Achard (deposited in the NMP), but did not select one as the holotype . Thus, all specimens are syntypes . He retained multiple specimens for his collection, which were afterwards exchanged with different collectors and institutions. The ZMH specimen is part of the type series, which we examined in NMP and MM. The type series is consistent, and there is no need for a lectotype designation.
