Abstract:

We recorded changes in the deep-sea marine arrowworm (Chaetognatha) fauna in the early 1990s in the western Bering Sea and northwestern Pacific: the absence of previously common species from the order Phragmophora and the appearance of representatives of new genera and species of the same order. We present diagnoses of five new species of the genus Pseudeukrohniawith detailed descriptions and figures and also a differential diagnosis for all known species of this genus, including those described in 1997.
