Protopodal part flattened joined by plate-like, intercoxal sclerite forming apron, ornamented with marginal membrane posteriorly and along lateral margin anterior to exopod; bearing inner plumose seta at junction with intercoxal plate, and outer plumose seta dorsal to base of exopod; sensillae located adjacent to inner coxal seta and adjacent to origin of endopod; with corrugated expansion anterior to lateral margin membrane. Exopod 3- segmented; first segment armed with almost straight outer claw directed over ventral surface of ramus, lacking inner seta; second segment with slender outer spine and inner plumose seta; third with 7 setal elements (3 outer spiniform elements and 4 inner plumose setae); outer margins of segments 2 and 3 ornamented with rows of slender setules. Endopod 2-segmented; first segment forming flap-like velum ornamented with row of fine setules along free margin, and with inner plumose seta; compound distal segment with expanded and setulate lateral margin, bearing 6 setal elements increasing in length from outermost to innermost, ornamented with 2 sensillae on dorsal surface.

When sorting these caligids freshly caught, they could be recognised by the distinctive exopod of leg 3: the second segment is relatively long (compared to the first and third segments) and the outer spine on the first segment is linear and extends the entire length of the second segment.
