Side-plates mucli shallower than the segments, 4*'^ rather broader than 

 deep, only in part overlapping 5*^. Peraeon segment 1 as long as 2*^ and 3*^ 

 corabiued. Pleon much smallfer than peraeon. Pleon segment 3, postero-lateral 

 angles produced, scarcely acute. Eyes wanting. Antennae not very unequal, 

 flagella many-jointed. Antenna 1, l**"^ Joint of flagellum and accessory flagellum 

 long. Antenna 2, ultimate Joint of peduncle longer than penultimate, flagellum 

 shorter than in Parandania (p. 95). Mandible widened at the middle, cutting 

 edge broad, straight, smooth, accessory plate of right mandible small, Lower 

 lip, lobes widely, not deeply, dehiscent, broadly rounded, without mandibular
