背的软条 (总数) : 7 - 10; 臀鳍软条: 9 - 10; 脊椎骨: 32. Distinguished by the following autapomorphies: first proximal radial of dorsal fin of adult females located between arches neural of 14th and 15th vertebrae; wide and short trowel-like appendix of gonopodium at tip of R3; lateral border of left and right halves of trowel-like appendix of gonopodium concave; left and right halves of trowel-like appendix separated along approximately five-sixths of its whole extension; two round to elliptical dark blotches along ventral half of flanks; and presence of sexually dimorphic teeth (males teeth pointed with acute border; females teeth truncate, their superior border straight or slightly oblique. Further differs from its congeners by pleural ribs not associated with haemal arches in females; anal-fin proximal radials parallel in females. In addition, the number of epipleural ribs distinguishes Phallotorynus dispilos from P. jucundus and P. victoriae (13-14 vs. 11-12, respectively) (Ref. 56059).
区别的特征为下列的 autapomorphies了: 在第 14 与第 15个脊椎骨是神经的弓之间被设置的雌性成鱼的背鳍的第一近端动脉; 在 R3 的顶端的生殖足的宽与短像抹子一样附录; 左边与生殖足的像抹子一样附录的右边二等份的侧面边缘凹曲; 被分开的像抹子一样附录的左边而右边二等份大约沿着它的整个延长中的六分之五; 对椭圆的黑色斑块的二个圆沿着侧面的半边侧面; 而且有性别双型性齿 (雄性齿尖的和尖锐的边缘; 雌性齿截形 , 他们的上方毗邻直线或些微斜。 进一步有别于在雌性中是伴随着不的脉弓的胸膜肋骨的它的同類; 臀鰭近端的動脈平行的在雌性中。 除此之外，上側板肋骨的數字區別來自 P. jucundus 與 P. victoriae(13-14 vs.11-12, 分別地) 的 Phallotorynus dispilos 。 (參考文獻 56059)
