Worker
(holotype in parentheses). TL 4.6–5.1 (5.0), HL 1.00–1.10 (1.02), HW 0.79–0.92 (0.83), CI 79–85 (81), SL 0.80–0.96 (0.88), SI 99–111 (106), PW 0.58–0.68 (0.62), WL 1.30–1.42 (1.34), MfL 1.02–1.18 (1.10) (20 measured).

Very similar to, and mostly matching the description of, Myrmisaraka producta, but with an obviously 3-segmented antennal club, in which funiculus segment 8 is only 1.00–1.25 times longer than broad, and funiculus segment 9 is relatively elongated, 1.70–2.00 × longer than funiculus segment 8. The antennal scape is relatively shorter in brevis, SI 99–111, than in producta, SI 115–129. In addition, the head capsule of producta averages relatively slightly narrower, CI 75–80, as opposed to CI 79–85 in brevis.
