Two new records for this species are presented. Its Ibero-Balearic distribution and the available dates of the presence of winged queens and a male, between the end of sum- mer and the beginning of autumn, are updated.

Ant-loving crickets are kleptoparasites living in ant nests. This work aims to sum up the current knowledge on the known distribution and host ant preferences of three Myrmeco- philus crickets found in the Iberian Peninsula and Balearic Islands: M. ochraceus, M. fuscus and M. acervorum. Older literature was carefully reviewed, while recent literature, parti- cularly after the description of M. fuscus, was prioritized to minimize the use of outdated vÀ>Ì>`Ài`ÕViÌ iÀÃvÃ`iÌwV>Ìð/ iÃÌÕ`ÞÕ`iÀÃVÀiÃÌ iii`vÀ Ài`iÌwV>Ìv`ëiViÃ>`Ì iÀ ÃÌÃ} ÌvÀiViÌ`ÃVÛiÀiÃ]«ÀÛ`} a review of the current understanding of the myrmecophilous crickets.
