Abstract

Primulina lipuensis, a new cave-dwelling species from limestone areas of Guangxi, China, is described and illustrated here. It is morphologically similar to P. guihaiensis (Y.G.Wei, B.Pan & W.X.Tang) Mich.Möller & A.Weber, but can be distinguished by multiple morphological characters, particularly in the number of staminodes and the shape of the stigma. Furthermore, phylogenetic analyses based on nrITS and trnL-F sequences indicate that P. lipuensis is distantly related to P. guihaiensis, supporting the recognition of P. lipuensis as a distinct new species. According to IUCN category and criteria, it is accessed to be Vulnerable (VU D2).
