Pilum pilum gen. et sp. n. is described from the warmouth, Lepomis gulosus (Cuvier); brown bullhead, Ictalurus nebulosus (Lesueur); yellow bullhead, I. natalis (Lesueur); redbreast sunfish, L. auritus (Linnaeus); bluegill, L. macrochirus Rafinesque; spotted sunfish, L. punctatus (Valenciennes); and redfin pickerel, Esox americanus (Gmelin), from the Alabama River Drainage, brown bullhead from the Mobile Bay Drainage in Alabama, and pirate perch, Aphredoderus sayanus Gilliams, from an Atlantic Coast drainage in Georgia. The new genus most closely resembles the genus Acanthocephalus; it differs from this genus in having a distinctive pear-shaped proboscis, a long neck, and hooks which abruptly differ in size.
毛棘头虫属（Pilum pilum）新属及新种是根据来自亚拉巴马河排水区的大口黑鲈（Lepomis gulosus，居维叶）、棕牛头鲇（Ictalurus nebulosus，勒叙厄尔）、黄斑牛头鲇（I. natalis，勒叙厄尔）、红胸太阳鱼（L. auritus，林奈）、蓝鳃太阳鱼（L. macrochirus，拉菲内克）、斑太阳鱼（L. punctatus，瓦朗谢讷）和红鳍狗鱼（Esox americanus，格梅林），亚拉巴马州莫比尔湾排水区的棕牛头鲇，以及佐治亚州大西洋海岸排水区的海盗鲈（Aphredoderus sayanus，吉列姆斯）描述的。这个新属与棘头虫属最为相似；它与该属的不同之处在于有一个独特的梨形吻突、一个长颈部以及大小突然不同的钩。
