Nothing is known about the biology of Stictoponera treta.
Identification
Lattke (2004) - This species is similar to Stictoponera paso and Stictoponera binghamii in the key. It may be further separated from S. paso by the larger size (HL > 1.6; WL > 2.3 mm) of S. paso. Also, the petiolar node of G. paso has a very broad dorsal margin, higher posterad than anterad, and the subpetiolar process has a posterior blunt angle. S. treta is slightly larger than S. binghamii, which has occipital lobes and a lamellate humeral angle.

Description
Worker
Metrics. Holotype: HL 1.43, HW 1.18, ML 0.86, SL 1.34, ED 0.22, WL 2.08 mm. CI 0.83, SI 1.14, MI 0.73, OI 0.19. Head subquadrate in frontal view, widest anterad, lateral margins convex, posterior margin concave, anterior margin of clypeal lamella medially triangular with bluntly angular sides; frons and vertex densely foveolate; clypeus longitudinally strigulose with strigulae extending onto lamella; scape mostly smooth with scattered piligerous punctae; occipital lobes absent; occipital lamella well developed, convex. Pronotum foveolate, humeral angle small; anepisterum cuneiform, mostly smooth with scattered punctae; katepisternum foveolate with rugosity along posteroventral margin; metapleuron smooth anterodorsally, posteroventrally strigulose-punctate; propodeal declivity mostly smooth with transverse strigulae anterad; mesosomal dorsum foveolate, without transverse sutures, with median longitudinal smooth area. Mesosoma with convex dorsal pronotal margin in lateral view, mostly flat mesometanotum, convex dorsal propodeal margin and concave declivity. Petiolar node with subpetiolar process projecting anterad as sharply pointed triangular lobe in lateral view; postpetiolar dorsum foveolate, depressions becoming progressively smaller and less numerous posterad, sternum mostly smooth; dorsum of abdominal segment 4 mostly smooth with scattered punctulae, sternum mostly smooth with sparse punctae. Fore coxa transversely strigulose in lateral view; fore tarsus opposite strigil with row of stout setae; metacoxal tooth low, triangular. Dorsum of thorax and abdominal segments 1-4 with scattered erect to subdecumbent hairs. Head, mesosoma, petiole, and gaster ferruginous brown; mandibles, antennae, legs ferruginous.
Type Material
Holotype worker. Malaysia, Sabah, 7km N Tembunen, 700m, 20-v-1989, I. Löbl & D. Burckhardt 32a. Deposited in The Natural History Museum. Paratype. One worker in the BMNH with the same data as the holotype.
Etymology
The species name alludes to its foveolate cuticle and is derived from the Greek for “perforated,” tretos.
