Diagnosis.

Differing from other species in the group based on the shape of the internal male genitalia (Fig. 11C-I View Figure 11 ). In dorsal view, the dorsal valves form two translucent lobes that are nearly equal in length to the ventral valves and are pointed at their apices. The ventral valves are opaque cylindrical protrusions that are pointed at their apices. In lateral view, the dorsal valves are nearly equal in length to the ventral valves, twist caudally and taper to their apices. In caudal view, the dorsal valves extend above the ventral valves (Fig. 11G View Figure 11 ). This species can most easily be separated from G. pusillus by having longer dorsal and more translucent dorsal valves and from G. wadeorum by the more angled apices and the slight caudal twist in the dorsal valves. G. georgiaensis can also be distinguished from these species by their separate geographic distributions (Fig. 12 View Figure 12 ).
