D i s t r i b u t i o n: Known from all zoogeographical regions. In the Malagasy subregion recorded from Seychelles (Inner Seychelles, Coetivy), Madagascar, Réunion, Mauritius and Rodrigues.

The cosmopolitan species Evania appendigaster is an important control agent of the American cockroach, Periplaneta americana (LINNAEUS 1758), which is a nasty household pest in tropical and subtropical areas. Other hosts in the Mascarene islands could be Periplaneta australasiae (FABRICIUS 1775) and Rhyparobia maderae (FABRICIUS 1781). MOUTIA & MAMET (1947) erroneously recorded spiders as hosts.
