Ganime. Host: Lycosa erythrognatha Lucas ( Lycosidae ), adult or subadult female. The wasp grasped the immobilized wolf spider by the base of its left pedipalp with her mandibles and pulled it backwards, dorsal side upward, across stones and large rocks. She interrupted prey transport to move into grasses to groom herself before resuming transport of the spider ( Ganime 2022 ). This is the first host record and new host family, genus, and species for Arachnospila trochilinus , if it is that species. The host spider is the same as for A. imitatrix , Lycosa erythrognatha , reported simply as? Lycosa sp. ( Kurczewski et al. 2020 ). In that paper, the wasp captor was erroneously reported as Anoplius ( Arachnophroctonus ) sobrinus (Spinola) .
