Strumigenys sublaminata

Known from a few litter-samples and a rotten wood collection in rainforest and wet forest habiats. Heterick & Kitching (2022) collected this species in the canopy of a lowland dipterocarp forest in Brunei.

Identification
Bolton (2000) - A member of the signeae complex in the Strumigenys godeffroyi-group. A widely distributed but apparently uncommon species. All the examined collections consist of only one or two individuals. See notes under Strumigenys signeae.

Nomenclature

 *  sublaminata. Strumigenys sublaminata Brown, 1959g: 84 (w.q.) BORNEO. See also: Bolton, 2000: 828.

Worker
Bolton (2000) - TL 2.0-2.4, HL 0.54-0.70, HW 0.42-0.52, CI 73-79, ML 0.21-0.26, MI 35-39, SL 0.26-0.34, SI 62-69, PW 0.26-0.30, AL 0.56-0.68 (8 measured).

Characters of signeae-complex. Apicoscrobal hair short and stiff, remiform to weakly clavate; margin anterior to this hair (upper scrobe margin) with a series of anteriorly curved small spoon-shaped hairs; margin posterior to apicoscrobal hair without projecting hairs. Cephalic dorsum with a transverse row of 4-6 erect hairs at occipital margin; without standing hairs anterior to this. Pronotal humeral hair spatulate to weakly remiform, pronotum otherwise without standing hairs. Mesonotum with an anteriorly situated pair of erect spatulate to weakly remiform hairs; often with 1-2 other, much shorter pairs posterior to this. Entire dorsal alitrunk densely reticulate-punctate. Side of alitrunk with pleurae and propodeum mostly to entirely smooth. Petiole node in dorsal view reticulate-punctate. In profile lateral spongiform lobe of petiole small, confined to posterior portion of node. Disc of postpetiole unsculptured, smooth. First gastral tergite with spatulate to remiform standing hairs. Basigastral costulae very short.

Queen
Brown (1959) - The dealate female paratype, taken with the holotype, has a very high-bulking thorax; mesonotum densely and finely punctulate, without rugulation or median furrow, but with about 23 erect spatulate hairs. Petiolar node broader than long; otherwise, only the usual caste differences from the worker. TL 2.8, HL 0.65, ML 0.24, WL 0.72 mm.; C 77, MI 37.

Type Material
Bolton (2000) - Holotype worker, paratype workers and queen, MALAYSIA: Sarawak, Gn. Penrissen, 4000 ft (E. Mjoberg) [examined].
