Strumigenys naberia Bolton, 2000 |
The type material was found in a soil core taken from a mixed dipterocarp forest and in a litter sample in rainforest.
Identification
Bolton (2000) - A member of the ebbae complex in the Strumigenys koningsbergeri-group. This is the only species of the ebbae-complex to have short spoon-shaped hairs on the upper scrobe margins and leading edges of the scapes. In all others the hairs in these places are simple or at most narrowly elongate-spatulate.
The broad flattened scape described above is shared only with Strumigenys roganas within the ebbae-complex. In both of these SL is only about 4.5 X the maximum width of the scape. In all other species of the complex the scape is much narrower, with SL 6.0-8.0 X the maximum width of the scape.

Description
Worker
Holotype. TL 2.1, HL 0.56, HW 0.48, CI 86, ML 0.22, MI 39, SL 0.28, SI 58, PW 0.29, AL 0.58. With characters of ebbae-complex. Preapical tooth conical, very feebly recurved, almost as long as width of mandible at point where it arises. Inner margin of mandible weakly sinuate proximal of preapical tooth, with a sharp-edged crest, but without a prominent broad translucent lamella. Outer margin of mandible approximately straight in basal half, shallowly convex in apical half. Ventrolateral margin of head without a preocular concavity. Upper scrobe margins broadly divergent posteriorly, eye invisible in full-face view; edge of upper scrobe margin jagged, with a series of small triangular peaks or tubercles and with a small spoon-shaped hair arising from each peak. Scape dorsoventrally flattened and broad, SL only ca 4.5 X the maximum width of the scape. Leading edge of scape broadly convex; hairs on leading edge spoon-shaped, about the same size as those on upper scrobe margin. Posterior vertex of head without a transverse depression. Dorsum of head in profile with short erect hairs along occipital margin, 1-2 on dorsum of occipital lobe and a single pair at highest point of vertex; without erect hairs anterior to this. Pronotum with a single pair of short standing hairs, close to anterodorsal margin. Mesonotu m with a single pair of short erect hairs. Katepisternum smooth, metapleuron and side of propodeum with a smooth patch. Bullae of femoral glands visible but small and inconspicuous on middle and hind legs. Lamella on propodeal declivity with posterior (free) margin straight to shallowly convex. Disc of postpetiole short, smooth. Standing hairs on first gastral tergite simple.
Paratypes. TL 2.1-2.2, HL 0.54-0.59, HW 0.46-0.49, CI 83-85, ML 0.22-0.23, MI 38-41, SL 0.26-0.28, SI 57 (2 measured).
