FIGURE 6. A: neighbor-joining tree based on partial mitochondrial cytochrome oxidase subunit I (COI) nucleotide sequences showing the relationship in the genus Dictyosoma. B: neighbor-joining tree based on partial nuclear DNA recombination activating gene 2 (RAG2) nucleotide sequences showing the relationship in the genus Dictyosoma. The numbers on branches are NJ bootstrap values (>50%) obtained from 1,000 replications. The bar indicates a genetic distance of 0.005.

Fig. 4 in First Japanese Record and a Revised Diagnosis for Dictyosoma tongyeongensis (Osteichthyes: Perciformes: Stichaeidae)

Fig. 4. Neighbor-joining tree based on sequence variations in the mitochondrial cytochrome c oxidase subunit I gene. Newly determined sequences identified by specimen catalog numbers, remainder by DDBJ registration numbers (indicated by asterisks, determined in previous studies). Numbers at branches indicate bootstrap probabilities in 1,000 bootstrap replications. Scale bar equals 0.01 of Tamura and Nei's (1993) distance.
