Nomenclature

 *  ignota. Strumigenys ignota Bolton, 2000: 844, figs. 445, 505 (w.) BORNEO.

Worker
Holotype. TL 2.8, HL 0.81, HW 0.70, CI 86, ML 0.34, MI 42, SL 0.43, SI 61, PW 0.34, AL 0.72. With characters of koningsbergeri-complex. Preocular concavity forms an extensive shallow depression on ventral surface of head. Upper scrobe margins not constricted above eye, only outer arc of eye visible in full-face view. Edge of upper scrobe margin with a row of 5-6 broad-based small triangular teeth, margin with a distinctly jagged appearance (more strongly developed in larger than in smaller workers). Depression across posterior vertex of head broad but very shallow. Pronotum without a pair of short standing hairs close to anterodorsal margin. Pronotal humeral hair elongate, stiffly straight and simple. A single erect pair of hairs on mesonotum. Katepisternum mostly smooth, metapleuron usually with a small smooth patch. Bullae of femoral glands present on middle and hind legs, oval to long-ovate, usually conspicuous. Lamella on propodeal declivity conspicuous. Standing hairs on first gastral tergite simple or weakly expanded and flattened toward the apex.

Paratype. TL 2.9, HL 0.83, HW 0.71, CI 86, ML 0.35, MI 42, SL 0.42, SI 59, PW 0.35, AL 0.76.

Dimensions of non-paratypic workers average smaller. HL 0.68-0.75, HW 0.58-0.64, CI 85-87, ML 0.30-0.33, MI 43-44, SL 0.37-0.39, SI 60-64 (4 measured).

Type Material
Holotype worker, Malaysia: Sarawak, Santubong, Kuching, v.1994 (Lobl & Burckhardt). Paratype. 1 worker with same data as holotype.
