The genus Amauropelta is very similar morphologically to the other two genera of the amaropeltoid clade: Coryphopteris and Metathelypteris, differing of the first basically by the lack of sessile, resinous, reddish glands on the lamina between veins (except in the A. resinifera group) and of the second by the veins running to the margins.

Within the Thelypteridaceae on the Neotropics region is quite easy morphologically recognisable by the pairs of gradually reduced proximal pinnae, that vary between to few to many, depends on the species case and the veins is usually prominent abaxially and adaxially, lowermost pair from adjacent segments running to margin just above sinus between adjacent lobes, rarely running to sinus (A. linkiana), never united to form excurrent veins that run to sinuses, veins ending at pinna margins.

are similar to the more distantly related to the Pseudocyclosorus, which also has free veins, and many pairs of gradually reduced proximal pinnae.

Sm Amauropelta subgenera Parathelypteris is composed of six species (listed below) and could be distinguished from others (Parathelypteris, Nibaa and Venus) by proximal pinnae typically abruptly- or little reduced and by the biogeographical distribution (East Asia), x= 27,31.

Sm Amauropelta subgenera Venus is composed of two species (listed bellow) x= 31.
