简单描述

背棘 (总数) : 12 - 14; 背的软条 (总数) : 5 - 7; 臀棘: 13 - 14; 臀鳍软条: 6 - 9; 脊椎骨: 27 - 28. Distinguished from congeners, except Parosphromenus linkei and P. paludicola, by having 1-3 conspicuous black spots in the middle of the midlateral dark stripe. Differs from both in having a rounded caudal fin; further differs from P. linkei by having fewer segmented anal rays (6-9 vs. 10-12), and a different color pattern in the dorsal (blackish stripe, proximal anteriorly, subproximal posteriorly, bordered externally by a row of lighter spots), anal (almost hyaline proximal stripe, with blackish mark on soft anal) and caudal (with indistinct vertical rows of darker spots anteriorly) fins (vs. all unpaired fins uniformly greyish brown with several rows of minute hyaline spots). Can be differentiated from P. paludicola in having 12 spines in the dorsal fin (vs. 17-19). Further differs from most other species of the genus by a combination of dorsal and anal fin rays formulae and details of color pattern (Ref. 56232).
Body shape (shape guide): elongated.
与同类区分了, 除 林氏副斗鱼〔Parosphromenus linkei〕 与 P. paludicola, 在侧面中央深色的斑纹的中央中借着具有 1-3个显著的黑色斑点。 有别于在有一个圆形的尾鳍中; 进一步有别于 P. linkei 在背部 (黑色的斑纹, 近端的前面地, 子近端的在后部地, 外部地被一列淡色的斑点毗邻) 中借着具有比较少的分段臀鳍鳍条 (6-9 vs.10-12), 与一个不同的彩色斑纹, 肛门的 (几乎透明近端的斑纹, 有黑色的標誌軟的之上肛門的) 而尾部的 (前面地有不明顯的呈縱向列的較深色的斑點) 鰭.(vs. 對細小透明的斑點的幾排感到均勻灰褐色的所有的不成對的鰭) 能從 P. paludicola 被區別在背鰭中有 12根棘.(vs.17-19) 進一步有別於一個背鰭棘條與臀鰭棘條公式和彩色斑紋的細節組合的本屬的其他大部分種。 (參考文獻 56232)
