Table 5. Morphometries of Cyanocharax lepiclastus, new species. Standard length is expressed in mm; other measurements through head length are percentages of standard length; the last four entries are percentages of head length. All specimens are from upper rio Uruguay. Described ranges include measurements of the holotype MCP 25751, male, and following paratypes: MCP 12373 (2); MCP 12374 (6); MCP 12470 (3); MCP 12790 (2); MCP 12924 (9); MCP 12972 (1); MCP 12977 (8); MCP 13313 (6); MCP 13362 (15); MCP 14550 (4); MCP 14557 (26); MCP 15200 (21).

表5 新种鳞棘蓝脂鲤(Cyanocharax lepiclastus)的形态测量数据。标准体长(standard length)以毫米(mm)为单位;其余以头长(head length)为参照的测量值均以标准体长的百分比表示;最后四项测量值以头长的百分比表示。所有标本均采自乌拉圭河上游(upper rio Uruguay)河段。本次统计的测量范围涵盖正模标本(holotype)MCP 25751(雄性)及以下副模标本(paratypes):MCP 12373(2尾)、MCP 12374(6尾)、MCP 12470(3尾)、MCP 12790(2尾)、MCP 12924(9尾)、MCP 12972(1尾)、MCP 12977(8尾)、MCP 13313(6尾)、MCP 13362(15尾)、MCP 14550(4尾)、MCP 14557(26尾)、MCP 15200(21尾)。 测量性状 正模值 样本量 最小值 最大值 平均值 标准体长(mm,standard length) 44.5 103 26.3 46.3 37.6 吻端至臀鳍起点(snout to anal-fin origin) 52.1 103 52.1 58.8 55.4 吻端至背鳍起点(snout to dorsal-fin origin) 53.0 103 50.6 57.9 53.5 吻端至腹鳍起点(snout to pelvic-fin origin) 41.6 103 38.6 44.6 42.0 背鳍基底长(dorsal-fin base length) 11.9 103 8.6 12.1 10.4 臀鳍基底长(anal-fin base length) 36.9 103 32.8 40.0 35.9 尾柄长(caudal peduncle length) 12.4 103 10.0 13.9 12.1 尾柄高(caudal peduncle depth) 10.8 10 9.2 12.2 10.6 背鳍起点处体高(depth at dorsal-fin origin) 31.7 103 27.6 37.7 31.9 背鳍高(dorsal-fin height) 23.4 94 21.8 29.0 24.5 雄性腹鳍长(pelvic-fin length males) 13.5 43 13.2 16.6 14.6 雌性腹鳍长(pelvic-fin length females) - 54 11.1 15.0 13.1 胸鳍长(pectoral-fin length) 20.7 97 19.1 24.8 21.6 骨化头长(bony head length) 20.9 103 20.9 24.5 22.6 吻长(snout length) 21.5 103 18.9 26.2 22.2 上颌长(upper jaw length) 34.4 102 34.1 44.2 38.6 眼水平直径(horizontal eye diameter) 44.1 103 39.1 48.5 44.6 最小眶间距(least interorbital width) 36.6 103 32.0 39.3 35.3
