Variable, but typically very dark reddish-brown to nearly black, mandibles, append ages, and the tip of the gaster paler (brownish-yellow to yellowish-brown); head and alitrunk very finely but densely punctate, surface moderately dull; pubescence very short. The only species in our area; see generic diag¬≠nosis.
Most Ohio references incorrectly list it as a subspecies of the European P. coarctata.
They form small colonies “seldom more than 40 or 50 workers with 5 to 15 pupae during brood rearing” (Amstutz, 1943). But these small colonies can be abundant in the soil (Headley, 1952). Cocoons are oblong and yellow-ish in color.
A series of four normal males, two workers, and three ergatomorphic males collected by C. H. Kennedy, Aug. 23, 1930 on Pelee Island, Ontario, Canada (DMNH col In., Kennedy #3163, which does not correspond to his notes) were examined. Kennedy had referred to these specimens as “antero-posterior gynandromorphs!” Basically they have the head of a male with a worker thorax and abdomen. One specimen appears to have a completely typical worker abdomen while the other two have greatly reduced male genitalia.
In Taylor ( 1967:8) it is stated for the genus Ponera that male “ergatoids are apparently not developed.” Ergatoid males are known for Hypoponera [H. gleadowi (as ergatandria) and H. opaciceps in our area; see Smith & Haug, 1931 ], so the preceding constitutes the first known record of ergatoid, or worker-like, males for the genus Ponera.
