Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 20; Raggi anali molli: 32. This species is distinguished by the a unique barbel structure: barbel short, its length 19.6% SL; terminal bulb rounded and large, its greatest width almost 5 times of stem width; presence of a simple, thin appendage of branch arising near base of terminal bulb with its distal tip extending beyond terminal bulb; two long (longer than terminal bulb) and one short (as long as barbel diameter) filaments on distal tip of terminal bulb; branch and terminal filaments without pigments, luminous swellings, and secondary branches; stem unpigmented, axis pigmented; further unique meristic characters in the subgenus include, D 20; A 32; IP 8; PV 33; VAV 14 (Ref. 121636).
Cross section: compressed.
This species was collected from a depth shallower than 100 m, by a mid-water trawl that was targeting the Sakura-shrimp (Lucensosergia lucens) (Ref. 121636).
