Sigmops Gill, 1883 View in CoL
Diagnosis. The genus was reappraised by Miya, Nishida (2000), who included in Sigmops five species previously allocated in Gonostoma : Sigmops bathyphilus (Vaillant, 1884) , S. ebelingi (Grey, 1960) , S. elongatus (Günther, 1878) , S. gracilis (Günther, 1878) , and S. longipinnis (Mukhacheva, 1972) . Sigmops can be distinguished in the Gonostomatidae by the absence of elongate rays in dorsal and anal fins; head and trunk nearly as long as tail; no photophores on isthmus; two rows (lateral and ventral) of photophores; SO present; OA 11–21; IC 32–43; first 4–6 IV forming an arch or an ascending line; palatine teeth uniserial; upper jaw teeth in a single row, with a series of long, slender, subequal teeth interspaced with shorter teeth (Grey, 1964; Mukhacheva, 1972; Schaefer et al., 1986a).
