Euchiloglanis longicauda Yue, 1981: 183 – 185 (Jiazhuan of Bama Co. in Guangxi Prov.).
Pareuchiloglanis longicauda: Chu, 1989: 291 – 292 (Hongshui-he in Guizhou and Guangxi Prov.); Chu & Mo, 1999: 165 – 166 (Hongshui-he); Thomson & Page, 2006: 79 (Xijiang drainage, China); Yang & Zhang, 2006: 421 – 423 (Bama Co., Guangxi Prov.).
3.2.1 | Material examined
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).
