A new species of hypoderatid deutonymph is described from the subcutaneous adipose tissues of the pelagic cormorant, Phalacrocorax pelagicus Pallas, from Alaska. Neotialges neopelagicus n. sp. is similar to the 3 other Neottialges spp. from cormorants. N. neopelagicus closely resembles N. tasmaniensis Fain & Domrow except the genital apodeme is incomplete in the latter, but the sclerotized T-shaped extremities are connected by a thin line of sclerotization to form a complete central apodeme in N. neopelagicus. There also are minor differences in leg chaetotaxy of these 2 species. The genital apodeme is heavily sclerotized throughout its length in N. evanis Fain and N. pelagicus OConnor. In both these species, seta d4 is long and resembles other middorsal idiosomal setae, whereas it is short and hairlike in N. tasmaniensis and N. neopelagicus. In N. pelagicus terminal seta as on tarsus IV is smooth; it is serrated in the other three species. The single pelagic cormorant we found infected with N. neopelagicus shared this host with N. pelagicus, emphasizing the possibility of coexistence of 2 very similar species of hypoderatids in the same host individual.
从阿拉斯加的海鸬鹚（Phalacrocorax pelagicus Pallas）皮下脂肪组织中描述了一种新的皮蝇科若虫。新种新海鸬鹚虱（Neotialges neopelagicus n. sp.）与来自鸬鹚的其他3种新海鸬鹚虱属物种相似。新海鸬鹚虱与塔斯马尼亚新海鸬鹚虱（N. tasmaniensis Fain & Domrow）非常相似，只是后者的生殖内突不完整，但在新海鸬鹚虱中，硬化的T形末端通过一条薄的硬化线相连，形成一个完整的中央内突。这两个物种在腿部毛序上也存在细微差异。在埃氏新海鸬鹚虱（N. evanis Fain）和海鸬鹚新海鸬鹚虱（N. pelagicus OConnor）中，生殖内突在其整个长度上都高度硬化。在这两个物种中，刚毛d4都很长，与其他中背体躯刚毛相似，而在塔斯马尼亚新海鸬鹚虱和新海鸬鹚虱中，它很短且呈毛发状。在海鸬鹚新海鸬鹚虱中，跗节IV上的末端刚毛是光滑的；在其他三个物种中它是锯齿状的。我们发现感染新海鸬鹚虱的唯一一只海鸬鹚与海鸬鹚新海鸬鹚虱共享这个宿主，这强调了两种非常相似的皮蝇科物种在同一宿主个体中共存的可能性。
