Ismaridae is a family of insects belonging to the order Hymenoptera. About 50 species are known in this small relictual group; all the species for which the biology is known appear to be hyperparasitoids that parasitize Dryinidae (that attack leafhoppers).
This lineage was formerly included in the family Diapriidae, as the subfamily Ismarinae, but differ from diapriid wasps by lacking a facial projection from which the antenna arise, and characterized by various degrees of fusion of the metasomal terga. The family historically included only two genera, Ismarus and Szelenyioprioides,[1] though the latter genus was recently synonymized with the diapriid genus Spilomicrus,[2] thereby restricting the family to solely Ismarus.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
