Neoscona oaxacensis Keyserling 1864
w US (CA-TX-KS-WA) (+IN & RI?)
You can separate N. arabesca from oaxacensis by the three pairs of dorsal, slanting, dark spots found on arabesca.
A ventral view will separate the two in a heartbeat. See A. packardi compared to N. oaxacensis:
A. packardi has 5 white dorsal marks while N. oaxacensis has more than 5. Also A. packardi has a dark band in the middle of the tibiae while N. oaxacensis' tibiae are light in the center. Compare:
The second white mark on A. packardi is longer than the second white mark on N. oaxacensis. Compare dorsals here:
A. packardi tends to have long white hairs coming off the abdomen. This can be helpful when separating juveniles. The legs of juveniles are also quite different with N. oaxacensis being less banded and having a visible central line on the carapace. Compare:
N. oaxacensis has a row of dots across the front of the abdomen in many cases.
