Distinguished from its only congener Pareiorhina rudolphi by the following characters: anterior profile of head elliptical in dorsal view; snout sloping abruptly towards its tip in lateral profile; ventral border of rostral region and dorsal border of upper lip covered with odontodes; anterior ends of premaxillae and dentaries strongly sloped inwards; lower lip moderately developed and well separated from anterior margin of pectoral girdle; lower lip with a smooth, unpapillose band just behind the toothed portions of dentaries, which is especially conspicuous just behind the symphysis; anterior regions of roof and floor of mouth immediately behind premaxillae and dentaries, respectively, covered with rounded papillae; interorbital width 36.6-39.4% HL; postdorsal surface of trunk with a low, elongate ridge formed by 10-13 raised median unpaired plates; posteriormost 2-3 median plates without sensory pores of lateral line; inferior surfaces of first pectoral, pelvic and anal-fin rays covered by conspicuously pointed odontodes; and lower counts of body plates (25-27 dorsal plates; 17-22 mid-dorsal plates; 25-27 median plates; 18-20 mid-ventral plates; and 19-23 ventral plates) (Ref. 52873).
在特征之后与它的唯一的同类 鲁道夫锉颊鲶〔Pareiorhina rudolphi〕 区分了藉由: 从背面观察的头部椭圆形的前面轮廓; 吻倾斜的突然地向它的顶端在侧面的轮廓中; 嘴区域的腹边缘与上嘴唇的背部边缘覆盖着齿了; 前颌骨与齿骨的前端强烈地斜的内部; 下唇适度发展的而且与肩带的前缘分得很开; 下唇具有一个平滑又不乳突状的条纹在齿骨的有齿部分正后方, 是尤其显著的在愈合处正后方; 分别地，顶部的前面区域与嘴底在前颌骨与齿骨正后方,覆盖着圆形的乳突; 眼间骨宽度 36.6-39.4% HL; 後背表面軀幹有被由 10- 形成的一個低又細長的脊 13 升起了中央的不成對的碟; 沒有側線的感覺小孔的最後面的 2-3個中央的碟; 第一個胸鰭的下方表面, 腹鰭與臀鰭鰭條被顯著尖的齒蓋著了; 而且身體碟的較少的數目 (25-27個背部的碟; 17-22個背部中央碟; 25-27個中央的碟; 18-20 腹面中央碟; 而且 19-23個腹的碟).(參考文獻 52873)
