Moss cushions represent an interesting, but poorly understood habitat, which hosts many species of flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini). However, the diversity of moss-inhabiting flea beetles is not well studied, and collecting in tropical and subtropical locations that were not sampled in the past led to the discovery of many new species (Konstantinov et al. 2013). Here, a new species of a moss-inhabiting flea beetle from the genus Cangshanaltica Konstantinov et al. 2013 is described and illustrated. This genus is one of the recently described moss-inhabiting flea beetle genera and before this study, only one species was known (Konstantinov et al., 2013). This publication raises the number of flea beetle species that are known to occur in moss cushions around the world to 30, distributed among 15 genera.
