Abstract

Abstract: The Eurycea quadridigitata complex is currently composed of the nominate species and E. chamberlaini, with no other species recognized. However, recent molecular studies have revealed at least five genetic lineages within this species complex, with one lineage more closely related to the neotenic Eurycea species of central Texas and E. chamberlaini nested within E. quadridigitata sensu lato. We use large-scale geographic sampling in combination with a multilocus species delineation method and morphology to test whether these genetic lineages represent distinct species under the general lineage concept of species. We describe two new species of salamander from this complex, resurrect and elevate a former subspecies to full species status, add to the diagnosis of E. chamberlaini, and redefine E. quadridigitata in the context of this revision. All five species are diagnosable from one another through a number of meristic, morphometric, molecular, and ecological criteria.

矮蝾螈(尾纲:多齿螈科:半齿螈科)复合体的修订及两个新种的描述

摘要/ Abstract摘要:Eurycea quadridigitata复合体目前由指定种和张伯伦(E. chamberlaini)组成，未发现其他种。然而，最近的分子研究揭示了该物种复合体中至少有五个遗传谱系，其中一个谱系与德克萨斯州中部的新世Eurycea物种和E. chamberlaini在E. quadridigitata sensu lato中筑巢关系更密切。我们使用大规模的地理采样，结合多位点物种描述方法和形态学来测试这些遗传谱系是否在物种的一般谱系概念下代表不同的物种。我们从这个复合体中描述了两个新的蝾螈物种，复活并提升了一个前亚种到完整种的地位，增加了E. chamberlaini的诊断，并在此修订的背景下重新定义了E. quadridigitata。所有五个物种都可以通过一些分生，形态，分子和生态标准相互诊断。
