Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); perplexus: From its perplexing combination of characteristics also found in longibarba and curtatus.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino pelagic-oceanic; distribuzione batimetrica 0 - 2600 m (Ref. 11333). Tropical
Western Pacific: China and Papua New Guinea.
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 13.4 cm SL maschio/sesso non determinato; (Ref. 11333); 14.7 cm SL (female)
Raggi dorsali molli (totale) : 24; Raggi anali molli: 35; Vertebre: 67. A single terminal bulb, its length more than twice its width, with a terminal projection that may be undeveloped or up to 55% of bulb length. Bulb and projection combined 0.8-2.2% SL. Barbel 67-83% SL, except in the smallest specimen. Axis of stem moderately to fairly dark pigmented proximally, becoming lighter or unpigmented distally. External chevron-shaped or roundish striated areas unpigmented, becoming closely spaced distally. Widely spaced spherical inclusions present in distal 1/3 to 1/2 of stem, sparse or absent before bulb. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 9 (Ref. 11333).
