•A new splipalmivirus (CnSpV1) with divided RdRP was isolated from C. naterciae.•CnSpV1 has four (+)RNA genomic segments RNA1 to RNA4.•RNA1 and RNA2 encode divided RdRP motifs F, A and B, and C and D, respectively.•Protoplast fusion assay suggests an extremely narrow host range of CnSpV1. Positive-s...
