Strumigenys anchis

Nothing is known about the biology of .

Identification
Bolton (2000) - A member of the Strumigenys emmae-group. The combination of two large preapical teeth and a deep concave impression in the anteroventral margin of the head in front of the eye immediately diagnoses this species. Strumigenys radix also has a fairly well developed distal preapical tooth, but this species is smaller, has longer, more slender scapes, lacks the impression in the anteroventral margin of the head and possesses an apicoscrobal hair.

HOLOTYPE. TL 2.1, HL 0.57, HW 0.47, CI 82, ML 0.20, MI 35, SL 0.26, SI 55, PW 0.28, AL 0.54. Exposed length of fully closed mandible less than width of anterior clypeal margin. Preapical dentition of mandible consisting of a long-conical proximal preapical tooth and a flattened shorter, broader distal preapical tooth; apex of distal tooth truncated or bevelled, obviously not conical. Inner margin of mandible proximal of the long-conical proximal preapical tooth with a narrow convex cuticular lamella. Anteroventral margin of head deeply concave in front of eye. Antenna with 4 segments; second funicular segment distinctly longer than broad. Cephalic dorsum with orbicular hairs; upper scrobe margin fringed with similar or broadly spoon-shaped hairs; without an apicoscrobal hair. Occipital margin of head without short erect hairs. Eye relatively large, with 5 ommatidia in the longest row and more than 15 ommatidia in total. Leading edge of scape flattened and evenly convex, not forming an obtuse angle at about the midlength. Pronotal humeral hair short and upcurved, spatulate to remiform. Ground pilosity of pronotal dorsum as head but the hairs tending to be smaller and more widely spaced. Mesonotum without erect hairs. Promesonotal dorsum reticulate-punctate. Disc of postpetiole finely shagreenate at least in part. First gastral tergite with short suberect to erect hairs that are spatulate to remiform. Basigastral costulae at least equal in length to postpetiole disc.
