  New records and invasion risk of Stenochrus portoricensis Chamberlin, 1922 (Schizomida: Hubbardiidae) in Brazil Abstract Stenochrus portoricensis Chamberlin, 1922 is a schizomid native to the Caribbean and Central America and is notable for facultative parthenogenesis and a broad synanthropic distribution. It is widely reported as an exotic species in several regions worldwide, with recognized invasive potential. Here, we expand its known distribution in Brazil by documenting the first records from the state of Mato Grosso and new occurrences in tourist caves in Bahia. We also model the species’ potential distribution in South America using the Maximum Entropy (MaxEnt) algorithm under current and future climate scenarios. The models indicate higher habitat suitability in regions characterized by low annual temperature variation and consistent rainfall patterns, conditions typical of tropical and subterranean environments, and predict range expansion under future climate change, p...

Mangora acalypha (Walckenaer, 1802), araña europea 2026 (Arachnida: Araneae)


Abstract

Mangora acalypha (Walckenaer, 1802) has been chosen by specialists from several European countries as the spider of the year for 2026. It is the only species of the genus Mangora found on the European continent. Thanks to the characteristic color pattern on the dorsal side of the opisthosoma, even juvenile stages can be easily identified. The Iberian Peninsula has abundant records distributed throughout its territory, and therefore the species is not considered threatened.
