SWFC 00120657, 00120818, 2 ex., 45.2 – 101.2 mm L S; China: Guangxi Prov.: Lingyun Co.: Yuhong Town: Nabao Village : Buliu-he (24 30 0 34.79 00 N, 106 31 0 40.95 00 E) .

3.2.2 | Diagnosis

Pareuchiloganis longicauda is distinguished from the congeners of the large-gill-opening group with long caudal peduncle by the following combination of characters (Table 1): anal-fin ray i, 4½ (v. i, 3½ in P. arcuatum sp. nov., P. posteranalis sp. nov. and P. salicesbarba sp. nov.); tip of the maxillary barbel pointed and extending beyond the lower corner of the gill opening ( v. only reaching the lower corner of the gill opening in P. salicesbarba sp. nov.); anal-fin origin about midpoint between the distance from pelvic-fin insertion to caudal-fin base ( v. located at about 2/5 of distance between pelvic-fin insertion and caudal-fin base in P. arcuatum sp. nov.); adipose-fin origin located at about 3/4 of distance between pelvic-fin insertion and anal-fin origin, the length of dorsal-fin base longer than the longest branched dorsal-fin ray ( v. about 2/3 of distance between pelvic-fin insertion and anal-fin origin, the length of dorsal-fin base shorter than the longest branched dorsal-fin ray in P. arcuatum sp. nov. and P. salicesbarba sp. nov.); caudal-peduncle depth 26.2 – 26.3% of caudal-peduncle length (v. 14.1 – 17.8% in P. arcuatum sp. nov., 27.2-31.3% in P. posteranalis sp. nov. and 18.3 – 23.0% in P. salicesbarba sp. nov.).

Morphometric and meristic data are given in Tables 1 and 2. Dorsal-fin rays i, 5½; anal-fin rays i, 4½; pectoral-fin rays i, 14 – 15; pelvic-fin rays i, 5 – 6; branched caudal-fin rays 5 + 6; vertebra 23 + 17 = 40 (n = 1).

3.2.3 | Distribution

Only known from the Hongshui-he in Guangxi Prov., belonging to the main stream of the Xi-jiang in the Pearl River drainage (Figure 4).
