[1] This species was discovered by Spanish zoologist Marcos Jiménez de la Espada in November 1864.

Espada encountered four females in Babahoyo, Ecuador near the Guayas River in the crack of an old tree, roosting with harmless serotine bats.

[2] Its species name aequatorianus is derived from the Latin word aequatoriensis, meaning "Ecuadorian."

[3] This species is found in dry, tropical forests in west central Ecuador.

They are listed as endangered because they occur at fewer than five locations, and a decline is projected in their area and quality of habitat.
