The bamboo genus Eremitis is one of the three genera of Parianinae, a subtribe within tribe Olyreae (Poaceae, Bambusoideae). As now understood, Eremitis includes six described species. While surveying the bamboos of Rio Doce State Park, some populations of Eremitis were collected and identified as E. parviflora. However, as part of a taxonomic revision of the genus, these specimens are now recognized as a new species, E. riodocensis, which is described and illustrated herein. It differs consistently from E. parviflora and other morphologically similar species in multiple morphological characters, as well as in its geographical distribution. The area where it was collected, about 294 km from the coast, represents the most inland distribution of the genus. Following the IUCN Red List categories and criteria, we assess its conservation status to be Endangered (EN). Comments on the morphology, taxonomic relationships, and habitat of the new species are provided.

来自巴西米纳斯吉拉斯州里奥多西州立公园的一个新种(禾本科,竹科)标志着该属的最远内陆分布

竹属Eremitis是Parianinae的三个属之一,是Olyreae部落(禾本科,Bambusoideae)中的一个亚部落。正如现在所理解的,Eremitis 包括六个描述的物种。在调查 Rio Doce 州立公园的竹子时,收集了一些 Eremitis 种群并确定为 E. parviflora。然而,作为该属分类学修订的一部分,这些标本现在被认为是一个新物种,E.riodocensis,在本文中进行了描述和说明。它与 E. parviflora 和其他形态相似的物种在多个形态特征以及地理分布方面始终不同。它的采集地区距海岸约 294 公里,是该属分布最内陆的地区。遵循 IUCN 红色名录类别和标准,我们评估其保护状态为濒危 (EN)。提供了对新物种的形态、分类关系和栖息地的评论。
