Diagnosis

Diameter 1.68–1.75 mm, 46–51 podous rings. Gonopods: lateral incision of coxa (li) broad, shallow, with rounded bottom, basally delimited by triangular tooth; apical palette (pa) rounded, not longer than broad; telomere describing a 360° curve in three dimensions; mesal-posterior lamella of telomere (mpl) low; anterior margin of telomere without a triangular tooth; telomere tip with coarsely laciniate margins, internal surface smooth.

Etymology

The name is a Greek noun, here in apposition, composed of stereo-, which refers to the threedimensionality of the curvature of the telomere, and sathe, literally meaning “penis”, here referring to the telomere.
