Abstract

High-throughput sequencing, when combined with taxonomic expertise, is a powerful tool to refine and advance taxonomic classification, including at the species level. In the present work, a new species, , is described out of the species complex, based on phylogenomic and morphological evidence. The main morphological characters that distinguish the new species from are the glabrous posterior sepals and the slightly broader leaves. The new species is known from only three localities, all in natural high-elevation grasslands in Paraná and Santa Catarina states, southern Brazil. According to the IUCN criteria new species should be assessed as Endangered (EN). We present field photographs of and related species, and we provide an identification key to the species previously included within the circumscription of .

摘要

高通量测序与分类学专业知识相结合时，是完善和推进分类学分类（包括在物种水平上）的有力工具。在本研究中，基于系统基因组学和形态学证据，从一个物种复合体中描述了一个新物种。将新物种与其他物种区分开来的主要形态特征是后萼片无毛以及叶片略宽。该新物种仅在巴西南部巴拉那州和圣卡塔琳娜州的天然高海拔草原的三个地点被发现。根据国际自然保护联盟（IUCN）的标准，新物种应被评估为濒危（EN）。我们展示了该新物种及相关物种的野外照片，并提供了先前包含在该分类范围内的物种的鉴定检索表。
