Wright & Gilligan in fasc. 9.5 list only 3 species in the P. agassizii group. The other two bolanderana and laticurva do not closely resemble agassizii. To me my photo looks most like fig. 1d on plate A which is a female. Mine looks to be a male. Wright & Gilligan says that the females have a white costal mark before mid-wing,and males are without this white mark. Also note the unbroken sub costal apical white band along with the white serpentine band, also unbroken.
