In females, seta h2is shorter, reaching only halfway to terminal appendages (reaches well beyond appendages in  N. tyranni); terminal cleft is relatively long and more slender than in  N. tyranni(length of the terminal cleft approximately four and a half times the width at level of seta h 2in the new species, but only about twice that width in  N. tyranni); three to four pairs of large lacunae on posterior area of anterior hysteronotal shield (those lacunae absent in  N. tyranni).  Figure 3.  Nycteridocaulus guaratubensis sp. nov., female: dorsal (A) and ventral (B) views.  Male( Figures 1, 2A–D) ( holotype, measurements for five paratypesin parentheses).
