Species of Farfantepenaeus support economically important shrimp fisheries throughout the Western Hemisphere, necessitating proper fisheries management. To be effective, species management should be informed of the potential presence of cryptic species and of the evolutionary forces driving biodiversity. This is best accomplished through a robust phylogenetic framework and evidence-based species delimitation. This study represents the first comprehensive molecular phylogeny and species delimitation analyses of shrimps belonging to the genus Farfantepenaeus. Targeting three mitochondrial genes (12S, 16S, and COI), gene trees and a phylogeny for the genus were inferred using maximum likelihood and Bayesian approaches. In general, the phylogenetic relationships inferred here largely agree with those recovered from morphological data, including the most recent designation of F. isabelae as sister to F. subtilis. Molecular divergence was found between northern and southern populations of F. brasiliensis, suggesting the existence of unrecognised subspecies. However, previous recognition of F. duorarum and F. notialis as two distinct species was not supported by this study. The phylogeny inferred here also uncovers a phylogeographic signal of latitudinal speciation in the genus. The study presented here provides valuable insight into the evolutionary history of Farfantepenaeus, improving our ability to effectively manage these economically important species.

树上的钱生长：具有重要经济意义的粉红虾（Decapoda：Farfantepenaeus）的第一个包容性分子系统发育揭示了神秘的多样性

Farfantepenaeus 物种支持整个西半球具有重要经济意义的对虾渔业，需要适当的渔业管理。为了有效，物种管理应该被告知隐性物种的潜在存在和驱动生物多样性的进化力量。这最好通过强大的系统发育框架和基于证据的物种划分来实现。这项研究代表了属于 Farfantepenaeus 属的虾的首次综合分子系统发育和物种定界分析。使用最大似然和贝叶斯方法推断针对三个线粒体基因（12S、16S 和 COI）、基因树和该属的系统发育。总的来说，这里推断的系统发育关系与从形态学数据中恢复的关系大体一致，包括最近将 F. isabelae 指定为 F. subtilis 的姐妹。在 F. brasiliensis 的北部和南部种群之间发现了分子差异，表明存在未被识别的亚种。然而，本研究不支持先前将 F. duorarum 和 F. notialis 视为两个不同的物种。这里推断的系统发育还揭示了该属中纬度物种形成的系统地理学信号。此处介绍的研究提供了对 Farfantepenaeus 进化历史的宝贵见解，提高了我们有效管理这些具有重要经济意义的物种的能力。本研究不支持先前将 F. duorarum 和 F. notialis 识别为两个不同的物种。这里推断的系统发育还揭示了该属中纬度物种形成的系统地理学信号。此处介绍的研究提供了对 Farfantepenaeus 进化历史的宝贵见解，提高了我们有效管理这些具有重要经济意义的物种的能力。本研究不支持先前将 F. duorarum 和 F. notialis 识别为两个不同的物种。这里推断的系统发育还揭示了该属中纬度物种形成的系统地理学信号。此处介绍的研究提供了对 Farfantepenaeus 进化历史的宝贵见解，提高了我们有效管理这些具有重要经济意义的物种的能力。
