Thiodina Simon, 1900

Type species. Attus elegans Nicolet, 1849 = Thiodina nicoleti Roewer, 1951 .

Diagnosis. Thiodina males resemble those of Arachnomura, Atomosphyrus, Cyllodania and Hyetussa by having spine-like setae in a scattered pattern on the anterior surface of the male chelicera, but differ from those thiodinine genera (except Arachnomura) for including species with a strong pattern of dark/clear longitudinal stripes on the abdomen of both sexes. Thiodina differs from Arachnomura by having a shorter and wider embolus.
