Nomenclature

 *  lipan. Dorymyrmex lipan Snelling, R.R. 1995: 8, figs. 16, 17 (w.) U.S.A.

Worker
Holotype (mm): HL 0.81; HW 0.71; SL 0.79; EL 0.22; TL 2.7. Indices and ratios: CI 88; SI 98; SI2 113; OI 27; OMR 94; IOR 159.

Head broadest slightly above upper eye margin; in frontal view, sides nearly straight below and weakly curved above eyes, broadly and evenly rounded onto vertex, vertex nearly flat. Eye large, OMD about 0.60 times distance from upper eye margin to level of vertex margin.

Promesonotal profile nearly flat, obtusely angulate behind. In profile, basal face of propodeum weakly sinuate, posterior cone erect and sharp; posterior declivity nearly straight.

Mandible shiny, costate for nearly entire length. Head and body shiny, integument weakly tessellate to smooth.

Entire head and body sparsely pubescent, appressed hairs nowhere obscuring surface and not imparting sheen across surface. Erect hairs as described for Dorymyrmex insanus.

Color medium reddish brown, gaster darkest; antennae and legs yellowish.
