簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 1; 背的軟條 (總數): 6; 臀鰭軟條: 9 - 12. Distinguished from its congeners by the following combination of characters: light transverse stripe, situated in occipital region between the opercular openings, thin and sinuous, sometimes discontinuous; pale region below dorsal and adipose fins mottled with brown spots; dark stripe in the axis of gill filaments in alcohol preserved specimens. Differs further from Microglanis parahybae and Microglanis garavelloi, the closest species geographically, by the following combination of characters: longer head length (28.3-32.1% SL vs. 25.5-28.5% and 25.2-30.2, respectively), shorter dorsal spine length (11.7-14.9% SL vs. 14.1-18.1% and 11.3-19.0), shorter pectoral spine length (12.5-19.7% SL vs. 19.4-22.7% and 18.5-26.2) (Ref. 58766).
與它的同類區分了藉由跟隨組合特徵: 被位於在鰓蓋開口之間的枕區之中的淡的橫跨斑紋, 細而彎曲的, 有時不連續的; 在背鰭與脂鰭鰭之下的灰白區域具有褐色斑點色斑; 在鰓絲的軸中的深色斑紋當保存在酒精中時保存的標本。 進一步不同於 Microglanis parahybae 與 Microglanis garavelloi, 最靠近的種地理地, 藉由跟隨組合特徵: 較長的頭長 (28.3-32.1% SL 和 25.5-28.5% 比較與 25.2-30.2, 分別地) ，較短的背棘長度 (11.7-14.9% SL 和 14.1-18.1% 比較與 11.3-19.0) ，較短的胸棘長度 (12.5-19.7% SL vs.19.4-22.7% 與 18.5-26.2).(參考文獻 58766)
