Pseudonascus paulliniae shows little variation in color and pattern in central Rondônia, but some individuals have more broadly rounded wings than others (male mean FW length = 22.3 mm [20.7-23.4, n = 10]; female mean FW length = 24.5 mm [21.6-26.2, n = 3]). The genitalia ( Fig. 117 , 124 ) were described above in the generic description. Those of both sexes from Rondônia do not differ from those of individuals examined from Central America .

Pseudonascus paulliniae is common at Cacaulândia, with records for most of the year (none in January and March; Fig. 130 ). This species ranges from southern Mexico to Bolivia and Brazil ( Hoffmann 1941, Evans 1952, de la Maza and de la Maza 1985, Warren 2000).
