Comment: We are here designating Lacerta tequ ix i n Linnaeus as the type species of Gusta Fleming, 

 because this firmly fixes the generic name as a junior synonym of Tupi namb is . Use of one of the 

 other species assigned by Fleming to Gusta could result in replacement of a well-known genus, 

 such as Crocod ilurus .
