Nothing is known about the biology of Stictoponera polytreta.


Lattke (2004) - This species could be confused with Stictoponera pertusa, Stictoponera lacunosa, and Stictoponera rugodens as discussed under S. pertusa. S. pertusa has a very prominent mandibular base, forming a bulging convexity in frontal view, and its subpetiolar process is subquadrate in lateral view, with a sharp posterior angle. Stictoponera rugodens has a more evenly convex dorsal margin of the petiolar node and a relatively shorter declivitous margin to the propodeum compared with the dorsal margin in lateral view; it is also larger bodied (HL > 0.85; HW > 0.65; WL > 1.25 mm) than S. polytreta. Stictoponera lacunosa has a more evenly convex dorsal petiolar node margin, the subpetiolar process forms a rounded lobe in lateral view, the lateral face of the postpetiolar tergite is mostly smooth with punctae on the anterior one-third or less, the dorsal and declivitous propodeal margins form a blunt obtuse angle, more open than in S. polytreta, and the mandibular base is more deeply strigulose in S. lacunosa.

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Lattke 2004 Gnamptogenys fig 45-49

Dorsum of head densely foveolate; oculomalar margin with low triangular projection; lateral mandibular margin slightly sinuate; clypeus convex with faint median convexity; occipital lamella protuberant and convex; anterior petiolar margin broadly concave in dorsal view, without protuberant lateral lobes; anterior and posterior shelves of node form minute acute angles in lateral view with node margins.

Metrics. [Holotype] Paratype: HL [0.77] 0.77, HW [0.59] 0.59, ML [0.37] 0.35, SL [0.51] 0.51, ED [0.19] 0.20, WL [1.13] 1.15 mm. CI [0.76] 0.76, SI [0.87] 0.88, MI [0.63] 0.59, OI [0.33] 0.34. Head with lateral margin separated from posterior margin in frontal view by brief, broadly concave to straight margin; oculomalar margin divided by low triangular projection into longer posterior broad convexity and shorter broadly convex to almost straight anterior margin; frons evenly foveolate; frontal lobe dorsally smooth with shallow elongate depressions, posteriorly bordered by abrupt slope; clypeus posterolaterally strigulose-foveolate, medially with longitudinal strigulae extending to posterior half of clypeal lamella, low rounded ridge extends anterad from frontal lobe; lamella mostly smooth, anterior margin of lamella convex with slight median convexity; mandible slightly sinuate laterally, rugulose-punctate basally, apically mostly smooth with punctae; head with broadly convex dorsal margin in lateral view, interrupted by brief abrupt elevation of frontal lobes posterior margin; frontal lobe and clypeus each form broad convexities; occipital lamella convex and protuberant.

Pronotum laterally foveolate with low longitudinal undulations; mesopleuron mostly smooth with foveolae on anepisternum and particularly along ventral katepisternum; metapleuron triangular, tapering anterodorsally and diverging posteroventrally, anterior margin broadly convex, mostly smooth, longitudinally strigulose ventrally; propodeum undulate with irregular depressions, declivitous and dorsal margins form blunt, slightly obtuse angle in lateral view; mesosoma laterally with broadly convex dorsum, medially almost flat. Petiolar node dorsum mostly smooth with punctae, laterally foveolate; subpetiolar process triangular, projecting anteriorly; postpetiole mostly smooth, laterally fovelate, with anterior foveolae deeper and wider than posterior foveolae, dorsum sparsely punctate; ventral margin of postpetiole mostly straight after process in lateral view, convex posteriorly; fourth abdominal segment mostly smooth, dorsum sparsely punctulae, punctae present along posterior margin. Fore coxae mostly transversely strigulose, smooth anteriorly. Dorsum of thorax and abdominal segments 1-4 with scattered erect to subdecumbent hairs. Body brown, antennae and legs ferruginous brown.

Type Material

Holotype worker. Malaysia, Pahang, Genting Highlands, Awana, 1150m, 3-iv-1993, I. Löbl & Calame #27b. Deposited in Musee d'Histoire Naturelle Genève. Paratype. One worker in The Natural History Museum from Malaysia, Pahang, Genting Highlands, Awana, 1150m, 3-iv-1993, I. Löbl & Calame #27c.


The species name is derived from the Greek terms poly (many) plus tretos (perforated). It alludes to the multiple depressions of its foveolate sculpture.
