Notes: The male terminalia are in general similar to N . rondanica Quate & Alexander, 2000 ( Brazil , Rondônia ) and N . stenhygros Quate & Alexander, 2000 ( Brazil , Pará ) ( Quate &Alexander 2000 ), but both those species lack extended abdominal tergites and ornamental setulae. The presence of clusters of setae in the female genital cavity is also not unique to the new species, similar structures having been mentioned in N .
