简单描述 型态特徵 | 形态测量图

Paedocypris progenetica is distinguished from Paedocypris micromegethes by: a smaller maximum size (male 9.8mm, versus 11.6; female 10.3mm, versus 11.4), keratinized pad in front of male pelvic fins as a projecting knob (versus flat to slightly swollen), breeding tubercles on the dentary arranged in a straight row, without forming a cluster (versus forming a cluster of up to five closely set individual tubercles, subdistally on the lateral side of the dentary, supported by a conspicuous lateral bony extension), pelvic fins of female vestigial, or often missing (versus smaller than in male but similarly shaped), presence of pre-anal-fin-fold in female (a character unique among teleosts; versus absent in both sexes), dense small chromatophores in deep layer on abdomen appearing as a continuous patch, tiny black vermiculations on belly from throat to anus, including on male's pre-pelvic keratinized knob (versus large superficial, isolated chromatophores on belly from throat to anus, absent on male's keratinized pad), numerous small, contiguous chromatophores on middorsal line, organized in 3-5 rows, forming a broad stripe (versus few large isolated chromatophores, forming 1-3 irregular rows), pelvic-fin rays plain brown (versus with rows of spots).
Paedocypris progenetica 被与 Paedocypris micromegethes 区分被: 一个较小的最大体长 (雄鱼 9.8 mm, 对 11.6; 雌性的 10.3 mm, 对 11.4), keratinized 衬垫在雄鱼腹鳍之前作为一个被在齿骨上繁殖小瘤的突出的疖瘤 (对平坦的到些微肿大) 没有形成一个群 (对形成一个向上到五的群紧密地在一起个别的小瘤, 子末梢部地在齿骨的侧面侧边上, 由显著的侧部支撑多骨的延长) 排列成直的列腹鳍了雌性的退化, 或時常不見的 (對小的超過在雄魚中但是同樣形狀), 有前臀鰭-摺層母魚 (一個特徵獨特的在硬骨魚之中; 對不存在於兩性), 密集的小色素胞在深地分層堆積腹部之上呈現一連續的小區塊, 極小的黑色蠕蟲爬跡形的裝飾腹面之上從咽喉到肛門, 包括雄魚之上前腹鰭 keratinized 癤瘤 (對大的表面, 孤立的色素胞在從咽喉到肛門的腹面上, 在雄魚的 keratinized 襯墊上不存在), 很多的小, 鄰近的色素胞背面中央的之上線, 組織在 3-5 列, 形成一個寬的斑紋 (對少數大的孤立色素胞, 形成 1-3 不規則的列), 腹鰭鰭條全褐色的 (對有數列斑點).
