Coelorinchus asteroides

discussion

REMARKS. — First recorded from Taiwan by Chiou et al. (2004 b). Among the Taiwan members of the genus, C. asteroides is most likely to be confused with C. anatirostris, but it has fewer platelike scales on the median rostral ridge, and the spinule rows on these scales are arranged radially in all directions, compared to the lateral and posterior orientation of rows in C. anatirostris.
