Type species: Sphex appendigaster Linnaeus, 1758 .

See Deans (2005: 24) for complete taxonomic information.

This is the type genus of the family with numerous species mainly distributed in tropical areas. The genus need to be revised because some of described species may be synonyms of the cosmopolitan Evania appendigaster or some Evania species will be later transferred into other genera. Parasitoids of cockroach oothecae mainly of the genus Periplaneta Burmeister, 1838 (Blattidae) .

The following six species of this genus are known in the Palaearctic region (predominantly in it south part): Evania appendigaster (Linnaeus, 1758) (nearly cosmopolitan but largely restricted to urban environments, in Europe from Greece to Sweden); E. carinigera Kieffer, 1905 (Morocco); E. cribrata Semenow, 1892 (Armenia, Azerbai- jan, Georgia, Iran); E. dimidiata Spinola, 1838 (Azerbaijan, Egypt, Ethiopia, Israel, Libya, Sudan, Syria, * Russia, Turkmenistan); E. hunteri Mani, 1943 (Afghanistan, Pakistan); E. nigrata Gmelin, 1790 (“Europe”); E. stenochela Kieffer, 1911 (Pakistan) (Deans, 2005, 2008).

Number of species: World—about 70, Palaearctic—6, Russia—1. Discovery of cosmopolitan E. appendigaster in the Russian fauna is also very likely.
