Strumigenys decollata

Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the Strumigenys decollata-group. This species and Strumigenys praecollata are obviously closely related, but the differently shaped petiole nodes and contrasting cephalic sculptures quickly separate them.

Distribution based on Regional Taxon Lists

Nomenclature

 *  decollata. Strumigenys decollata Mann, 1919: 353, figs. 32, 33 (w.m.) SOLOMON IS. See also: Brown, 1958i: 109; Bolton, 2000: 772.

Description
TL 4.2, HL 1.14, HW 0.69, CI 60, ML 0.66, MI 58, SL 0.60, SI 87, PW 0.42, AL 1.10. Spiniform distal preapical tooth located at about one-third the mandible length from the apicodorsal tooth, the small proximal preapical tooth located at about onethird the mandible length from the base; distal preapical tooth about 5 times longer than proximal tooth. Distance between apicodorsal tooth and distal preapical tooth slightly less than distance between distal and proximal preapical teeth. Anterior clypeal margin deeply concave. Propodeal teeth triangular, broad basally but short; propodeal tooth distinctly larger than proximal preapical tooth on mandible. With petiole in profile the node with a short but distinctly differentiated anterior face; the long, shallowly curved dorsum of the node is about 3.5 X the height of the anterior face. Petiole node in dorsal view about 1.5 X longer than broad (discounting posterior collar). Head without a pair of erect hairs at highest point of vertex, without ground-pilosity. Dorsal surfaces of alitrunk, petiole and first gastral tergite without ground-pilosity. Cephalic dorsum with feeble superficial shagreening; dorsal alitrunk almost smooth, pronotum with faintest vestiges of superficial sculpture.
