The synanthropic austral-most record of the species Loxosceles hirsuta and the formal record of Loxosceles laeta (Araneae: Sicariidae)

Abstract

A formal record of the medically important species Loxosceles laeta (Nicolet, 1849) and new records of Loxosceles hirsuta Mello-Leitão, 1931 (Araneae: Sicariidae) are provided for La Pampa province, Argentina, comprising its southernmost record. The specimens of L. hirsuta in this work were found inhabiting human structures and were collected in different localities, between long time lapses, which suggests that L. hirsuta much like L. laeta is highly synanthropic and established in La Pampa.
