Teschovirus A is currently the sole species in the genus Teschovirus, whose members are divided into 13 subtypes: porcine teschovirus (PTV) 1–13. However, recent discoveries of novel PTV genotypes have suggested that a new species, “Teschovirus B”, should be established. Here, we have identified six of the 19 known genotypes and two novel genotypes (PTV 17–18), revealing the high genetic diversity of the PTV subpopulation in indigenous pigs of western Jiangxi, China. Moreover, we determined the nearly complete genome sequences of PTV 17-SG9 and PTV 18-SG10. Together with PTV 1–13, these novel genotypes were confirmed to be members of the species Teschovirus A based on phylogenetic and genetic divergence analysis. Consequently, the species Teschovirus A now includes at least 15 PTV genotypes.
