Diagnosis

Males of Idiops sertania sp. nov. differ from those of other Neotropical species by having the robust embolus with a wide basal half, strongly curved dorsally, with torsion at the apical end and a conspicuous embolar lamella close to the opening of the sperm duct ( Figs 32D–F View Fig , 33E–F View Fig ) and by having the palpal tibia elongated (similar to I. germaini ) ( Fig. 32C View Fig ). Differs from I. germaini by having large spines distributed along the margin of the retrolateral depression ( Figs 32C View Fig , 33D View Fig ) and by the robust tibial apophysis ( Fig. 32H View Fig ).

Etymology

The term ʻsertaniaʼ, referenced in the specific epithet, is a tribute to the ʻsertãoʼ of Brazil, a large region of the country where these spiders occur. The term sertão refers to culturally diverse regions, far from the coast and large cities, and generally associated with rural regions with little human occupation.
