Nothing is known about the biology of Hypoponera surda, which is only known from type material.
Identification
Bolton and Fisher (2011) - Among the species that possess cuticular ridges at the base of the posterior face of the petiole node, Hypoponera surda is fairly distinct. The two species Hypoponera faex and Hypoponera hebes have very coarse cephalic and pronotal sculpture, whereas in surda the cephalic sculpture is fine and almost effaced on the pronotum. In addition, faex is much larger (HW 0.72) and has well-developed eyes, while hebes has a broader petiole node (PeNI 80–84) and very obvious long, standing setae on the first and second gastral tergites dorsally; these are much longer and more conspicuous than those of surda. The remaining species, Hypoponera mixta, Hypoponera jeanneli, Hypoponera jocosa, Hypoponera quaestio and Hypoponera ursa, have more densely packed punctate sculpture on the disc of the second gastral tergite, and have petiole nodes that are not distinctly thickly D-shaped in dorsal view.
A member of the abeillei group.

Description
Worker
(holotype in parentheses). Measurements: HL 0.63–0.68 (0.66), HW 0.52–0.56 (0.54), HS 0.585–0.620 (0.600), SL 0.46–0.48 (0.48), PrW 0.40–0.42 (0.42), WL 0.86–0.90 (0.88), HFL 0.48 (0.48), PeNL 0.19–0.21 (0.20), PeH 0.40–0.45 (0.45), PeNW 0.28–0.30 (0.30), PeS 0.297–0.317 (0.317) (5 measured). Indices: CI 82–83 (82), SI 86–91 (89), PeNI 69–71 (71), LPeI 44–50 (44), DPeI 140–150 (150).
Eyes absent. Apex of scape, when laid straight back from its insertion, just fails to reach, or just touches, the midpoint of the posterior margin in full-face view; SL/HL 0.71–0.75. Cephalic dorsum finely reticulate-punctate. Pronotal dorsum almost smooth, obviously much less strongly and densely sculptured than cephalic dorsum. Metanotal groove absent from dorsum of mesosoma. Mesonotal-mesopleural suture absent from side of mesosoma. Propodeum weakly marginate between declivity and side. Posterior surface of petiole node with a series of very short cuticular ridges that radiate upward from the peduncle. Node of petiole in profile with the anterior and posterior faces parallel, the dorsum shallowly convex. Petiole node in dorsal view thickly D-shaped, posterior face transverse and anterior face strongly and quite narrowly convex. Subpetiolar process blunt or with a feeble ventral angle. Maximum width of first gastral tergite in dorsal view greater than width of second gastral tergite at its mid-length. Cross-ribs at base of cinctus of second gastral tergite conspicuous. Midline length of second gastral posttergite, from posterior margin of cinctus to apex, is about equal to the width of the segment at its midlength. Disc of second gastral tergite with small punctures that are relatively widely spaced and separated by areas of glossy cuti-cle; the diameters of the punctures are less than the distances that separate the punctures. First and second gastral tergites dorsally pubescent and with a number of short standing setae that project above the level of the pubescence.
