In the online journal CheckList a paper just has been published on a rare strophocheilid species, Mirinaba cadeaqdensis (Morretes, 1952). The paper by Birckolz et al. gives data on 11 new localities where this species has been found, of which one specimen alive. The species has been found from 30–700 m altitude in protected patches of Atlantic Rainforest. As the authors note, the conservation of this species would require further data on the morphological variation, distribution and ecology. May I suggest also anatomical and molecular data?
