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..

Size / Weight / umur
Maturity: Lm ?  range ? - ? cm
Max length : 12.6 cm SL jantan/; (Ref. 11333); 11.8 cm SL (female)
duri punggung lunak (Keseluruhan (total)) : 25; Sirip dubur lunak: 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).
