Stictoponera paso

Nothing is known about the biology of this species.

Identification
Lattke (2004) - This species comes close to Gnamptogenys binghamii in the key. G. binghamii can be separated from G. paso by its smaller size (HL < 1.5; WL < 2.0 mm) and evenly convex petiolar node when seen laterally, as well as the lamellate humeral angle. The head of the holotype is detached and separately mounted on the same pin as the body.

Distribution
Known only from Malaysia

This taxon was described from West Malaysia.

Castes
Queen and male are unknown.

Nomenclature

 *  paso. Gnamptogenys paso Lattke, 2004: 143, fig. 33 (w.) WEST MALAYSIA.

Head with sinuate lateral margins in frontal view, slightly concave near eyes, convex anterad. Anterior margin of clypeal lamella converging toward median blunt point, laterally bluntly angular. Mesosomal dorsum mostly smooth with scattered foveolae laterally, plus scattered shallow patches of longitudinal undulations. Petiolar node with dorsal margin higher posterad than anterad in lateral view; anterior margin straight and vertical, dorsal margin broadly convex, posterior margin steeply descending.

Head with lateral margins sinuate in frontal view, slightly concave near eyes, convex anterad; posterior margin concave, anterior margin of clypeal lamella converging toward median blunt point, laterally bluntly angular; frons strigulose-punctate, strigulae continuing onto cephalic sides; clypeus longitudinally strigulose; scape with variable smooth and strigulose areas, most strigulae present apically; occipital lobe present; occipital lamella convex, parallel sided. Mesosoma mostly foveolate in lateral view, pronotal background sculpture mostly smooth dorsally, strigulose ventrally and on mesopleuron; pronotum with anterodorsal margin strigulose-punctate, anteroventrally bluntly angular, humeral angle not lamellate; mesosomal dorsum mostly smooth with scattered foveolae laterally, plus scattered, shallow longitudinal undulations; anterodorsal metapleuron mostly smooth, posteroventral metapleuron longitudinally strigulose; propodeal dorsum with more foveolae and strigulae, propodeal declivity mostly smooth, with triangular denticles.

Petiolar dorsum mostly smooth with scattered foveolae, node with dorsal margin higher posteriorly than anteriorly in lateral view, anterior margin straight and vertical, dorsal margin broadly convex, posterior margin steeply descending; ventral petiolar process forms anteriorly projecting triangular lobe; postpetiolar dorsum mostly smooth with scattered shallow punctae, anterolaterally with oblique strigulae; sternum mostly smooth with lateral and posterolateral strigulae; fourth abdominal tergite mostly smooth with scattered punctulae, sternum smooth. Fore coxa transversely strigulose in lateral view, especially along posterior half; fore tarsus opposite strigil with row of stout setae; metacoxal tooth straight with posterior flange. Dorsum of thorax and abdominal segments 1-4 with few, scattered erect to subdecumbent hairs. Head, mesosoma, petiole, and gaster ferruginous-brown; mandibles, antennae, legs ferruginous.
