benefit from humans and their environments – mayhunt various types of arthropods inside houses (Uhlenhaut, 2001).Among other taxa, numerous species of synantrhopic spiders preyon other spiders. This feeding behaviour is particularly common in spiders of the genus Pholcus Walckenaer, 1805, which havebeen observed preying on a variety of araneomorph spider taxa (Uhlenhaut, 2001; Sherwood, 2019). In Poland, the genus Pholcus is represented by three species (Nentwig et al., 2024).
