The genus Meligethinus Grouvelle, 1906 represents a small group of pollen beetles, including some twenty species
distributed from southern Palaearctic areas to northern Oriental and Afrotropical regions. All constituent species appear to
be strictly associated as larvae and adults to male inflorescences of palms (Monocots: Arecaceae). Two new species of this
genus (Meligethinus mondlanei sp. nov. and M. hamerlae sp. nov.) were recently discovered in southern Mozambique,

The genus Stylogaster Macquart (Diptera: Conopidae) is sister to the remainder of the Conopidae. While all other Conopidae are endoparasitoids of aculeate Hymenoptera, species of Stylogaster appear to be endoparasitoids of ‘orthopteroids’, as the only confirmed rearing records are from crickets and cockroaches. Many calyptrate flies have been observed with Stylogaster eggs attached, but since no Stylogaster have been reared from any dipterans, it is still unknown if these flies are hosts, results of accidental oviposition or carry the eggs to the actual hosts.
