Opsin gene topology of 145 sequences based on the single best ML tree under the BIC best-fit protein model LG + F + I + G4, LogL = -39087.214. UFBootstrap values based on 10,000 replicates are given at nodes (UFBootstrap values < 50 not shown). Tree was rooted to bovine rhodopsin outgroup. Jewel beetle taxa are bolded
