Abstract
The control region (D‐loop) of mitochondrial DNA (mtDNA) was amplified and sequenced for eight samples of the rhinogobies Rhinogobius maculafasciatus and R. giurinus from Taiwan and southern China. The control regions of both species are of 841–842 bp; the length of these sequences being the most compact among all known sequences in teleost fishes. Three conserved sequence blocks (CSB) were observed. The full D‐loop and tRNA Phe gene sequences were determined and compared with other fishes. The interspecific sequence divergence between the two species is 11.3–11.7%; and the intraspecific variation in R. guirinus 0.8–1.8%. Results suggest that the control region of Rhinogobius is informative for phylogenetic reconstruction at both intraspecific and interspecific levels in this gobiid genus.
