Keys to the genera of Dolichoderinae in or possible in the Southeastern United States
(Keys adapted from Creighton 1950; Bolton 1994)

1
Petiole is reduced to a simple, flattened strip when seen in profile, never with a standing scale or node; the length of the propodeal dorsum is much shorter than the propodeal declivity; the first gastral segment projects over the petiole, and the petiole not usually visible from above when thorax and gaster are in the same plane (fig. 1)
 

Petiole has a node or scale when seen in profile, node may be high and erect, or lower and inclined forward, but it is always present and noticeable; gaster may or may not project over the petiole (fig. 2)

2(1)
Only 4 gastral tergites visible in dorsal view, the fifth tergite is reflexed below the the fourth and is visible in ventral view, anal and associated orifices are directed ventrally fig. 3); no erect hairs present on dorsum of mesosoma (fig. 4); concolorous dark brown to blackish brown or with gaster, legs, and antennae also brownish colored(fig. 5)
 
Five gastral tergites visible in dorsal view, anal and associated orifices are directed apically (fig. 6); erect hairs present on dorsum of mesosoma (fig. 7); body dark brownish black to black except for tarsi and funicular segments yellowish white (fig. 8)
3(1)
 
The integument thin, weakly sculptured, but can be dense; no foveolate punctures on head; no tooth-like prominence on hypostoma, propodeal declivity not concave (fig. 10)
4(3)
In profile, propodeum has a single raised tooth or spine extending from the angle between the dorsum and the declivity (fig. 11)
 
In profile, propodeum may be angular, but never extending into a tooth or spine (fig.12 )
5(4)
The anterior clypeal margin has 2-12 ventrally curved setae that are about the same length as the closed mandibles (fig. 13); basal margin of the mandible unarmed; the first gastral segment projects over the petiole (fig. 14)
 
The anterior clypeal margin with 2-6 setae that are much shorter than the closed mandibles (fig. 15); basal margin of the mandible has denticles close to the basal angle; the first segment of the gaster is vertical in orientation and does not project over the petiole (fig. 16)
