lateral-line scales 41–44 (mode 43, mean 42) (vs. mean 40 in  G. coriparoides); circumpeduncular scales 14–16 (mode 16, mean 16) (vs. mean 12 in  G. rivuloides, 18 in  G. coriparoides and 20 in  G. guentheri); longitudinal epithelial crests present on pre-dorsal scales (vs. absent in  G. coriparoides and  G. guentheri); anus centrally located between pelvic-fin base and anal-fin origin (vs. positioned at posterior one-third of distance from pelvic-fin base end to anal fin origin in  G. coriparoides and  G. guentheri).</p><p>Redescription.</p><p>Body elongated, dorsal body profile rising from nostrils to dorsal-fin origin, dropping along dorsal-fin base, then gradually sloping to caudal-fin base.

It usually appears in fast-flowing water with sandy bottoms and high turbidity, which is caused by fine sediments. It feeds in sand on the bottom of the river.</p><p>Remarks.</p><p>Gobio tchangi was originally described by Li (2015). In the original description,  G. tchangi is said to resemble  G. huanghensis, the only difference between the two species being the location of the anus (3.5 scales from anus to anal-fin base in  G. tchangi vs. 5 scales in  G. huanghensis). However, after carefully measuring specimens of both  G. tchangi and  G. huanghensis, the 3.5 scales from the anus to the anal-fin base in  G. tchangi were found to be incorrect. The holotype of  G. tchangi (ASIZB 56774, Fig. 5 A) has 5 scales between the anus and anal-fin base, and other specimens of  G. tchangi (ASIZB 56773, 56775–56778) also had 5–6 scales between the anus and the anal-fin base. Additionally, the scales between the anus and anal-fin base are not neatly aligned, making this an unreliable taxonomic trait. Therefore, we use the pelvic fin-anus distance and anus-anal fin distance to measure the position of the anus. The position of the anus did not differ between the two nominal species (pelvic fin-anus distance averaged 94.0 % of anus-anal fin distance in  G. tchangi, compared to 98.1 % in  G. huanghensis).</p><p>To further compare the morphological difference between  Gobio huanghensis and  G. tchangi, a PCA based on 22 specimens, including the holotype of  G. tchangi, was generated. The first three components contributed 98.3 % of the variance. Principal component 1 (PC 1) primarily represents the body size of the specimens, while PC 2 and PC 3 reflect their morphology. PCA loadings (Table 3) indicate that body depth, pelvic-fin base length, and anal-fin base length contribute most to PC 2. Even these characters have high loadings;  G. huanghensis and  G. tchangi were not separated in PC 2 or in PC 3 (Fig. 6).</p><p>Additionally, the type locality of  Gobio tchangi is Lanzhou City, Gansu Province, which is the same as that of  G. huanghensis . Based on the morphological comparisons and distribution, we treat  G. tchangi as a junior synonym of  G. huanghensis .</p></div>	https://treatment.plazi.org/id/3D8A9D08F39C5C77928A89D70AECAC4C	Public Domain	No known copyright restrictions apply.

In the Yellow River drainage, this species is distributed in both the mainstream, from Qingtongxia City to Lingbao City, and the tributaries, such as the Luohe, Qijiahe, Qinhe, and Hongnongjian Rivers, etc. (Fig. 4 B).</p><p>Habitat and biology.</p><p>Gobio rivuloides inhabits both the main stream and the tributaries of the Yellow River. It usually appears in fast-flowing water with sandy bottoms with gravel and pebbles. It feeds on the bottom of the river.</p><p>Remarks.</p><p>Romanogobio johntreadwelli and  R. amplexilabris were originally described by Bănărescu and Nalbant (1973) in the subgenus  Romanogobio under the genus  Gobio . This subgenus was treated as a genus in the subsequent studies (e. g., Naseka 1996). Naseka (1996) put these species into the genus  Romanogobio . The type locality of these species is the Qingshuihe River, a tributary of the Yellow River drainage in Shanxi Province. We tried to collect more topotypes of these two species, but unfortunately, the habitat of the type locality has been degraded and the river has dried up. We examined the holotype (Fig. 5 B, C) and paratypes of both species. The specimens have 40–42 lateral line scales, scales above lateral line 5.5, scales below lateral line 3, circumpeduncular scales 12, the anus positioned at middle of the pelvic-fin base end to the anal-fin origin or closer to the pelvic-fin base, a total of vertebrae 4 + 35, and a barbel relative elongated, reaching from vertical position of posterior orbit to posterior preopercle margin. All of the characters described above agree with those of  Gobio rivuloides .  Romanogobio johntreadwelli and  R. amplexilabris are junior synonyms of  G. rivuloides .</p><p>Gobio meridionalis (Fig. 5 D) was originally described by Xu in Chen et al. (1987). According to the original description, this species is similar to  G. rivuloides, but it has 12 circumpeduncular scales (vs. 14 in  G. rivuloides) and lacks black spots on its body. Following this original description, we identified some specimens as  G. meridionalis . We measured a series of characters of  G. meridionalis (including the paratypes) and  G. rivuloides and then conducted PCA for a detailed comparison. The first three components contributed 94.6 % of the variance. Principal component 1 (PC 1) primarily represents the body size of the specimens, while PC 2 and PC 3 reflect their morphology. The PCA loadings presented in Table 4 indicate that pelvic-fin base length, snout length, and pre-pectoral length contribute most to PC 2. Even these characters have high loadings;  G. meridionalis and  G. rivuloides could not be separated in PC 2, nor in PC 3. However, neither PC 1 versus PC 2 nor PC 2 versus PC 3 could separate these two species (Fig. 9). The difference in coloration should be related to water turbidity (Kottelat and Persat 2005); the high turbidity of water in the main stream causes the lighter color of  G. meridionalis, while the low turbidity of water in the tributaries causes the darker coloration and black spots of  G. rivuloides . The circumpeduncular scales with several traits were also reported in  G. lozanoi and  G. occitaniae (Kottelat and Persat 2005) . This result indicates that the number of circumpeduncular scales is an unreliable taxonomic characteristic, and the difference between 12 and 14 circumpeduncular scales should not be used to differentiate  G. meridionalis and  G. rivuloides .</p><p>We sequenced the Cyt b gene and reconstructed a phylogenetic tree for species within the genus  Gobio that inhabit the Yellow River drainage (Fig. 10). The phylogenetic tree shows that  G. meridionalis is nested within  G. rivuloides . To maintain the monophyly of  G. rivuloides, we propose that  G. meridionalis is a synonym of  G. rivuloides . Additionally, we calculated the genetic distances for the Cyt b gene (Table 5). The genetic distance between  G. rivuloides and  G. meridionalis is 0.0068, which is comparable to the intraspecific distance of  G. rivuloides (0.0062). This result further supports  G. meridionalis to be a junior synonym of  G. rivuloides .</p><p>Naseka (1996) also placed  Gobio rivuloides in the genus  Romanogobio . However, phylogenetic analysis (Fig. 10) suggests that  G. rivuloides should remain within the genus  Gobio .</p></div>	https://treatment.plazi.org/id/29C07B87E8D953458A73502660D73A27	Public Domain	No known copyright restrictions apply.
