Strumigenys reflexa

Identification
Bolton (2000) - The unique arrangement of clypea1 pilosity is immediately diagnostic. P. reflexa is close to Strumigenys missouriensis but the latter species does not exhibit reflexed hairs along the entire lateral clypeal margins. See also notes under pulchella.

Worker
Bolton (2000) - TL 2.0-2.3, HL 0.52-0.58, HW 0.38-0.42, CI 70-76, ML 0.07-0.09, MI 13-18, SL 0.26-0.30, SI 65-71, PW 0.24-0.26, AL 0.50-0.58 (15 measured).

Anterior clypeal margin broadly convex and its dorsum depressed. Eye with 2-3 ommatidia in the longest row. Curved spoon-shaped hairs on anterior and lateral clypeal margins mostly or entirely reflexed; those on anterior margin curving away from the midline, those on lateral margins curved posterolaterally. Smaller spoon-shaped hairs on clypeal dorsum close to the margins also curved posteriorly or posterolaterally. Most clypeal hairs peripheral, central area of disc hairless. In full-face view dorsolateral margin of head with numerous laterally projecting clavate or apically spoon-shaped hairs that curve dorsally; a slender spatulate straighter hair occurs in the apicoscrobal position. In profile vertex around highest point with suberect to erect short hairs, the apices of which are broadened or spoon-shaped. In addition there is a transverse row of 4 more slender erect hairs just in front of the occipital margin. Pronotal humeral hair long and fine, filiform to flagellate; pronotal dorsum with a pair of erect stiff hairs. Mesonotum with 2-4 pairs of erect hairs that are more or less straight, the anterior pairs longer than the posterior. Pilosity of first gastral tergite erect and slender, apices usually truncated or slightly thickened. Dorsal (outer) surface of hind basitarsus with 1-2 very fine projecting flagellate hairs.
