Differential diagnosis. Eutarsopolipus hebronae   sp. nov. differs from E. despoticus   sp. nov. by having a much larger gnathosoma   (61–65 × 60–67 versus 45–51 × 47–51) and cheliceral stylets (75–84 versus 50–55). The species also differ in the size of setae tc″ on tarsi II-III, being much larger in E. hebronae   (3–4) than E. despoticus   (2–3). Even though these setae are only about 1 μm longer, they are obviously larger, being around twice as massive in E. hebronae   . These differences in gnathosomal size and tarsal setae are present in the adult and larval female.

Etymology. It is with great pleasure that I name this species for Wendy Hebron, with whom I have shared the role of collection manager for 14 years. Not only has her welcome and proficient assistance in the Queensland Museum arachnology collection been greatly appreciated, but her fine efforts have allowed me to dedicate more time to acarology.

Remarks. This species was found co-infesting its host species with E. umbonatus   sp. nov. and an undescribed species of Eutarsopolipus   close to E. echinatus Seeman, 2019a   ( Tables 1, 2).

The ochoai species group - basiatus   subgroup

Diagnosis. Female with dorsal idiosomal setae fine, slender; setae h minute or alveolar vestiges. All life stages with gnathosomal apex with small paired lobes.
