Nothing is known about the biology of Strumigenys hastur.
Identification
Bolton (2000) - A member of the smythiesii complex in the Strumigenys godeffroyi-group. This is one of only two species in the complex to have freely laterally projecting stiff hairs present on the upper scrobe margin anterior to the apicoscrobal hair (the other is Strumigenys liukueiensis). This, coupled with its small size and reduced sculpture, isolates the species within the complex. See notes under Strumigenys lichiaensis.

Description
Worker
Holotype. TL 1.9, HL 0.51, HW 0.38, CI 75, ML 0.20, MI 39, SL 0.26, SI 68, PW 0.22, AL 0.51. Characters of smythiesii-complex. Apicoscrobal hair stiff and simple; the upper scrobe margin anterior to this with 2-3 freely projecting simple stiff hairs, at least with one at about level of eye and one closer to frontal lobes. Cephalic dorsum with a broad smooth patch that covers the most elevated area of the vertex and extends posteriorly to the occipital margin; surface weakly reticulate-punctate on each side of this smooth patch and anterior to it. Cephalic dorsum with short straight hairs, erect or inclined anteriorly, present from about level of eye to occipital margin. Pronotal humeral hair flagellate. Entire dorsum of alitrunk smooth, without trace of sculpture. Pronotal dorsum and mesonotum each with a single pair of erect sub flagellate hairs. Dorsum of petiole node and disc of postpetiole smooth. First gastral tergite with a transverse row of 4 standing hairs near base and another row near apex; without standing hairs between these two rows. Basigastral costulae traverse limbus but extend for only a very short distance onto tergite proper.
