We describe an extraordinary new species in the genus Thismia from the Terengganu State of Malaysia in the Malay Peninsula. The new species, which we name Thismia sitimeriamiae, is distinct from all other Thismia species known to science, most notably in its unique mitre configuration formed by the inner tepals and its floral surface morphology characterised by conspicuous orange trichomes. We discuss our findings in the context of underestimated species diversity in the genus Thismia and implications for their conservation. We recommend assigning T. sitimeriamiae the conservation status as Critically Endangered (CR) according to IUCN criteria.

Thismiasitimeriamiae（Thismiaceae），来自马来西亚半岛登嘉楼的一个非凡的新物种

我们描述了来自马来半岛马来西亚登嘉楼州的 Thismia 属中的一个非凡的新物种。我们将这个新物种命名为 Thismia sitimeriamiae，与科学界已知的所有其他 Thismia 物种不同，最显着的是其由内部花被形成的独特斜接构造和以显眼的橙色毛状体为特征的花卉表面形态。我们在 Thismia 属的物种多样性被低估的背景下讨论我们的发现及其对保护的影响。我们建议根据 IUCN 标准将 T.sitimeriamiae 的保护状态指定为极危 (CR)。
