Strumigenys mayri

The species been recorded once from Bogor Botanical Gardens, Java, where it was probably an introduction. (Bolton 2000)

Identification
Bolton (2000) - See notes under Strumigenys akhtoi. Most of the variation in pilosity and postpetiole disc sculpture noted above was recorded by Brown (1973c). Beside this, separate populations currently assigned to mayri show some changes in width and degree of curvature of the mandibles. These variations may suggest that more than one species resides under the name. For the present I regard all as variations within a single species, but recommend a more detailed analysis when more material is present.

Worker
Bolton (2000) - TL 1.7-1.8, HL 0.52-0.60, HW 0.37-0.41, CI 68-73, ML 0.25-0.30, MI 47-53, SL 0.32-0.38, SI 85-93, PW 0.23-0.25, AL 0.50-0.56 (25 measured).

Characters of the mayri-complex. Preapical tooth spiniform, its length usually slightly greater than maximum width of mandible. Apicoscrobal hair present, without similar long projecting hairs on upper scrobe margin anterior to it. Cephalic dorsum with 4-6 erect simple hairs along the occipital margin and a similar pair at level of highest point of vertex. With head in full-face view most or all of the eye visible, the upper scrobe margin above the eye not so broadly expanded as to obscure most of the eye. Preocular notch present, variable in width and depth between populations but always disinct; ventral surface of head with preocular transverse impression short, may be shallow but usually conspicuous. Pronotal humeral hair usually flagellate, apparently simple and sinuous in some but this may the result of damage. Pronotum otherwise without erect hairs; mesonotum with one pair of erect simple to flagellate hairs. Dorsal alitrunk evenly reticulate-punctate. Dorsal surfaces of waist segments and gastral tergites with hairs that are fine and simple to flagellate. Pleurae and side of propodeum mostly to entirely smooth. Propodeum armed with a pair of short spines, length of spine equal to or slightly greater than distance separating their bases but less than dorsal width of petiole node. Dorsal (outer) surface of hind basitarsus without long fine erect hairs. Petiole in profile with anterior face of node not markedly less than length of dorsum, in dorsal view petiole node broader than long. Disc of postpetiole varying from finely and densely reticulate-punctate to almost entirely smooth.
