A Haplotype network from 63 sequences, including 57 Tetrix bolivari individuals, 4 Tetrix species, 1 Alulatettix yunnanensis and 1 outgroup (Teleogryllus emma) B Haplotype network of 57 Tetrix bolivari individuals combined with the morph types. Circle size is proportional to haplotype frequency. Lines drawn between haplotypes represent mutation events identified by the numbers corresponding to the positions at which the mutations were observed. Red points represent hypothetical haplotypes (median vector). Colours in B represent morph types. Yellow areas represent type A and black areas represent type B.
