Eomeropidae is a family of aberrant, flattened scorpionflies represented today by only a single living species, Notiothauma reedi, known from the Nothofagus forests in southern Chile, while all other recognized genera in the family are known only as fossils, with the earliest definitive fossil known from Liassic-aged strata,[1][2] and the youngest from Paleogene-aged strata.

[1][3] Notiothauma adults are thought to be saprophagous with a preference for carrion, having been observed feeding on dead chickens and rabbits, though in one experimental study they were also observed feeding on plant material.

[4] There are six extinct genera and one monotypic living genus which have been placed in Eomeropidae.

The proposed phylogenetic relationships within Eomeropidae based on Soszyńska-Maj et al 2016.

[6] Jurachorista Jurathauma Eomerope Tsuschingothauma Notiothauma Typhothauma Eomeropids have been suggested to be most closely related to the also poorly diverse and relictual Meropeidae.
