Fig. 11

Diagnosis

Diameter 1.58–1.77 mm, 50–52 podous rings. Gonopods: lateral incision of coxa (li) deep, basally delimited by triangular tooth; apical palette (pa) rounded, not longer than broad; telomere bending 90° distal after basal lamella, tip of telomere curving laterad (towards coxa); mesal-posterior lamella of telomere (mpl) low; anterior margin of telomere without a triangular tooth; telomere tip densely microspiculate.

Etymology

The name refers to the microspiculate (denticulate) telomeral tip (Frederiksen 2013).
