== Description == thumb Females of this species grow to 10mm, males growing to 9.5mm. The coloration of the prosoma is quite variable in color, though it usually matches that of the opisthosoma. The coloration can vary from tones of tan, to vivid green. Some have a dark line along the median, as the one pictured, and many have a foliate pattern. The legs are also quite variable, and are covered in short spines, which are most notable in males.<ref>{{Cite book |last=Rose |first=Sarah |url=https://www.jstor.org/stable/j.ctv2382dtg |title=Spiders of North America |date=2022 |publisher=Princeton University Press |isbn=978-0-691-17561-4 |volume=154}}</ref>
