Anoplius (Notiochares) triquetrus (Fox)

BRAZIL: Minas Gerais State, Diamantina; 22 July 2023, 1353 PM; A. Ferreira Righi. Host: Pavocosa sp. ( Lycosidae ), adult or subadult male. The wasp grasped the third left coxa of the immobilized wolf spider with her mandibles and dragged in across bare ground, retaining the spider in a perpendicular position relative to the wasp’s body position ( Fig. 16 ; Ferreira Righi 2023).

This is the second host record and new host family, genus, and species for Anoplius triquetrus . The first observation of A. triquetrus implicated the host spider as being an unidentified species of Pisauridae (fishing spider) ( Rapoza et al. 2019). Lycosidae and Pisauridae are both families in the superfamily Lycosoidea .
