Etymology: Astronesthes: Greek, astra = ray + Greek, esthes, -es = suit, something used to wrap (Ref. 45335); lucibucca: The name is derived from the Latin 'lux' (light) and 'bucca' (cheek), referring to the unique specific characteristic (the presence of luminous patches in the cheek region) (Ref. 27676).
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino pelagic-oceanic; distribuzione batimetrica 150 - 210 m (Ref. 27676). Subtropical
Southeast Pacific: Type specimens were taken from the transition zone between the subtropical and subantarctic gyres. Possibly, it is more widely distributed in the transitional zone of the southern hemisphere, i.e., in the southern Subtropical Convergence Region. High Seas only.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 15 - 16; Raggi anali molli: 14 - 16; Vertebre: 45 - 46. Last photophore of VAL series in advance both of origin of anal and last photophore of VAV series. Luminous patches on head, when fully developed in fish > 9.5 cm SL, appearing on upper, middle and lower parts of gill cover and behind eye, on cheek; no luminous patches on body. In immature fish < 6 cm SL, chin barbel fully developed, longer than head, its swollen tip forming a narrow lobe with weak oblique ribs; distal part of barbel twisted at a right angle (Ref. 27676).
Body shape (shape guide): elongated.
