Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); orientalis: Named for its distribution in the orient.
Environment: milieu / climate zone / rango de profundidad / distribution range

Tamaño / Peso / Age
Madurez: Lm ?  range ? - ? cm
Max length : 16.0 cm SL macho / no sexado; (Ref. 559)
Radios blandos dorsales (total) : 24; Radios blandos anales: 36; Vértebra: 68. Two terminal bulbs separated by a very short interspace (0.5-0.6 times length of distal bulb). Barbel 50-53% SL. Terminal filament short, 4.1-5.3% SL without branches. Distal bulb 1.8 times length of proximal bulb in small specimens, 0.7 in larger ones. Proximal bulb in larger specimens large for its size, 1.5 mm at 118 mm SL. Barbel without pigment in smaller specimens; larger ones with fairly dense pigment in proximal part of axis, little or none in distal part. External chevron-shaped or roundish striated area on stem not pigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
Body shape (shape guide): elongated.
Mesopelagic species (Ref. 559).
