Barbouriidae Christoffersen, 1987 is a family comprised of 4 genera and 11 species of enigmatic shrimps restricted to anchialine or marine caves whose evolutionary history and relationships remain elusive. We investigated the evolutionary relationships among members of Barbouriidae with the inclusion of four genera and nine species, and newly collected material from Belize, the Bahamas, and the Yucatán Peninsula, Mexico. Phylogenetic analyses based on seven mitochondrial and nuclear gene regions and genetic distances calculated using partial 16S gene regions have identified a need to revisit the relationships and classification within Barbouriidae. More specifically, we find evidence to suggest Janicea Manning & Hart, 1984 as a junior synonym of Parhippolyte Borradaile, 1900, B. yanezi Mejía, Zarza & López, 2008 as a synonym of Barbouria cubensis (von Martens, 1872), and define two new subfamilies, Calliasmatinae Holthuis, 1973 and Barbouriinae Christoffersen, 1987. Included is a dichotomous key for the species of Barbouriidae that summarizes previous literature and includes new morphological characters. Our findings shed light on existing inaccuracies and gaps in molecular data from barbouriids. We also provide further clarity into evolutionary relationships among genera of Barbouriidae and their allies, suggesting phylogeographic divisions within the family. Our findings suggest an early Atlantic-Pacific divide among genera originating from a shallow-water reef ancestor.

chi甲碱调整：1987年Barbouriidae Christoffersen家族的最新系统发育和分类（十足目：Caridea）

Barbouriidae Christoffersen，1987年，一个家族，由4属和11种神秘虾组成，只限于an鱼碱或海洋洞穴，其进化历史和关系仍然难以捉摸。我们调查了包括四个属和九种在内的Barbouriidae成员之间的进化关系，以及从伯利兹，巴哈马和墨西哥尤卡坦半岛新采集的材料。根据七个线粒体和核基因区域以及使用部分16S基因区域计算的遗传距离进行的系统进化分析已确定需要重新审视Barbouriidae的关系和分类。更具体地说，我们发现证据表明Janicea Manning＆Hart（1984年）是Parhippolyte Borradaile（1900年）的初级同义词。B. yanezi梅西亚，萨尔萨和洛佩斯，作为2008年的代名词Barbouria霜霉病（冯马丁，1872年），并定义了两个新亚科，Calliasmatinae Holthuis，1973年和Barbouriinae克里斯托弗森，1987年包括对Barbouriidae的该种二分法关键总结了以前的文献，并包括了新的形态特征。我们的发现揭示了Barbouriids分子数据中的现有误差和差距。我们还提供了进一步的清晰的Barbouriidae属及其盟友之间的进化关系，表明该家族内的系统地理学划分。我们的发现表明，起源于浅水礁祖先的属之间存在早期的大西洋-太平洋鸿沟。
