Synonyms and other taxonomic changes
Previously placed in the genus Allocosa (by mistake); subsequently referred to as Hogna georgicola by many people up until Brady's 2012 revision transferred it to the genus Tigrosa.
Explanation of Names
Author of name: Charles Walckenaer. First year published: 1837, as Lycosa tarentuloides georgicola.
Size
Body length of females 16-22mm; males 10-17mm.
(1)Identification
(Note: prior to Brady's 2012 Tigrosa revision, many of these T. georgicola were likely misplaced under T. aspersa.)
Venter of abdomen with three central dark stripes originating at the epigastric furrow and converging at base of spinnerets (overall, venter much darker-looking than
T. helluo). Occasionally the dark color covers much of the ventral surface, the melanic form was described as Lycosa (currently Hogna) wallacei and it has yet to be determined whether or not these are truly separate species.
(2) Median stripe on carapace is distinct and extends from the eye region all the way across to the posterior declivity. Sometimes with 3 dark bands on dorsal surfaces of femora III and IV.
