Diagnosis. The only species of the patagonica group with posteromedian margin of the sternite 9 slightly concave and bearing a crescent-shaped sclerite followed by two reniform, stout processes directed caudad, the parameres lacking posteromedial proyection. The female subgenital plate has two slender processes arising from laterodistal margins of gonopore, and the spermarthecae are distinctly pyriform.
