Subfamily: Actantavirinae

Family: Hantaviridae

Subfamily: Actantavirinae

Distinguishing features

Acantavirins infect actinopterygian fish (Shi et al., 2018, Costa et al., 2021, Hierweger et al., 2021, Costa et al., 2023).

Genus demarcation criteria

Demarcation of genera is based upon DivErsity pArtitioning by hieRarchical Clustering (DEmARC) analysis) using concatenated deduced S, M, and L segment expression product sequences (Laenen et al., 2019). DEmARC analysis gave a frequency distribution of Pairwise Evolutionary Distance (PED) values of which the threshold of 0.95 gave an optimal clustering cost of zero and is used as the hantavirid genus demarcation criterium.
