Gnamptogenys gabata casent0179970 p 2 high.jpg

The types were collected at the edge of a primary montane forest. Nothing else is known about the biology of this species.


Modified from Lattke (2004) - This species keys close to Stictoponera binghamii and to Stictoponera fontana. S. binghamii has much narrower occipital lobes when seen laterally and a lower posteromedian propodeal elevation and lacks the prominent posterolateral crests, as seen in S. gabata. Stictoponera gabata differs from S. fontana in the sharp angles separating the concave posterior cephalic margin from the sides when seen in frontal view. In S. fontana the posterior cephalic margin is relatively straight and the occipital lamella is inconspicuously visible in the background as a pair of small horns. S. gabata has smaller eyes than S. fontana and the anterior margin of the clypeal lamella forms an obtuse and blunt median angle. The subpetiolar process of S. gabata is more triangular than in S. fontana, without an acute posterior angle, and the propodeum has prominent posterolateral crests.

Head densely foveolate in lateral view; occipital lamella convex, relatively broad. Humeral angle well developed, lamellate; pronotum anteroventrally with blunt point. Mesosomal dorsal margin, just posterad of denticles, with declivitous margin extending posterad in lateral view, forming shelf like outline. Propodeal declivity mostly smooth with posteromedian, parallel-sided raised area and prominent posterolateral crests.

Type Material

Holotype worker. Malaysia, Sarawak, Gunung Matang, 20km W Kuching, 800m, 13-v-1994, I. Löbl & D. Burckhardt 2a. Deposited in The Natural History Museum. Paratypes. One worker on same pin as holotype deposited in The Natural History Museum. Two workers in The Natural History Museum, 1w in Instituto de Zoologia Agricola from Malaysia, Sarawak, Gunung Penrissen, 1000m, 23-v-1994, I. Löbl & D. Burckhardt 9a.


The species name is derived from the Latin noun for “dish” or “platter”, gabata (f.), and alludes to the broad posterolateral propodeal lobes.
