Nothing is known about the biology of this species.


Lattke (2004) - Stictoponera pertusa may be confused with Stictoponera lacunosa because of the angular anterior clypeal lamella margin and with Stictoponera polytreta because of the prominent occipital lamella. Stictoponera rugodens also has these same traits, but the deep mandibular rugosities easily distinguish S. rugodens. S. lacunosa has more deeply strigulose sculpturing on the mandibular base than S. pertusa, and the mandibular base in S. lacunosa is not as bulging and convex as in S. pertusa. The dorsal margin of the petiolar node in S. lacunosa is more evenly convex, and the subpetiolar process is shaped as a rounded lobe; the postpetiolar tergite is mostly smooth in lateral view with punctae present on the anterior third or less. S. polytreta has a convex mandibular base but not as bulging as in S. pertusa, the subpetiolar process is triangular with a blunt posterior angle, and the dorsal margin of the petiolar node is more evenly convex. The node in S. pertusa has a sharper anterior curvature.

Metrics. [Holotype] Paratype: HL [0.70] 0.69, HW [0.55] 0.53, ML [0.31] 0.30, SL [0.43] 0.43, ED [0.15] 0.13, WL [0.97] 0.95 mm. CI [0.76] 0.77, SI [0.76] 0.81, MI [0.55] 0.55, OI [0.27] 0.25. Head with subparallel sides in dorsal view; foveolae on frons with intervening spaces broad or broader than average diameter of foveolae; clypeus with anteromedian smooth to undulated area, laterally with longitudinal strigulae, lamella translucent with background lighting, anterior margin convex; mandible with convex bulging base; dorsally rugulose-punctate, apically mostly smooth; very small, broadly separated denticles present on chewing border; head with evenly convex occipital lamella in lateral view; posterodorsal mandibular margin with brief, mostly straight margin, then with pronounced convexity in lateral view.

Pronotum laterally foveolate along dorsal half, mostly smooth on ventral half, strigulae present along posterior edge; anepisternum rhomboid, smooth with some punctae; katepisternum mostly smooth, with shallow strigulae along anterodorsal corner; metapleuron and propodeum mostly smooth, longitudinal strigulae present along ventral area of metapleuron; propodeum foveolate, propodeal declivity sharply defined laterally by low crests. Dorsum of mesosoma and petiole sparsely foveolate, mostly smooth especially along longitudinal median strip; petiole with ventral process anteriorly convex in lateral view, ending in a posterior angle; postpetiole laterally with close and deep foveolae anterad, posteriorly becoming shallow and sparse; postpetiolar dorsum mostly smooth with sparse, shallow, piligerous punctae; fore coxa transversely strigulose along posterior half, smooth anterad. Dorsum of thorax and abdominal segments 1-4 with scattered erect to subdecumbent hairs. Body dark brown; legs, antennae, and mandibles ferruginous brown.

Type Material

Holotype worker. Malaysia, Sabah, Borneo, mi. 45 Labuk Road, ex Sandakan (Lungmanis), 12/13-vi-1968, R.W. Taylor, acc. 68.502. Deposited in Australian National Insect Collection. The holotype of G. pertusa is decapitated, with body and head mounted on separate points. Paratype. One callow worker on same pin as holotype, deposited in ANIC.


The species name is derived from the Latin adjective for “perforated,” pertusus, and alludes to the depressions of its foveolate sculpturing.
