Known from the type series, a collection taken from a rotten log in a rainforest.
Identification
Bolton (2000) - A member of the Strumigenys capitata-group. Apart from the characters listed above the alitrunk of serradens is more finely sculptured, with the dense reticulate-punctate component emphasised and the rugular component very much diminished when compared to Strumigenys serraformis, where the rugular component is conspicuous.

Description
Worker
Holotype. TL 4.0, HL 0.86, HW 0.72, CI 84, ML 0.28, MI 33, SL 0.46, SI 64, PW 0.56, AL 1.16. Answering the description of the closely related serraformis but differing as follows.
1 Vertex densely sharply reticulate-punctate and with fine rugulose sculpture toward the sides (rugulae not equally dense on centre of vertex as in serraformis).
2 Mesonotum with a single pair of standing hairs (caution, available specimens may be abraded).
3 Petiole in profile without a differentiated anterior face to the node.
4 Disc of postpetiole covered everywhere with uniformly dense sharply defined reticulate-punctate sculpture.
5 Basigastral costulae at least as long as the postpetiole disc.
6 Dorsum of first gastral tergite smooth and shining behind level of basigastral costulae.
7 First gastral sternite smooth everywhere except for hair pits.
Paratypes. TL 3.9-4.2, HL 0.84-0.86, HW 0.72-0.76, CI 84-88, ML 0.28-0.30, MI 33-34, SL 0.46-0.48, SI 62-65, PW 0.54-0.58, AL 1.10-1.24 (5 measured). All paratypes show signs of abrasion, with loss of hairs here and there.
