Delkeskamp 19 [printed] 57 [handwritten]”; MZSP . Distribution North Brazil , Bolivia . Remarks There is no morphological difference between M. cordiger and M . zischkai . Mycotretus cruciger ( Fig. 5E ) is morphologically similar to M. cordiger , but their lectotypes show phenotypic differences, such as the comparatively larger pronotal and elytral spots in M. cruciger . Nevertheless, as we do not have males of M. cruciger at hand, we prefer not to synonymize it with M. cordiger at this moment.
