Worker
Holotype. TL 2.0, HL 0.51, HW 0.34, CI 67, ML 0.07, MI 14, SL 0.27, SI 79, PW 0.24, AL 0.52. Answering the description given for Strumigenys dictynna, to which it is closely related; the two are separated by the following distinguishing characters.

S. agnosta: Spatulate hairs on disc of clypeus fine and indistinct. Occipital lobe without a laterally projecting flagellate hair in full-face view. Cephalic dorsum close to occipital margin with a single pair of fine erect hairs that are situated close to the midline. Hairs on first gastral tergite restricted to a basal and an apical transverse row, the central band of the sclerite hairless. Dorsal length of petiolar peduncle about equal to the height of the anterior face of the node in profile.

S. dictynna: Spatulate hairs on disc of clypeus broad and conspicuous. Occipital lobe with a laterally proj ecting flagellate hair in full-face view. Cephalic dorsum close to occipital margin with a pair of erect hairs close to the midline, and a second pair close to the occipital corners that are directed dorsolaterally. Hairs on first gastral tergite distributed over the sclerite, without a broad hairless central band. Dorsal length of petiolar peduncle greater than height of the anterior face of the node in profile.

Paratypes. TL 1.9-2.0, HL 0.47-0.51, HW 0.33-0.34, CI 66-72, ML 0.07, MI 14-16, SL 0.25-0.27, SI 74-79, PW 0.22-0.25, AL 0.50-0.52 (7 measured).
