Previously genus Hogna; was transferred to the new genus Tigrosa in 2012 by Allen Brady.

Body length (excluding legs) of adults ranges from 10 - 18 millimeters.(1)
This is the smallest species in the genus; the venter of the female is all pale yellow, except for a dark 'V'-shaped marking in center of the sternum and a black spot around the epigynum; venter of adult male is all pale. Carapace has two yellow dashes flanking the median stripe in the cephalic region.(1) This species is closely related to T. helluo, but is smaller in size and lighter in color.(2)

Adult female:

Adult male:

Along the Atlantic coast from Delaware south to Big Pine Key, Florida, and westward from southern Ohio to the southern tip of Texas.(1)
Seems to prefer a drier, more sandy habitat than some of the other Tigrosa species. Allen Brady (2012) notes that many of the specimens he examined for his revision were collected in pitfall traps in cotton fields and Bermuda grass.(1)
"I've kept two females in captivity and this species doesn't appear to be the burrowing type; it seems to prefer wandering about instead." ~ pers. comm. Mandy Howe
