  • indagatrix. Strumigenys indagatrix Wheeler, W.M. 1919e: 94 (w.) BORNEO. See also: Brown, 1959g: 86; Bolton, 2000: 793 (misspelled as indigatrix).

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Bolton (2000) - T L 2.4-2.5, HL 0.58-0.66, HW 0.40-0.42, CI 65-70, ML 0.29-0.34, MI 48-53, SL 0.38-0.44, SI 93-102, PW 0.25-0.28, AL 0.60-0.70 (10 measured).

Characters of godeffroyi-complex. Cephalic dorsum with pair of erect hairs closest to midline on occipital margin short stiff and erect, straight to shallowly evenly curved, the apical half not abruptly curved anteriorly. With head in full-face view the dorsolateral margin posterior to the flagellate apicoscrobal hair has a row of 3-4 stiffly projecting hairs. These hairs contrast with the marginal hairs anterior to the flagellate hair as they are more cylindrical (i.e. not spatulate), more elevated and less strongly curved anteriorly. Ground-pilosity on pronotal dorsum conspicuous, arched and somewhat elevated, in profile appearing as a weak pelt. Dorsum of pronotum without flagellate hairs apart from the humeral pair. Entire side of alitrunk densely reticulate-punctate, without smooth patches anywhere. Propodeal declivity with a broad and very conspicuous spongiform lamella, the propodeal teeth only weakly developed (may be vestigial) and entirely buried in the lamella. Dorsal surface of propodeal tooth in profile surmounted by a convex crest or ridge of spongiform tissue. Disc of postpetiole un sculptured or with a few weak short costulae anteriorly; not reticulate-punctate. Basigastral costulae conspicuous but not extending half the length of the tergite.
