Etymology: Mystus:Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335); impluviatus:From the Latin impluvium, referring to a skylight, in allusion to the second posterior fontanel on the supraoccipital of this species.
Environment: milieu / climate zone / 深度上下限 / distribution range 生态学
背的软条 (总数) : 6 - 7; 臀鳍软条: 11 - 13; 脊椎骨: 37 - 39. Differs from both Mystus castaneus and Mystus nigriceps in having a second posterior fontanel on the supraoccipital. It further differs from Mystus castaneus in having a shallower adipose fin (4.7-6.0% SL vs. 6.1-7.0), smaller serrations on the posterior edge of the pectoral spine (maximum height of serrations 3.6-4.8% of spine length vs 6.9-8.0) and a more deeply forked caudal fin with a more slender upper lobe. Further differs from Mystus nigriceps in having a longer adipose fin base (31.6-36.1% SL vs 26.3-31.4), longer second and third dorsal fin rays, causing the dorsal fin to appear less rounded, and a brown body with a distinct darl triangular patch on the base of the caudal peduncle (vs. greenish gray body with a diffuse dark triangular patch on the base of the caudal peduncle). Body shape (shape guide): elongated. 在上枕骨上在有一个方面有别于 Mystus castaneus 和 Mystus nigriceps 第二的在后部的囟门。 它进一步在有一个方面有别于 Mystus castaneus 较水浅的脂鳍 (4.7-6.0% SL vs.6.1-7.0), 较小的锯齿在胸棘 (锯齿的最大高度 3.6-4.8% 的棘长度相对 6.9-8.0) 的后缘上与一更深深，叉型尾具有一个更细长的上叶。 进一步在有一个方面有别于 Mystus nigriceps 较长的脂鳍基底 (31.6-36.1% SL 相对 26.3-31.4), 比较长的第二个与第三个背鳍鳍条, 导致背鳍显得比较不圆形, 与在尾梗的基底上的一个褐色身体有明显的 darl 三角形的小区块.(vs. 灰绿色身体有一个扩散的深色三角形的小区块在尾梗的基底上)
Facultative air-breathing in the genus (Ref. 126274); Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
