Diagnosis. Males of P. g a l e n i a have the tuft of erect scales near the base of the costa characteristic of P. crocoptycha and P. s i m p l e x (see Table 1). The male genitalia of P. galenia are somewhat variable (Figs. 5, 6) but usually can be distinguished from those of P. s i m ­ plex by the presence of a thorn from the venter of the valva at about 0.4 the distance from the base to the apex of the valva, a blunt thorn at the distal end of the aedeagus, and the longer, more slender valva (Figs. 5, 6); they can be can separated from those of P. crocoptycha by the absence of the longitudinal comb in the disc of the valva, although a trace of the latter is weakly developed in some specimens (Fig. 5).
Description. Male forewing (Fig. 34) with tuft of erect scales near base of costa. Male hindwing with hairpencil in fold of vein CuP, with dense beige­orange scaling on both sides of fold. Male genitalia (Figs. 5, 6) with uncus, socii, and gnathos as described for the genus. Transtilla with small mesal lobe. Valva similar to crocoptycha, weakly attenuate nearly from base to apex; venter with sacculus near straight, followed by small convexity with variably developed thorn near middle; disc without comb, but with weakly developed, linear patch of tiny, blunt bumps. Aedeagus as described for genus, with small blunt, curved process extending beyond distal end; vesica with two groups of cornuti: a long, dense patch of short, spinelike cornuti and a basal group of longer spines. Female genitalia (Fig. 20) with lamella antevaginalis short; proximal corners developed, lacking V­shaped membranous pockets; colliculum membranous, twisted.

Distribution and biology. Ptychocroca galenia is recorded from Talca to Malleco provinces (from about 35° to 39° S latitude) in Chile, ranging from near sea level to about 1600 m. It has been collected from November through January (with a single March record), suggesting a single generation annually.
