South Pacific : Two males, two females (ZMUC CRU-9935); west of Galapagos Is. [00°18’S 99°07’W]; Dana Stn. 3558 II, 3000 mw, 18 Sept. 1928.

Body length of females up to 8.0 mm, of males up to 6.0 mm or slightly more. Antennae 1; peduncular articles and callynophore relatively broader and longer in males; terminal article elongate, slightly longer than preceding article in males, slightly shorter in females. Antennae 2 slightly shorter than A1 for females, about 0.8x A1 for males; antennal gland grossly inflated, slightly deeper than long, about as long as following articles combined. Gnathopod 1; basis slightly shorter than remaining articles combined; dactylus slightly narrowed, length about half propodus. Gnathopod 2: length about 1.4x G1; basis marginally longer than remaining articles combined (excluding dactylus); dactylus length about 0.4x propodus. Pereopods 3 & 4 similar in structure but P4 is slightly longer; both longer and stronger than any other pereopoda. Pereopod 4; basis length about twice merus; carpus length twice merus; propodus length 1.4x carpus; dactylus length about one third propodus. Pereopod 5 strongly subchelate with propodus and dactylus rotated at right angles to body; length about 0.6x P4; basis length 1.7x merus; carpus length about 0.8x merus; propodus length about 1.5x carpus, relatively broad forming subchela with dactylus, anterodistal margin with several pairs of short, strong setae; dactylus ...
