Nomospheciais a medium-sized genus with six species in the Neotropical region and 13 species in the Oriental and Australian regions. Four species occur in Central America, two of them are also recorded from Mexico.
In Asia, species of the genus are known to parasitize nests of social vespid wasps ( Hymenoptera: Vespidae) of the genera EumenesLatreilleand StenogasterGuérin-Méneville ( Gupta 1962), and some host records are also from lepidopteran families Lasiocampidaeand Lymantriidae. Nothing is known about hosts of the Neotropical species.
