Diagnosis

The male of Idiops mocambo sp. nov. differs from other Neotropical species by anterior region of the carapace in a pointed shape ( Fig. 23A View Fig ), sternum with distinct black edges ( Fig. 23B View Fig ) and by the apical branch of the tibial apophysis in rectangular shape ( Fig. 23G–H View Fig ).

Etymology

The specific epithet refers to the location where the holotype specimen was collected.
