Priocnessus sericeus Dreisbach

COLOMBIA: Cundinamarca Department, Tena; 13 December 2020, 1551; J. N. Rozo Pinilla. Host: Ctenus sp. (Ctenidae) , adult or subadult female. The wasp straddled the immobilized wandering spider, dorsal side upward, and grasped the patella of its left foreleg with her mandibles. She then walked to the front of the spider, grasped its chelicera with her mandibles, and turned it onto its back, ventral side upward. Maintaining this grasp of the spider, she walked forward into dense vegetation, occasionally pausing and walking backwards for a short distance before turning around and walking forward ( Fig. 5 ; Rozo Pinilla 2020).
