Karyotype
Genus Uncertain
The following karyotypes were described as belonging to Trachymyrmex but lacked species-level identifications. As a result of the taxonomic changes proposed by Solomon et al. (2019) the generic placement of these specimens becomes uncertain, but they are likely to belong to either Mycetomoellerius or Paratrachymyrmex rather than Trachymyrmex (based on geographic distribution).
- As Trachymyrmex sp.1: n = 6, 2n = 12, karyotype = 12M (Panama) (Murakami et al., 1998).
- As Trachymyrmex sp.2: 2n = 18, karyotype = 18M (Panama) (Murakami et al., 1998).
- As Trachymyrmex: 2n = 22, karyotype = 18M+4SM (Brazil) (Barros et al., 2013).
