该部落Liparocephalini（Liparocephalus Maklin，1853; Diaulota凯西，1893; Paramblopusa Ahn & Ashe，Amblopusa凯西，1893; Salinamexus摩尔& Legner，1977 [ = Biophytosus摩尔& Legner，1977]），所有这些都仅限于泛北极地区的太平洋沿岸，根据以下联会特征，推测为单系群：颏部无刚毛（在脂头龙属中有一次相反），刚毛仅分布于盔瓣的中部表面和顶端，有刚毛，前颏部有一根中刚毛，中基节腔相邻。讨论了脂头族的自然历史和分类历史。根据幼虫（21个性状，57种状态）、成虫（49个性状，115种状态）和幼虫与成虫结合的性状（70个性状，172种状态），对脂头鱼族的系统发育进行了分析。结合幼虫和成虫数据集的分析与逐次逼近导致在一个单一的最简约的树（长度= 937，CI = 0.885，RT = 0.930）与以下模式的属的关系（外群（Salinamexus + Biophytosus（Amblopusa（Paramblopusa（Diaulota + Genoplectes，Liparocephalus）。
The tribe Liparocephalini (genera Liparocephalus Maklin, 1853; Diaulota Casey, 1893 [ = Genoplectes Sawada, 1955]; Paramblopusa Ahn & Ashe, Amblopusa Casey, 1893; Salinamexus Moore & Legner, 1977 [ = Biophytosus Moore & Legner, 1977]), all of which are exclusively restricted to the Pacific coasts of the Holarctic Region, is hypothesized to be a monophyletic group based on the following synapomorphies: seta v absent (inferred to be lost) from mentum (reversed one time in the Liparocephalus lineage), setae distributed only on mesal surface of galea and apex with setae, one medial seta present on prementum, and contiguous mesocoxal cavities. Natural history and history of the classification of the Liparocephalini are discussed. Phylogenetic analyses of the species of the Liparocephalini are presented based on larval (21 characters, 57 states), adult (49 characters, 115 states), and a combination of larval and adult characters (70 characters, 172 states). Analysis of the combined larval and adult data sets with successive approximation resulted in a single most parsimonious tree (length = 937, CI = 0.885, RT = 0.930) with the following patterns of generic relationships (outgroup (Salinamexus + Biophytosus (Amblopusa (Paramblopusa (Diaulota + Genoplectes, Liparocephalus))))).
