Uganda. Also Oriental and Palaearctic regions.


The Eastern Palaearctic species, Brachyzapus nikkoensis (Uchida, 1928), is a parasitoid of two spider species: the barn funnel weaver or domestic house spider, Tegenaria domestica (Clerck, 1757), and the web-weaving spider, Agelena limbata Thorell, 1897 (Agelenidae) (Gauld & Dubois, 2006). The penultimate instar of the ichneumonid  wasp manipulates the host spider to form “veils” of very fine and dense threads covering both the spider and parasitoid larva within the tunnel of the funnel web (Matsumoto, 2008).
