Strumigenys natynion

A specimen of this species was collected in a montane rainforest litter-sample.

Identification
Bolton (2000) - A member of the caniophanes complex in the Strumigenys caniophanes-group. See notes under Strumigenys mododonta. Representation of this species is a small number of isolated and varying individuals, no two of which are identical. All appear to belong to a single plastic species but it is distinctly possible that more than one real species is concealed here. Resolution of the problem must await the discovery of more, and larger, samples. Because of this I have restricted the type-series to a single nest sample.

Variation in the material available includes density and length of erect pilosity on head, alitrunk and gaster; presence or absence of small erect hairs on ventral surface of head; length and thickness of propodeal teeth.

Distribution based on Regional Taxon Lists

Worker
Holotype. TL 3.5, HL 0.94, HW 0.70, CI 74, ML 0.44, MI 47, SL 0.50, SI 71, PW 0.41, AL 0.98. Mandible with a small preapical tooth. Dorsolateral margin of head in full-face view with 5 or more freely laterally projecting filiform hairs; occipital lobe margin also with a number of shorter hairs that are directed dorsally. Cephalic dorsum with erect fine hairs in a transverse row across occipital margin and usually with a single more anterior pair, close to highest point of vertex. Dorsum of head finely and densely punctate-rugulose. Apical funicular segment moderately tapered basally. Promesonotal dorsum, side of pronotum, pleurae and side of propodeum everywhere densely punctate to reticulate-punctate. Pronotal humeral hair long and fine. Dorsal alitrunk with numerous erect fine simple hairs; waist segments and first gastral tergite with numerous similar hairs. Dorsal and ventral surfaces of hind femur with suberectlerect hairs; dorsal (outer) surfaces of hind tibia and basitarsus each with long erect freely projecting hairs. Petiole in profile claviform, in dorsal view much longer than broad.
