Etymology: Amblyceps: Greek, amblys = soft, darkness + Latin, ceps = head (Ref. 45335); platycephalus: The specific name is a noun in apposition, derived from the depressed head. More on authors: Ng & Kottelat.

Morphology | Morphometrics
soft rays: 15;
Vertebrae: 41. Differs from all members of the genus by the unique combination of the following characters: posterior edge of adipose fin rounded; body depth at anus 11.5% SL; head depth 8.3% SL; eyes small, dorsolaterally situated and subcutaneous, diameter 4.8% HL; 41 vertebrae, lower jaw strongly projecting; forked caudal fin. Distinguished from all Indochinese congeners in having a strongly depressed head (depth 8.3% SL vs. 8.8-15.8) with lower jaw strongly- projecting (vs. non- or weakly-projecting); and 20 principal caudal-fin rays (vs. 17). Can be differentiated from A. mucronatum, A. foratum, and A. variegatum in having a smaller eye diameter (4.8% HL vs. 5.1-8.5% HL) (Ref. 37785).
Specimens were obtained from villagers fishing with cast-nets and harpoons among large boulders; thus, actual habitat unknown. However, the stream in the area of occurrence is with swift to fast current among large boulders, or small cascades, and further downriver, current is quieter, over large stones and gravel (Ref. 37785).
