Another undescribed morphospecies, JTL158, also has the same sharp harlequin color and is always sympatric with this species. But the two species are not closely related, and the major workers are entirely different. The minor workers are quite similar, but JTL158 can be distinguished by the smooth shiny dorsum of the pronotum. The pronotal dorsum is always foveolate in JTL189.
These appear to be two members of a mimicry complex that occurs in the Honduras highlands. There are similarly-patterned species of Tapinoma and Brachymyrmex. All are in the same size range; the Pheidole and Brachymyrmex have black head and gaster, bright orange and sharply contrasting mesosoma; the Tapinoma is similar but has bright orange head and mesosoma, black gaster.
