It is named in honor of Luis G. Pagano, Argentinean ornithologist who helped to collect this species.

It is found in Argentina, in the Salta province, next to the south Bolivia border.

[1] Plesiopelma paganoi differs from most of the Plesiopelma genus, except from P. insulare, by the high number of labial and maxillary cuspules and absence of spiniform hairs on the retrolateral face of cymbium.

[1] Plesiopelma paganoi was found only in the Yungas eco-region in high cloud forest areas.

A juvenile was found at the piedmont jungle in the tiny crevices underneath decomposing logs a microhabitat shared with specimens of a species of Acanthoscurria.
