The entire species complex shares one glacial
refugium, in the periglacial region |
Two species retreated to different
periglacial refugia |
Nebria riversi, N. ingens, and the
intermediate morphotype retreated to three different periglacial refugia |

The
glacial refugia were within drainage basins: Tuolumne + Merced, San
Joaquin, King, and Kern + Kaweah |
