Taxonomic notes. Refer to I. aegyptiaca group for a discussion of similar species.

The original description gave the host as “avore das mattas” which translates to “bark of an indigenous tree” and provided the collector’s name ( Hempel, 1900: 375). The World Catalogue did not include this information in the type data ( Ben-Dov, 2005: 219).
