Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 6; Anale zachte stralen: 12 - 14; Wervels: 28. Distinguished from all members of the Microglanis parahybae species complex by the following combination of characters: pectoral and anal fins mottled or with relatively faint bands; caudal fin emarginate; dark brown saddles on trunk; caudal peduncle with faint to dark blotch irregularly shaped; caudal fin lightly mottled with narrow vertical dark brown band across central portions of lobes; dark saddle beneath adipose fin not extending ventrally to anal fin as continuous bar; continuous portion of lateral line not reaching vertical through origin of adipose fin; tip of pectoral spine as distinct bony point; wider head; a dark blotch beneath adipose fin not extending to anal fin; distal portion of anal fin without dark band; dark saddle beneath adipose fin extending ventrally to more than the half of trunk and a light oval spot located below dorsal-fin spine (Ref. 86273).
