At first it was thought these specimens represented a variant of P. lobipes; however, certain morphological features could also be attibuted to those of P binghami. The type material of the two species is not available. In females of P. mixtus, caudal rami setae are narrow in P. lobipes, though urosomite 2 lacks the dorsal spinule row. The P5 is similar to binghami, but exopodal segment 1 distomedial knob is reduced whereas in lobipes it is repkaced by a notch. In males, the P5 left exopodal segment 2 is glove-like and ovate as in binghami, while the left basis resembles that of lobipes, though medial process is bent at midlength rather than near the apex as in lobipes and binghami. Finally, the right coxa possesses a small medial protrusion, which is larger in binghami but is absent in lobipes (See Table 2, compare with P. lobipes and binghami)
