Notes on Platygonia undecimmaculata ( Fowler, 1899) , reinstated combination

Tettigonia undecimmaculata was described by Fowler (1899) ( Fig. 7 ) based on one female (holotype) ( Fig. 8 ) from the Province of Chiriquí, Panama ( Young 1965). Melichar (1925) transferred T. undecimmaculata to Platygonia . Young (1977: 1105) studied the holotype and stated that this species was “possibly correctly placed in Platygonia as Melichar decided.” Nevertheless, Young (1977) did not formally include T. undecimmaculata in Platygonia , preferring to treat it as a species of uncertain position. This action was followed by McKamey (2007: 343), who, however, misspelled the specific name (“ unidecimmaculata ”). The species reappeared as a member of Platygonia in Wilson et al. (2009). Based on the triangular crown of the holotype, which is strongly produced anteriorly ( Fig. 8 ), it appears to us that the inclusion of T. undecimmaculata in Platygonia might be correct. Accordingly, we have tentatively included the species in our key. Likewise, based on the color pattern of the holotype (see Wilson et al. 2009), which has no abdomen, hind wings, and metathorax ( Young 1965), we have attempted to include P. zea ( Ecuador) in the key; the latter species was not included in Young’s (1977) key to Platygonia species.
