背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀鰭軟條: 12 - 13; 脊椎骨: 44 - 45. Distinguished from its congeners by the following unique combination of characters: head length 32.7-33.5% SL, head depth 14.2-15.3% SL, depth of caudal peduncle 7.5-8.8% SL, eye diameter 11.9-12.3% HL, a pattern of dark dots arranged in vertical columns on the sides of the body, a convex snout and a broad, shallowly incised humeral process (Ref. 41209).
Body shape (shape guide): elongated; Cross section: compressed.
用下列的獨特組合特徵與它的同類區別了: 頭長 32.7-33.5% SL ，頭部深度 14.2-15.3% SL ，尾柄 7.5-8.8% SL 的深度, 眼直徑 11.9-12.3% HL, 排列成垂直的縱列一個深色點的圖案在身體側邊上, 一個中凸的吻與寬, 水淺地呈鋸齒狀的肱骨突起。
Inhabits rivers and ponds in plains and submontane regions (Ref. 41236). It is usually dug out from the bottom of ponds where they lie buried in soft, wet clay.
在平原與在山麓的區域中棲息於河與池塘。 (參考文獻 41236) 通常它是被從池塘的底部挖出在那裡它們位於埋藏在柔軟，濕氣泥土之中。
