Abstract

Summary Four new species of Matelea , endemic to Mexico, are proposed and described: M. balrog, M. cornuta, M. jaimesiae and M. lokii. These taxa differ from each other and M. gonoloboides , M. medusae and M. porphyrantha (the Matelea gonoloboides species complex) in their corolla shapes and gynostegial corona ornamentation. Descriptions, illustrations, morphological comparisons and geographic distributions of these species, as well as their conservation status, are provided. A lectotypification for the name M. gonoloboides is also included . These discoveries highlight Mexico as a centre of diversity and endemism for the genus, with 69 species currently known from the country, of which 66% are restricted to it.

标题墨西哥特有麻麻属四新种(夹竹桃科:麻麻科)

提出并描述了墨西哥特有的4个新种:M. balrog、M. cornuta、M. jaimesiae和M. lokii。这些分类群在花冠形状和雌蕊花冠纹饰上不同于其他分类群，也不同于M. gonoloboides、M. medusae和M. porphyrantha (Matelea gonoloboides种群)。本文提供了这些物种的描述、图例、形态比较、地理分布及其保护状况。还包括名称淋球菌的lectotypification。这些发现突出了墨西哥是该属的多样性和地方性中心，目前在该国已知的69种，其中66%仅限于它。
