Differential diagnosis. Eutarsopolipus despoticus sp. nov. is most similar to E. hebronae sp. nov., but differs by having a smaller gnathosoma , cheliceral stylets and setae tc″ on tarsi II-III. See below the Differential diagnosis of E. hebronae sp. nov. for further details.

Etymology. The host’s specific name porphyriaca refers to its purple wings, and as the colour purple was associated with rulers, the name despoticus (a despot, a tyrant) alludes to this species living beneath the purple wings of its host while engaged in a parasitic life style.
