Parastemmiulus elektron 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 Instituto Nacional de Antropología e Historia in San Cristóbal de las Casas, Simojovel. The holotype fossil is composed of a very complete adult female recovered from the La Guadalupe Quarry.^[1] Mexican amber is recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. The amber dates from between 23 million years old at the oldest and 15 million years at the youngest. The La Guadalupe Quarry site is an outcrop of amber bearing strata belonging to the Mazantic shale. The deposits preserve a transitional river or stream environments near the coast and preserves fossils of a mangrove forest ecosystem.^[1][2][3]

The holotype was first studied by a team of researchers headed by Francisco Riquelme of the Universidad Autónoma del Estado de Morelos with their 2013 type description of the genus and species being published in the natural sciences journal Historical Biology. The genus name is a combination of the genus Stemmiulus and "para" meaning along side, a reference to the similarities between the two genera. The specific epithet elektron was is based from the Greek word meaning amber.^[1]
