Abstract

The first Laurentian records of Pacificurus Ramsköld, 1986 are provided by Pacificus chilorhodus n. sp. (latest Llandovery?–early Wenlock, Mackenzie Mountains, Canada) and Pacificurus sp. A (early Ludlow, northern Maine). These closely related species represent an early divergence (minimally late Llandovery) from Australian/Asian congenerics.
