No, there isn't, but there are atlases (Desai's Freesurfer-based segmentation atlases and the Talairach daemon) that contain various superior and temporal gyrus areas, banks of sts and related Brodmann areas too. One could compose an edge region between if needed. There are two other atlases available elsewhere you can download and add to AFNI.

Brainvisa Sulci atlas
http://www.lnao.fr/spip.php?article229

ICBM Sulcal probability atlases
http://www.loni.usc.edu/ICBM/Downloads/Downloads_ICBMprobabilistic.shtml

For the first one, download and create a script like this one:

# turn lnao's probability maps into a maximum probability map atlas

cat anat_landmark_atlas.csv | awk -F, '{printf " %s\n", $8}' >labels.txt
count -digits 1 1 147 > count.1D
# manually edit labels.txt to have a column of consecutive numbers from 1 to 147

3dcalc -a anat_landmark_atlas.nii.gz'[0]' -expr 0 -prefix zero
3dTcat -prefix sulci zero+tlrc. anat_landmark_atlas.nii.gz
# find structure that gives maximum probability and remove extremely low values
3dTstat -argmax -prefix sulci_mpm -overwrite sulci+tlrc'<0.01..2>'
count -digits 1 -column 1 147 > count.1D
# edit labels.txt
@Atlasize -lab_file labels.txt 1 0 -dset sulci_mpm+tlrc.

For the second atlas from ICBM, the script is similar, but the atlas has special difficulties because the Analyze format it uses doesn't have correct spatial coordinates, so the final result is not aligned to any of our templates. If you are interested, we (you or I) can look at this more.

3dcalc -a vertical_ramus_sylvian_L.hdr -expr 0 -prefix zero
3dTcat -prefix sulci zero+orig. *.hdr
3drefit -view tlrc -space MNI sulci+orig.
@Align_Centers -base ~/abin/MNI152_T1_2009c+tlrc. -dset sulci+tlrc. -no_cp
3dTstat -argmax -prefix sulci_mpm sulci+tlrc
count -digits 1 -column 1 40 > count.1D
ls *.hdr | sed 's/.hdr//g' > labellist.txt
# manually edit labellist.txt to have a first column of numbers 1-40
@Atlasize -lab_file labellist.txt 1 0 -dset sulci_mpm+tlrc.

Compare these regions with the other AFNI atlases in your afni directory.
