Comment: Chaceon species are very close to each others and can be confused. Present determination is based on red color and dactyl of P5 dorsoventrally depressed (Manning & Holthuis, 1989). The species was already collected in the 1990's during the R/V Polka campaigns at similar depths (Paulmier, 1993; Poupin, 1994).
