Phthinia fasciata Freeman

P. fasciata Freeman, 1951: 54 , fig. 109 (3 terminalia). Type-locality: Chile, Llanquihue, Peulla. Holotype 3, NHM.

Diagnosis. M1 and M2 strongly diverging at base, M1+2 shorter than r-m. Gonostyle with one basal and two apical projections.

Comments. The comparison of the new species of Phthinia from Chile described here with Freeman’s (1951) illustration of the male terminalia of his species suggests some mistakes on his drawings and interpretations, as commented above. His drawings of P. fasciata ( Freeman, 1951, fig. 109) seem to mistake the distal extension of the gonocoxite with the gonostyle itself. It seems more likely that the gonostyle corresponds to one of the distal furcations of the “style”, the large distal projection being an extension of the gonocoxite, as in the remaining Neotropical species of the genus. The drawing also seems to be in ventral view, despite the indication to the contrary.
