Abstract
Parahellenia mizoramensis sp. nov. from Costaceae is described and illustrated as a new species from Northeast India (Mizoram) and represents the only existing species under the genus from India. It differs from its allied species, Parahellenia tonkinensis (Gagnep.) Juan Chen, N.H. Xia, L.Y. Zeng, S. Jin Zeng, and Parahellenia yunnanensis S. Jin Zeng, N.H. Xia, L.Y. Zeng, and Juan Chen by the size and shape of axillary buds, wider bracts, longer calyx and corolla lobes, crenulate margin of labellum, prominent overlapping of labellum margin to form trumpet-shaped, presence of bright red streaks in anther crest, and shape of dorsal appendage in stigma. The newly described species is provisionally assessed as Critically Endangered (CR) based on the available data as per the International Union for Conservation of Nature (IUCN) Red List Categories and Criteria.
本研究描述并展示了来自印度东北部（米佐拉姆）的新种Parahellenia mizoramensis sp.它与同属的 Parahellenia tonkinensis (Gagnep.) Juan Chen、N.H. Xia、L.Y. Zeng、S. Jin Zeng 和 Parahellenia yunnanensis S. Jin Zeng、N.H. Xia、L.Y. Zeng 及 Juan Chen 的区别是和陈娟的腋芽的大小和形状、较宽的苞片、较长的花萼和花冠裂片、唇瓣边缘具细圆齿、唇瓣边缘突出重叠形成喇叭状、花药嵴有鲜红色条纹以及柱头背侧附属物的形状。根据国际自然保护联盟（IUCN）红色名录的分类和标准，根据现有数据，新描述的物种被暂定为极危物种。
