Etymology. Rhachotropis abyssalis sp. nov. is named for the abyssal habitat in the northern Ross Sea from which the species was collected. Diagnosis. Body delicate. Rostrum longer than head.

Pereonite 3 indented. Urosomite 1 bearing dorsal process, urosomites 2 and 3 smooth. Telson cleft, long and narrow. Description. Antenna 1 and 2 equal in length. Antenna 1 article 2 of peduncle with several plumose setae, article 2 slightly shorter than first article, twice as long as third article; flagellum 67 articles, the first 22 articles very short and bearing many setae. Antenna 2 peduncle article 4 shorter and wider than article 5, with several plumose setae, flagellum of 65 articles.
