Worker
Minor. Holotype measures HW 1.03, HL 0.96 (CI 107), ML 0.80 (MI 83), SL 1.29 (SI 126), EL 0.21, HFL 1.42 (FLI 148; FWI 18) mm. Very similar in all respects to Acanthomyrmex ferox, except head lacking sculpture dorsally and with only traces of rugae laterally and beneath head. The head sculpture is strongly developed in all A. ferox specimens, including one from the same locality as the Acanthomyrmex laevis holotype.

In addition, the petiolar node of A. laevis has somewhat longer petiolar spines than in A. ferox specimens, and the crotch between the spines is relatively narrow basally (in ferox, the crotch has a wide, convex base). A well-defined subpetiolar declivity is lacking, although a feeble declivity occurs. Node of postpetiole smooth (as in some A. ferox). Pronotal angle not forming a feeble tooth. Uniform dark orange red.

Type Material
Holotype. Minor worker deposited in from Peninsular Malaysia: Perak: Ringlet Pass, 28 Feb. 1982 (M. Kubota).

Etymology
