A member of the Tetraponera ambigua-group.
Ward (2018) - This species can be readily distinguished from Tetraponera ambigua by its smaller size, disproportionately larger eyes, and much sparser standing pilosity. The anterior clypeal margin of queens and soldiers is adorned with a single median tooth, especially stout in soldiers (anterior clypeal margin usually crenulate or bluntly tridentate in queens and soldiers of T. ambigua). For differences between T. ophthalmica and Tetraponera parops see under the latter species.

Ward (2018) - (n = 11). HW 0.52 - 0.59, HL 0.71 - 0.88, LHT 0.46 - 0.56, CI 0.67 - 0.73, FCI 0.15 - 0.19, REL 0.45 - 0.50, REL2 0.64 - 0.71, SI 0.60 - 0.65, SI3 0.85 - 0.96, FI 0.42 - 0.47, PLI 0.47 - 0.56, PWI 0.35 - 0.46, LHT / HW 0.89 - 0.99, CSC 2 - 4, MSC 0 - 2.
Relatively small species with elongate head and large eyes; masticatory margin of mandible with four teeth; clypeus narrow and protruding anteromedially; median lobes of antennal sclerites expanded laterally and covering most of the antennal insertions; ocelli absent (represented at most by small flecks of dark pigment below the cuticle); profemur moderately slender; pronotum laterally submarginate; mesosonotum flat to weakly convex in profile, metanotal spiracles not conspicuously raised; dorsal face of propodeum rounding insensibly into declivitous face; petiole slender, about twice as long as high; metabasitarsal sulcus absent. Integument finely coriarious/puncticulate and sublucid. Standing pilosity sparse (see CSC and MSC values), absent from the mesonotum and propodeum; typically one pair of long setae on pronotum and petiole, and one or two pairs of shorter setae on postpetiole; scattered appressed pubescence on most of body, moderately dense on abdominal tergite 4 (hairs separated by less than their lengths). Usually pale yellow to yellowish-brown, occasionally much darker (blackish-brown).
