Diagnosis. The female of this species can be distinguished from all other congeneric species by having the caudal part of the abdomen extend beyond the spinnerets; the latter are placed at the anterior third of the abdomen. The male of this species can be distinguished from all other congeneric species by having the median apophysis with two dorsal spurs close to each other and by the wide and flattened terminal apophysis.
