Guides
Ephialtini
Ephialtini is a tribe of ichneumonid wasps within the subfamily Pimplinae, comprising approximately 17 genera and at least 120 species. Members are exclusively parasitoids of spiders (Araneae), with many species belonging to the 'Polysphincta group' that attack post-embryonic spiders. These wasps exhibit diverse host specificity patterns, ranging from polyphagy across multiple spider families to strict specialization on particular host species or genera. Some species parasitize adult spiders while others attack spider egg sacs.
Oxyrrhexis carbonator
Oxyrrhexis carbonator is a species of ichneumon wasp in the family Ichneumonidae, first described by Gravenhorst in 1807. It belongs to the Polysphincta genus-group within the subfamily Pimplinae, tribe Ephialtini. The species is a koinobiont parasitoid of spiders, with documented host associations across multiple spider families including Theridiidae and Titanoecidae.
