The type species, J. hirtus, was transferred to this genus in 1980; it was formerly known as Piptoporus hirtus.Thorn RG. (1980). "Some polypores misclassified in Piptoporus".

The genus name of Jahnoporus is in honour of Hermann Jahn (1911 - 1987) German teacher, Ornithologist and Botanist (Mycology).
The genus was circumscribed by Ingo Nuss in Hoppea vol.39 on page 176 in 1980.
