Dicromantispa electromexicana is an extinct species of mantidfly in the neuropteran family Mantispidae known from a fossil found in North America.

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 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.

Based on the general appearance of the pronotum, D. electromexicana is visually similar to the extant North American Zeugomantispa minuta.

The anal plates of D. electromexicana lack a ventromedian lobe, a feature found in all living members of Dicromantispa.
