Key to species (based on females) after Boxshall & Halsey (2004, p.176) :
1 - Female P5 lacking setal element on middle segment; distal segment drawn out into tapering point and carrying large, serrated inner spine ........ R. rostrifrons.
1' - Female P5 with 1 or 2 inner setae on middle segment; distal segment with 2 inner plumose setae and terminal spine (which may be short and naked or long and plumose) ...... 2.
2 - Female P5 with naked outer terminal spine, shorter than its segment ........ R. cornutus.
2' - Female P5 with terminal spine plumose (at least on one side), much longer than segment ..... 3.
3 - 3rd and 4th pedigerous somites each with paired spinous processes dorsally on posterior margin ...... R. gigas. |
