Yantaromyrmex constrictus

This species was transferred from Hypoclinea to Bothriomyrmex by Dalla Torre (1893), then to Iridomyrmex by Wheeler (1915b) and finally to Anonychomyrma by Shattuck (1992a), this final treatment being accepted by Dlussky (1997). It should be noted, however, that extant species of Anonychomyrma are restricted to Indonesia, Papua New Guinea, Australia and the Solomon Islands (Shattuck, 1992a, 1992b; Ward et al., 2010) while this and other fossil species currently placed in Anonychomyrma are well outside this geographic area. The possibility that these species would be better placed in a genus other than Anonychomyrma, probably newly erected specifically for them, cannot be ruled out.

Distribution
This taxon was described from Baltic Amber (Eocene).
