Binomial name
Neivamyrmex ectopus
Wilson, 1985

This is one of only a handful of species within the subfamily Dorylinae known from fossils. It is also the only known species of Neivamyrmex found within the Greater Antilles, although the genus does occur in the Lesser Antilles. This would suggest that the genus was once more widely spread. Neivamyrmex ectopus appears to be overall more similarity to contemporary Mexican and United States species rather than South American species, suggesting a closer relationship to these northern taxa.
