Identification

Some anatomic details of female Atlanticus pachymerus:

pronotum subgenital plate

Badly confused in literature with A. testaceus, but more southern in distribution; differing in males having shorter wings, shape of subgenital plate of females, and in having longer and thus apparently more slender legs.

Range

Ozark/Ouachita region of eastern Oklahoma, Missouri and Arkansas eastward to North and South Carolina, also apparently west into se. Oklhoma and ne. Texas.

Remarks

Badly confused in literature with A. testaceus, differing in males having shorter wings, shape of subgenital plate of females, and in having longer and thus apparently more slender legs.
