New Genera and Species of Arrowworms of the Order Phragmophora (Chaetognatha)

New Genera and Species of Arrowworms of the Order Phragmophora (Chaetognatha) The paper continues describing new genera and species of arrowworms from the southwestern Bering Sea and northwestern Pacific (see Kasatkina [2–4]). Diagnoses are presented for two new genera, Protokrohnittella and Protoeukrohnia and six new species of the genus Pseudoeukrohnia (Ps. beringi sp. n., Ps. breviata sp. n., Ps. nesmeyanovi sp. n., Ps. aculeata sp. n., Ps. speciosa sp. n., and Ps. lata sp. n.). Detailed descriptions are presented, provided with drawings and differential diagnoses. The phenomenon of global replacement in the deep-sea and mesopelagial faunas of arrowworms (Chaetognatha) in the western Bering Sea has been confirmed.
