Zatypota is a cosmopolitan genus with about 50 species. Twelve species occur in the Nearctic region, ten species in Central America, and one species was recently described from Cuba. Four species of Zatypota were found to occur in Mexico.
Zatypota patellata Townes was recorded from Mexico on base of one poorly preserved female (Ruíz-Cancino et al. 2002: 645; Hernández-Aguilar et al. 2005: 470). This specimen has a distinct hairless groove on inner side of the hind tibia, and undoubtedly is a member of the genus Flacopimpla (see Remarks under F. kasparyani). Thus, Z. patellata is excluded from the Mexican fauna.
Species of Zatypota are koinobiont ectoparasitoids of adult spiders, mainly the family Theridiidae. The larva of the parasitoid induces its host spider to build a modified web providing apparent protection and support of the wasp’s cocoon (Eberhard 2010). However, Kloss et al. (2024) observed Z. alborhombarta and its host spider Cryptachaea migrans and found that modified webs built by parasitized spiders in the host web did not improve the survival of parasitoid pupae, and they suggested that the effects of altered web designs may depend on specific host-created web features and environmental factors like predation pressure (Kloss et al. 2024).
Zatypota lagiralda Gauld et al. is included to the key because it was described from El Salvador, and therefore has the potential to be found in Mexico.
