Dolichoderus semirugosus

Identification
Dill (2002) - A member of the Dolichoderus sulcaticeps species group. Dolichoderus semirugosus can easily be distinguished from all other species of the Dolichoderus sulcaticeps group by its very coarse surface sculpturing. Head, entire alitrunk, and petiolus are coarsely areolate-rugosely wrinkled, dark-brown to black and matt. The species that comes closest to semirugosus regarding the sculpturing is Dolichoderus crawleyi. However, the sculpturing of semirugosus is distinctly coarser, and, moreover, its alitrunk is less shining and more robust.
