Abstract
There is increasing evidence that species diversity is underestimated in the current taxonomy of widespread freshwater fishes. The bagrid species T. albomarginatus s.l. is mainly distributed in the lowlands of South China, as currently identified. A total of 40 localities (including the type locality), which covers most of its known range, were sampled. Molecular phylogenetic analyses based on concatenated mtDNA and nuclear genes recover nine highly supported lineages clustering into eight geographic populations. The integration of molecular evidence, morphological data, and geographic distribution demonstrates the delineation of T. albomarginatus s.l. as eight putative species. Four species, namely, T. albomarginatus, T. lani, T. analis, and T. zhangfei sp. nov. and the T. similis complex are taxonomically recognized herein. Moreover, T. zhangfei sp. nov. comprises two genetically distinct lineages with no morphological and geographical difference. This study also reveals aspects of estimation of divergence time, distribution, and ecological adaption within the T. albomarginatus group. The unraveling of the hidden species diversity of this lowland bagrid fish highlights the need for not only the molecular scrutiny of widely distributed species of South China but also the adjustment of current biodiversity conservation strategies to protect the largely overlooked diversity of fishes from low-elevation rapids.

Abstract
Mitochondrial DNA cytochrome b and d-loop sequences (2,137 bp) in 65 specimens of Sarcocheilichthys sinensis from five populations were identified as two lineages (I and II). The pairwise genetic distance between lineages I and II was 1.94%. SAMOVA analyses suggested that the best grouping occurred at three groups, Yangtze, Qiantang and Minjiang Rivers. High haplotype diversity (0.949) and low nucleotide diversity (θ π = 1.067%) were detected. The results of the neutrality tests, mismatch distribution and approximate Bayesian computation (ABC) did not support demographic expansions. The results of phylogenetic analysis, statistical dispersal-vicariance analysis (S-DIVA), ABC, MIGRATE-N and the time to the most recent common ancestor (TMRCA) indicated two colonization routes. First, before the Wuyi Mountains lifted, S. sinensis dispersed from the Yangtze River to the Minjiang River. Second, during glaciation, the continental shelf was exposed, which contributed to the dispersion of populations from the Yangtze River.
