Figure S7. Nuclear intron networks

Statistical parsimony networks of nuclear intron sequences: (a) 08352, (b) 09385, (c) 10179, (d) 11887, (e) 12884, and (f) 15349. Each circle represents a haplotype; the size of the circle is proportional to a haplotype’s frequency. Small black circles represent inferred haplotypes. Colors distinguish the four species recognized in this study.核内含子序列的统计简约网络：(a) 08352、(b) 09385、(c) 10179、(d) 11887、(e) 12884 及 (f) 15349。每个圆形代表一个单倍型（haplotype），圆形尺寸与单倍型的频率呈正比。小型黑色圆形代表经推断得到的单倍型。不同颜色用于区分本研究中所认定的四个物种类群。
