Spiracme

Spiracme is a genus of crab spiders erected by Anton Menge in 1876 to contain S. striata, transferred from Xysticus.^[2] The exact relationship of these spiders and their closest relatives has been long debated, and many included species have been transferred to and from similar genera, namely Xysticus and Ozyptila.^[1] Most recently, Rainer Breitling conducted a DNA barcoding study in 2019 and grouped similar species based on the results:^[3]
