Stachytarpheta is mainly distributed in Brazil, where the knowledge of species richness is still in progress. Here, we describe S. meninii, a new micro-endemic species from the Diamantina Plateau, Espinhaço Range. It is a shrub that can reach up to 1.8 meters in height, with abundant pedicellate glandular trichomes, viscous, aromatic leaves, inflorescences with oblong-triangular bracts, and blue corollas, with a tube that is barely exserted from the calyx. The new species has been recorded from two gatherings from the same locality in the municipality of Serro, Minas Gerais state, and can be considered Critically Endangered (CR). Illustrations and a distribution map are provided for the recognition of S. meninii, along with an identification key for species of the genus found in Diamantina Plateau.

Stachytarpheta meninii（马鞭草科），巴西米纳斯吉拉斯州迪亚曼蒂纳高原的一种新的微型特有和受威胁物种

Stachytarpheta主要分布在巴西，对该国物种丰富度的了解仍在进行中。在这里，我们描述了S. meninii，一种来自埃斯皮尼亚索山脉迪亚曼蒂纳高原的新微型特有物种。它是一种灌木，高度可达1.8米，有丰富的有花梗腺毛，粘性芳香的叶子，花序有长方形三角形的苞片，蓝色的花冠，有一个几乎不从花萼伸出的管子。该新物种是在米纳斯吉拉斯州塞罗市同一地点的两次采集中记录到的，可被视为极度濒危（CR）。提供了用于识别S. meninii的插图和分布图，以及在迪亚曼蒂纳高原发现的该属物种的识别关键码。
