Trapinch - Nakkurā
Vibrava - Biburāba
Flygon - Furaigon
Bagon - Tatsubei
Shelgon - Komorū
Salamence - Bōmanda
Flygon already had the "-gon" part in Japanese name which happened to go through localization, even the whole name is the literal translation. Salamence's family hadn't.
This means, that Flygon couldn't get the name from Salamence because it was already its.
Also calling antlion a "salamander" is just stupid.
