The new generic name Nemoossis is proposed for the albulid species Pterothrissus belloci Cadenat 1937, a species endemic to the eastern Atlantic Ocean. Nemoossis differs from other genera in the family Albulidae as follows: longer dorsal-fin base, absence of supraneural bones, dorsal-fin rays [51–57 (mode 52)], vertebrae [total number 88–92 (91)], pored lateral-line scales [79–89 (84)], pre-dorsal-fin scale rows [3–8 (8)], head length [24–32 % (mean 30 %) of SL], pectoral-fin length [16–21 % (19 %) of SL], pre-dorsal-fin length [27–34 % (30 %) of SL], dorsal-fin base length [53–64 % (60 %) of SL], postorbital length [13–16 % (14 %) of SL], and upper caudal-fin length [18–31 % (24 %) of SL]. MNHN 1938-0002, 192 mm SL, is designated as a lectotype for P. belloci, and Bathythrissa dorsalis Günther 1877 is shown to be a junior synonym of P. gissu.
