 Rostral projection broadly triangular, with the tip narrowly produced. Urosome

 well defined and densely spinulose. last segment about the length of the preceding

 with a well-marked keel running along the dorsal face; apical seta3 of moderate 

 length and distinctly spinulose. Anterior antenna rather large, but composed of 

 only tj articulations, the last 2 being confluent; 2nd joint produced behind to a
