Genus Barronopsis

7 species, 5 in our range.(1)

Barronopsis barrowsi

Barronopsis floridensis

Barronopsis jeffersi

Barronopsis stephaniae

One way Barronopsis can be separated from Agelenopsis is by the proportions of the posterior lateral spinnerets. In Barronopsis the proportion of the distal segment to the basal segment is 1:1, whereas in Agelenopsis it's 2:1 (distal segments twice as long as the basal). It works sometimes, but usually it's too hard to tell the exact lengths of them in photos. Especially with hairs in the way and everything. A caveat is that some Agelenopsis species such as A. aperta appear to have shorter distal segments. Example photos:

Barronopsis also tends to have less complete dark stripes on the carapace, and leg patterning with noticeable narrow light bands. However, this distinction can be tricky to make.

Barronopsis barrowsi — USA, Cuba, Hispaniola(1); FL, southeastern GA

Barronopsis floridensis — USA, Bahama Is.(1); peninsular FL

Barronopsis jeffersi — USA, Cuba(1); northern FL, southern GA. Specimens also found in DC & MD, primarily in synanthropic locations.(2)

Barronopsis stephaniae — USA; SC, GA, north FL

Barronopsis texana — USA; TX, LA, MS, AL, FL, GA, SC, NC, TN(2). Possibly also VA.

B. jeffersi and B. texana are often found in webs on manmade structures.

B. floridensis, B. jeffersi, and B. texana usually have webs in locations above the ground.

B. barrowsi and B. stephaniae generally build webs on the ground.(2)
