A phylogenetic analysis is provided for representatives of more than one hundred species of the catfish family Loricariidae, including nearly all genera of the subfamilies Neoplecostominae and Hypoptopomatinae. This analysis is based on fragments of the subunit 1 of the cytochrome c oxidase gene (COI), the recombination activating genes 1 (RAG1) and 2 (RAG2), and the F-Reticulon 4 gene. We obtained an alignment of 4678 contiguous nucleotides for 136 species of 50 loricariid genera from five loricariid subfamilies, and ten outgroup species from five loricarioid families. Our results from Maximum Parsimony, Maximum Likelihood, and Bayesian analyses show the following set of interrelationships ((((Hypoptopomatinae, Neoplecostominae) Hypostominae), Loricariinae) Delturinae). However, neither Hypoptopomatinae nor Neoplecostominae were recovered as monophyletic groups. A previously hypothesized monophyly of Hypoptopomatini and Otothyrini was refuted. Furthermore, the genera Pareiorhaphis, Pareiorhina, Hisonotus and Parotocinclus were recovered as polyphyletic.
提供了一百多种甲鲶科鱼类，包括近所有副鲶亚科和拟甲鲶亚科属的代表种的系统发育分析。该分析基于细胞色素 c 氧化酶亚基 1（COI）、重组激活基因 1（RAG1）和 2（RAG2）以及 F-Reticulon 4 基因的片段。我们从五个甲鲶亚科的 50 个甲鲶属的 136 个种和五个甲鲶总科的十个外群种中获得了 4678 个连续核苷酸的排列。我们的最大简约法、最大似然法和贝叶斯分析结果显示了以下的种系发生关系（(((Hypoptopomatinae, Neoplecostominae) Hypostominae), Loricariinae) Delturinae）。然而，Hypoptopomatinae 和 Neoplecostominae 都没有被恢复为单系群。先前假设的 Hypoptopomatini 和 Otothyrini 的单系性被反驳了。此外，Pareiorhaphis、Pareiorhina、Hisonotus 和 Parotocinclus 属被恢复为多系群。
