Etymology: The specific name “orientale” means from the Eastern, in referring to the distribution around northwestern Pacific Ocean.

Diagnosis: A species of Lestidium with light organ duct extending to beyond anterior margin of eye. It is most similar to Lestidium atlanticum and can be distinguished by having relatively more prehaemal vertebrae (37‒40 vs. 36‒37), a shorter snout (snout length 9.7–10.4 vs. 10.4–11.5% SL), shorter jaws (upper jaw 8.6–10.1 vs. 9.9–11.3% SL; lower jaw 11.9‒13.7 vs. 13.5‒14.8% SL) and relatively deep head (head depth 31.2–33.9 vs. 27.6–31.5% HL).
