P. erika vs. ( P. kasyi )

External characters (33–42; 47–49). On forewing antemedial line irregularly zigzagged with acute tips, middle tooth longer than other teeth; subterminal line interrupted, serrate with weakly pronounced triangular spikes (antemedial line clearly zigzagged with rounded tips, all three teeth of similar length; subterminal line serrate with well-pronounced triangular spikes).

Male genitalia (figs 86–97; 101–102). Sacculus oval to rectangular; one or more spines on the dorsal tip of sacculus elongated and slightly stronger than other spines (sacculus small, triangular; all spines on sacculus small, those on ventral tip only marginally longer and thicker).

Female genitalia (figs. 128–135; 138–139). Antrum wide or small; ductus bursae variable, often wide, roundish to triangular (antrum noticeably spherical; ductus bursae formed from two semispherical lateral halfs fused together, wider than lamella antevaginalis, tapered strongly towards corpus bursae).
