Mx1 gnathobase with 9 setae, second and third internal lobes with 2 and 3 setae respectively, protopodite near endopodite base with 4 setae.
Sensory appendage of Mxp club-shaped.
Caudal rami short, rounded at the tip, apical setae elongated.
External lobe on the endopodite of P1 much better developed than in other species of genus. P1 with seta near endopodite base.
Male.
Body stout, smoothly rounded in its anterior part. Posterior corners of the last thoracic segment reduced to obtuse angles, and not directed backwards as in females. 2nd abdominal segment slightly longer than the 1st, anal segment very short.
A1 23-segmented, nearly as long as cephalothorax.
Mx1 with reduced lobes, without setae and chewing spines
Mxp significantly weaker than in females, protopodite significantly thinner, without any setae.
P1-P4 as in female.
P5 with 2-segmented protopodite. Left endopodite 2-segmented, right endopodite one-segmented; left exopodite 3-segmented, its last segment short; right exopodite 2-segmented, distal part of the 2nd exopodal segment prolonged, curved in its terminal part and plumose.
