Identification

One of two species that comprise the Dolichoderus monoceros species group. These ants are readily recognizable by the large cone shaped structure on their propodeum. The two species in this group can be differentiated by the following:

  • Head an alitrunk coarsely sculptured, matte; shoulder-corners of pronotum expanded to small cones . . . . . Dolichoderus tricornis
  • Head and alitrunk shiny, not coarsely sculptured; pronotum shoulder-corners not expanded to cones . . . . . Dolichoderus monoceros
