Dolopichthys sp.

( Figs. 1G , 4 )

Diagnosis. As for genus.

Geographical distribution. All seven valid species of Dolopichthys occur in the Atlantic Ocean and two of them were reported from the western South Atlantic near

the Brazilian EEZ: Dolopichthys danae Regan, 1926 , and D. pullatus Regan & Trewavas, 1932 (Pietsch, 1972, 2009). The small specimen of Dolopichthys reported here and identified only to genus, however, represents the first record of the genus in Brazilian waters. The specimen was collected near the seamounts off Rio Grande do Norte State, between depths of 830 and 1,030 m ( Fig. 4 ).

Material examined. NPM 4980 , 1 , 35 mm ( Fig. 1G ) , RV Antea, sta. AB2/54B, 3°45’17.2”S 34°41’04.0”W to 3°44’39.2”S 34°40’04.5”W, 830–1,030 m, 3 May 2017, 13:11–13:47 h.
