Th e two species can be easily distinguished by male genital morphology: the valva of <i>fraudulentella</i> is distinct in possessing a more slender, greatly elongated saccular lobe which surpasses the apex of the cucullar lobe by nearly half its length, compared to being only slightly longer than the cucullar lobe in <i>nearctica</i> (Fig. 7). The two bristles comprising the frenulum of female <i>P</i>. <i>nearctica</i> appear superficially to be fused as one. With slight pressure, however, these can be separated. Whether this peculiar condition of the frenulum is typical for all <i>Pelecystola</i> is not known.
