Identification

Bolton (2000) - A member of the lyroessa complex in the Strumigenys lyroessa-group. Three species within the lyroessa-complex lack a pronotal humeral hair and lack standing hairs on the dorsolateral margins of the mesonotum (Strumigenys aechme, Strumigenys lyroessa, Strumigenys tantilla). Characters separating them are mentioned under the first two named.

Description

Worker

Holotype. TL 2.7, HL 0.77, HW 0.61, CI 79, ML 0.23, MI 30, SL 0.31, SI 51, PW 0.37, AL 0.74. Characters of lyroessa-complex. Upper scrobe margin and leading edge of scape with similar-sized small curved spoon-shaped hairs. Apicoscrobal hair short and stiff, inconspicuous, broadening apically; posterior to this the dorsolateral margin without projecting hairs. Cephalic dorsum without standing hairs except for one or two very short hairs at apex of occipital lobe. Pronotal humeral hair absent; dorsal alitrunk entirely lacking standing hairs. First gastral tergite with stiff standing hairs that are conspicuously spatulate, especially on the posterior half. Surface of first gastral tergite otherwise with inconspicuous, widely scattered minute appressed pubescence that is very narrowly spatulate. Propodeal declivity with lamella immediately below the tooth less than half the lamella’s maximum width.

Paratypes. TL 2.5-2.7, HL 0.73-0.78, HW 0.56-0.61, CI 76-79, ML 0.21-0.23, MI 27-30, SL 0.29-0.31, SI 49-52, PW 0.33-0.37, AL 0.68-0.75 (5 measured).
