根据骨骼学、外部解剖学和消化道解剖学，对下口鱼亚科和钩鱼亚科几乎所有属的系统发育进行了分析。结果表明，下口亚科是一个并系组合。Delturus和Upsilodus形成了一个单系群姐妹所有其他的Loricariids。Hemipsilichthys，Isbrueckerichthys，Kronichthys和Pareiorhina与Neoplecostomus和Hypoptopomatinae形成一个单系群，并转移到Neoplecostominae。下口虫亚科的其余部分由于对钩虫亚科的继续认识而成为并系的。Ancistrinae回到下口亚科，并被确认为一个部落，Ancistrini。此外，还描述了四个新族（Corymbophanini，Hypostomini，Pterygoplichthini和Rhinelepini）。下口龙属也是并系的，其大部分与隐圆藻属、旋齿龙属和等线甲鲶属形成一个单系分支。下口龙属内所有潜在的单系类群都是彼此递变的;因此，隐圆虫属、旋齿龙属和等线甲鲶属都是下口龙属的同义词。Pterygoplichthys和Glyptoperichthys也是多系的，Liposarcus和Glyptoperichthys被认为是Pterygoplichthys的同义词。翼甲鱼的姊妹是连接半钩鲶（Hemiancistrus annectens），包括巴拿马下口鲶（Hypostomus panamensis），代表一个未描述的属。提出的遗传学与以前的假设进行了比较。(C)2004年，伦敦林奈学会。
A phylogenetic analysis of nearly all genera of the Hypostominae and the Ancistrinae is provided based on osteology, external anatomy, and digestive tract anatomy. The results suggest that the Hypostominae is a paraphyletic assemblage. Delturus and Upsilodus form a monophyletic group sister to all other loricariids. Hemipsilichthys, Isbrueckerichthys, Kronichthys, and Pareiorhina form a monophyletic group with Neoplecostomus and the Hypoptopomatinae and are transferred to the Neoplecostominae. The remainder of the Hypostominae is made paraphyletic by the continuing recognition of the Ancistrinae. Ancistrinae is returned to the Hypostominae and recognized as a tribe, Ancistrini. In addition, four new tribes (Corymbophanini, Hypostomini, Pterygoplichthini, and Rhinelepini) are described. Hypostomus is also paraphyletic, the bulk of it forming a monophyletic clade with Aphanotorulus, Cochliodon, and Isorineloricaria. All of the potential monophyletic groups within Hypostomus grade into one another; therefore, Aphanotorulus, Cochliodon, and Isorineloricaria are placed in the synonymy of Hypostomus. Pterygoplichthys and Glyptoperichthys are also polyphyletic, and Liposarcus and Glyptoperichthys are recognized as synonyms of Pterygoplichthys. Sister to Pterygoplichthys is the Hemiancistrus annectens group (including Hypostomus panamensis) which represents an undescribed genus. The phylogeny presented is compared with previous hypotheses.
