d, e) massive, characteristic in shape. Basal segment of protopodite large, oblong, juxtaposing basis and originating at the same level as the basis. Dentate lobe shorter than the rounded inner lobe and with straight or somewhat convex free margin, carrying five or six teeth in a row. Basis roughly conical, extending well beyond the level of dentate lobe and with one subapical seta. Epipodite (external lobe) conical and arising from the basis. Exopodite curved, sharply bending backward and with a row of apical denticles. Endopodite rectangular, with one subapical and two unequal apical setae.
