Description
The “real” costifer with rough surface. DNA analysis shows that there is a 10% difference compared to the smooth specimens that were offered before. That means, the previously sold “costifer” could be a new species. All these while, it has always been dextral specimens collected. This actual species has both dextral & sinistral. Collected by locals in the forest, October 2019. Extremely difficult to get a good matching pair in acceptable quality of this very rough species.
