Differential diagnosis. Eutarsopolipus savatus sp. nov. is most similar to E. labiatus and the distinguishing features are discussed under the Differential Diagnosis for the latter species.

Etymology. The name savatus (a tender kiss) alludes to both the lip-like protrusion of the gnathosoma but also alludes to the larger size of this species.

Remarks. One larva similar to E. echinatus Seeman, 2019a was found on HR# T82502 ; one male closest to the nahmani subgroup group was found on HR# T82502 (QMS 113499) ( Tables 1 , 2 ).
