Dicromantispa electromexicana
''Dicromantispa electromexicana'' is an extinct species of mantidfly in the neuropteran family Mantispidae known from a fossil found in North America.
==History and classification==
''Dicromantispa electromexicana'' was described from a solitary fossil,〔 which is preserved as an inclusion in a transparent chunk of Mexican amber. At the time of description, the amber specimen was housed in the fossil collection of the American Museum of Natural History in New York City. The holotype fossil is composed of a very complete adult male.〔 Mexican amber is recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. The amber dates from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone, and 26 million years old La Quinta Formation. This age range straddles the boundary between the Late Oligocene and Early Miocene and is complicated by both formations being secondary deposits for the amber, the age range is only the youngest that it might be.
The male holotype was first studied by entomologists Michael Engel of the University of Kansas and David Grimaldi of the American Museum of Natural History with their 2007 type description of the species was published in the natural sciences journal ''American Museum Novitates''. The specific epithet ''electromexicana'' was coined from the Greek word "electron", meaning ''amber'', combined with Mexico as a reference to the nature of the preservation and the country of the type locality.〔 ''D. electromexicana'' is one of two fossil ''Dicromantispa'' species Engel and Grimaldi described in 2007. The other species, ''D. moronei'', is from the similarly aged Dominican amber of Hispaniola.〔
