Brasixenos mikati Benda & Straka sp. nov., a new species of Strepsiptera of the genus Brasixenos Kogan & Oliveira, 1966 (Xenidae) from southern Guatemala, is described based on the female cephalothorax, male cephalotheca and the first instar larvae. It represents the first species described from the swarm-founding wasp of the genus Agelaia Lepeletier, 1836 (Hymenoptera: Vespidae: Epiponini). A total of 164 individuals of Agelaia myrmecophila (Ducke, 1905) were collected during flying out from a single nest. Of the total number of emerging wasps, 13% (21 individuals) were parasitised. Diagnoses and descriptions of the female cephalothorax, male cephalotheca, and the first instar larvae are presented, and identification based on external morphology is discussed.
