根据形态数据，在东北太平洋，包括白令海和邻近的北冰洋(波弗特海)，共识别出9个本地种。其中四个已被描述：Philine ornatisima Yokyama，1927，Philine bakeri Dall，1919，Philine Polystrigma(Dall，1908)和Philine hemphilli Dall，1919。其中5个为新种，在此描述：Philine mlean i sp.新种Philine Baxteri sp.Nov.，Philine maraquiasi sp.Nov.，Philine wareni sp.Nov.和Philine harrisae sp.11月这些物种在内部和外部形态特征上表现出很大程度的差异(即有或没有肌板，不同的神经节结构和牙齿形态，不同的生殖解剖学特征)，它们很可能属于不同的支系(属)。然而，由于菲林没有一个全面的系统发展史，他们在这里暂时被认为是菲林感觉拉托。除9个本地种外，2个引进种：Philine orientalis A.Adams，1854和Philine auriformis Suter，1909在这里图解并与本地种进行比较，以便于识别。最后，根据形态数据，对两个以前被认为是飞蝇科成员的种进行了解剖检查，并确认它们是老蝇科的成员，即Laona calfornica(Willett，1944)和Philinorbi ae，Philinorbis Albus(Mattox，1958)。
Based on morphological data a total of nine native species of Philinidae are recognized from the northeastern Pacific including the Bering Sea and the adjacent Arctic Ocean (Beaufort Sea). Four of them have been previously described: Philine ornatissima Yokoyama, 1927, Philine bakeri Dall, 1919, Philine polystrigma (Dall, 1908), and Philine hemphilli Dall, 1919. Five of them are new and described herein: Philine mcleani sp. nov., Philine baxteri sp. nov., Philine malaquiasi sp. nov., Philine wareni sp. nov., and Philine harrisae sp. nov. These species display a substantial degree of variation in internal and external morphological traits (i.e., presence/absence of gizzard plates, different radular structure and tooth morphology, various reproductive anatomical features) and it is likely that they belong to different clades (genera). However, in the absence of a comprehensive phylogeny for Philine, they are here provisionally regarded as Philine sensu lato. In addition to the nine native species, two introduced species: Philine orientalis A. Adams, 1854 and Philine auriformis Suter, 1909 are here illustrated and compared to the native species to facilitate identification. Finally, two species previously considered members of Philinidae are examined anatomically and confirmed as members of Laonidae, Laona californica (Willett, 1944) and Philinorbidae, Philinorbis albus (Mattox, 1958), based on morphological data.
