(figs. 5B and 6). This whiplike seta on the maxilliped can be seen in lateral view of the head without dissection (figs. 1B and 5B). In many of the male specimens examined the large second gnathopods were seen “reversed,” or upside down, reflecting an essentially prehensile condition. Males and females of

is consistent among males and females: both rami are lanceolate and their posterior margins are armed with robust setae (figs. 6D and 6E). Another notable feature limited to males is the broadly convex palm of the gnathopod 1; the anterodistal corner is weakly produced and covered with fine scales. The dactyl length equals that of the palm. In male gnathopod 2 the palm exceeds the length of the dactyl and the proximoposterior corner lacks robust setate.
