The model examines the relationship between coextinction levels (proportion of species extinct) of affiliates and their hosts across a wide range of coevolved interspecific systems: pollinating Ficus wasps and Ficus, parasites and their hosts, butterflies and their larval host plants, and ant butterflies and their host ants. Applying a nomographic method based on mean host specificity (number of host species per affiliate species), we estimate that 6300 affiliate species are &amp;quot;coendangered&amp;quot; with host species currently listed as endangered. Current extinction estimates need to be recalibrated by taking species coextinctions into account.&lt;/p&gt;
