Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); bimargaritoides: From the species name bimargaritatus, adorned with two pearls, and oides, meaning resembling, alluding to the similarity of the terminal barbel filaments of the two species..

背的软条 (总数) : 25; 臀鳍软条: 38. Two terminal bulbs separated by a short interspace, 0.5-1.1 times the length of distal bulb. Barbel length 44-59% SL. Terminal filament long (21-28% SL), with 2 long branches arising closely together at 6-11 distal-bulb lengths from the distal bulb (at 8.3 - 12.6 cm specimens); all long branches with conspicuous closely-spaced bulblets. Stem of filament with no bulblets and with 1-6 short, slender branches in its basal half. Barbel without melanophores (rarely very sparse on axis of stem). Middorsal paired spots under skin between occiput and dorsal-fin base 8 (Ref. 11333).
被一个短间隙分开的二个末端的球茎,0.5-1.1 倍于末稍球茎的长度。 触须长度 44-59% SL。 末端的丝状突起长的 (21-28% SL), 有两个在 6-11个末稍球茎长度从末稍球茎一起出现接近地的长的分支 (在 8.3 点 - 12.6 公分标本); 所有的长分支有明显的间隔很密的球茎。 丝状突起的茎在它的基部一半中没有球茎而且 1-6个短又细长的分支。 没有黑色素细胞的触须.(非非常稀疏的在茎的轴上) 在后脑部与背鳍基底 8 之间的皮肤下面的背面中央的成对斑点.(参考文献 11333)
Mesopelagic (Ref. 58302).
