Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); posti: Named for Alfred Post.
Eponymy: Alfred Post (d: 1935) is a German zoologist who worked at Hamburg’s Institut für Seefischerei. He was honoured for his contributions to our knowledge of deep-sea fishes and his continuing services to the ichthyological community. (Ref. 128868), visit book page.

背鰭 (合計) : 25; 臀鰭: 38; 脊つい: 67. Two terminal bulbs separated by a long interspace, 1.3-2.5 times the length of distal bulb. Barbel length 43-50% SL. Four long filaments, arising together from distal end of distal bulb or from a short stem; all with numerous conspicuous bulblets of variable size. Distal bulb 0.9-1.6 times length of proximal-bulb. Axis of stem lightly, often sporadically pigmented; axis between bulbs and in filament lightly or unpigmented. Suggestion of spot at base of distal bulb in one specimen. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).
Body shape (shape guide): elongated.
