Lepidotrigla guentheri is a species of marine, demersal ray-finned fish from the family Triglidae, the gurnards and sea robins.

[1] Lepidotrigla guentheri was first formally described in 1879 by the German zoologist and palaeontologist Franz Martin Hilgendorf with the type locality given as Tokyo.

[1] Lepidotrigla guentheri is found in the Northwestern Pacific Ocean from Taiwan and the East China Sea north to Korea and Japan.

[2] It is a demersal fish found on sandy and muddy substrates along the edge of the continental shelf at depths between 70 and 280 m (230 and 920 ft).

[1] Lepidotrigla guentheri feeds on the substrate and its diet is dominated by crustaceans particularly Leptochela sydniensis, amphipods, and crabs, as well as small amounts of stomatopods, mysids, cumaceans, krill, polychaetes, and copepods.
