Identification

Bolton (2000) - A member of the caniophanes complex in the Strumigenys caniophanes-group. This large, slender-headed species is one of three in the group (Strumigenys sardella, Strumigenys tadynastes, tomodonta) that lack long erect hairs on the hind tibiae and basitarsi. All except tomodonta have freely laterally projecting hairs on the dorsolateral margin of the head. Also, sardella is easily distinguished by the presence of a cuticular lamella on the inner margin of the mandible. Apart from the characters given in the key, tadynastes has weakly transversely costulate fore coxae (punctate in tomodonta) and has the petiole node in profile with an anterior face that is clearly differentiated from both the peduncle and the dorsal surface of the node (claviform in tomodonta).

Description

Worker

Holotype. TL 3.9, HL 1.06, HW 0.68, CI 64, ML 0.54, MI 51, SL 0.58, SI 85, PW 0.43, AL 1.05. Mandible in full-face view with a small triangular preapical tooth. Dorsolateral margin of head in full-face view with short fine strongly curved ground pilosity but without freely laterally projecting long hairs. Cephalic dorsum with fine short ground-pilosity that is moderately dense, curved and feebly elevated, but without standing long hairs anywhere. Dorsum of head finely and densely reticulate-rugulose, the reticulae very small. Entire alitrunk, dorsally and laterally, sculptured with relatively large separated punctures; in places on the pronotum the punctures may be confluent. Pronotal humeral hair quite short (about one-third of SL or less), soft and simple, curved posteriorly (may be an artifact). Dorsal alitrunk without long erect or flagellate hairs. First gastral tergite with fine simple curved hairs and one or two longer subflagellate hairs. Dorsal surfaces of femora, tibiae and basitarsi with short curved pilosity that is simple and mostly decumbent, without long erect freely projecting filiform or flagellate hairs. Propodeal teeth narrowly triangular and acute. Petiole node in dorsal view longer than broad; lateral spongiform lobes of petiole very short, restricted to posterolateral angles. Dorsum of petiole and disc of postpetiole densely sculptured. Petiole in profile claviform, the node with a long, low shallowly convex dorsum.
