Espèces de rang inférieur
D'après la taxonomie ICTV de 2019, trois espèces sont recensées dans ce sous-genre. Ce sont trois coronavirus de chauve-souris d'Asie ou d'Afrique.
Structure
Les virus de ce sous-genre, comme d'autres coronavirus, ont une enveloppe bicouche lipidique dans laquelle les protéines structurales de membrane (M), d'enveloppe (E) et de pointe (S) sont ancrées[4].

« CoVs are classified into four genera, Alphacoronavirus, Betacoronavirus, Gammacoronavirus and Deltacoronavirus. Within Betacoronavirus, they can be further subclassified into lineages A, B, C and D [1]. In 2018, these four lineages were reclassified as subgenera of Betacoronavirus, and renamed as Embecovirus (previous lineage A), Sarbecovirus (previous lineage B), Merbecovirus (previous lineage C) and Nobecovirus (previous lineage D) [2]. In addition, a fifth subgenus, Hibecovirus, was also included (Figure 1) [2]. »

« The presence of HE genes exclusively in members of Betacoronavirus subgroup A, but not members of Betacoronavirus subgroup B, C and D suggested that the recombination had probably occurred in the ancestor of members of Betacoronavirus subgroup A, after diverging from the ancestor of other subgroups of Betacoronavirus. »
