Identification

Bolton (2000) - A member of the lyroessa complex in the Strumigenys lyroessa-group. Within the lyroessa-complex three species are characterised by their lack of a pronotal humeral hair and a lack of standing hairs on the dorsolateral margins of the mesonotum: Strumigenys aechme, Strumigenys lyroessa and Strumigenys tantilla. Of the three aechme is recognised by its lack of an apicoscrobal hair and its distinctive gastral pilosity.

Description

Worker

Holotype. TL 2.4, HL 0.74, HW 0.57, CI 77, ML 0.21, MI 28, SL 0.29, SI 51, PW 0.33, AL 0.69. Characters of lyroessa-complex. Upper scrobe margin and leading edge of scape with small curved spoon-shaped hairs. Apicoscrobal hair absent; dorsolateral margin of occipital lobe without projecting hairs (minute ground-pilosity may occur). Cephalic dorsum without standing hairs except for a very short hair at apex of occipital lobe. Pronotal humeral hair absent and dorsal alitrunk entirely lacking standing hairs. Posterior half of first gastral tergite with a few suberect stiff hairs that are either elongate-spatulate or weakly remiform. Surface of first gastral tergite everywhere with ground-pilosity of conspicuous short but quite broad spatulate hairs that are reclinate to appressed. These hairs are distinctly shorter than the suberect main pilosity and are quite widely spaced, the distances between their bases being slightly greater than the lengths of the hairs themselves.

Paratypes. TL 2.3-2.5, HL 0.71-0.76, HW 0.53-0.58, CI 74-77, ML 0.20-0.22, MI 28-30, SL 0.28-0.29, SI 50-53, PW 0.31-0.35, AL 0.66-0.73 (4 measured).
