Strumigenys comis

Identification
Bolton (2000) - S. comis combines moderately expanded upper scrobe margins with a lack of alitrunk sculpture, lack of projecting hairs on the dorsolateral margins of the head but presence of such at the pronotal humeri. It separates from other taxa in the group as Strumigenys kompsomala, Strumigenys rugithorax and Strumigenys villiersi have long flagellate hairs projecting from the head dorsolaterally, freely projecting hairs on the tibiae and strong sculpture on the dorsal alitrunk. Strumigenys splendens has the preocular carinae fully exposed, the pronotum without margination and broadly transversely convex, and the humeri without hairs. In Strumigenys abditivata and Strumigenys dentinasis the preocular carinae are completely concealed in full-face view and each upper scrobe margin has two large fenestrae posterior to the small fenestra above the antennal insertion.

Worker
Bolton (2000) - TL 2.3-2.4, HL 0.66-0.68, HW 0.49-0.50, CI 74-76, ML 0.05-0.06, MI 7-9, SL 0.24-0.30, SI 55-60, PW 0.27-0.28, AL 0.62-0.66 (3 measured). With head in full-face view the extreme anterior portion of the preocular carina is visible, through the impression between clypeus and frontal lobe. Frontal lobes and frontal carinae broadly expanded, with a continuous outer margin that is convex, not sinuate. A small fenestra present over antennal insertion and another close behind it in the upper scrobe margin. Mandibles, clypeus and vertex unsculptured, frontal carinae shagreenate. Dorsolateral margins of head without freely projecting hairs of any form; cephalic dorsum without standing hairs. Pronotal dorsum transversely flat, marginate dorsolaterally, with a simple curved humeral hair. Mesonotum with 2 pairs of standing hairs. Alitrunk unsculptured. Short simple standing hairs present on waist segments and all over surface of first gastral tergite. Middle and hind tibiae without freely projecting hairs on their dorsal (outer) surfaces. With petiole in profile the dorsal length of the node only slightly greater than the height of the anterior face.
