The monotypic genus Mymarilla Westwood is known only from St. Helena, a remote island in the South Atlantic Ocean. The peculiar species M. wollastoni Westwood (Mymaridae) is redescribed and illustrated from non-type material. Mymarilla is compared with Cremnomymar Ogloblin spp. from the Juan Fernández Islands in the South Pacific Ocean. Stephanodes Enock is shown to be the most likely sister genus to Mymarilla. Nesopolynema Ogloblin, syn. n., Oncomymar Ogloblin, syn. n., Scolopsopteron Ogloblin, syn.n., are placed in synonymy under Cremnomymar and their species transferred as Cremnomymar caudatum (Ogloblin 1952), comb. n., C. dipteron (Ogloblin 1957), comb. n., and C. kuscheli (Ogloblin 1952), comb. n. Wing shape and wing reductions in Mymaridae are discussed in relation to biogeography, particularly with respect island faunas and to four genera, Cremnomymar, Mymarilla, Parapolynema Fidalgo, and Richteria Girault, some or all of whose species have more or less convex fore wings.

Plain Language Summary

The purpose of this paper is to redescribe an unusual genus and species of parasitic wasp and compare it with another genus and species described previously from the Juan Fernandez Islands. Several synonyms are proposed for the second genus, thus clarifying their relationships. Wing modification in Mymaridae is discussed and some unusual types are illustrated. The scientific impact is to add scientific knowledge about a group of parasitic wasps whose members are abundant worldwide but are generally poorly studied because of their small size. They are all parasites in the eggs of other insects. Some species have been used successfully in biological control programmes against pests in forestry and agriculture.
