Description. Based on holotype female, 3.3 mm, AM P.69443. Head lateral cephalic lobe margins straight dorsally, ventrally sinusoidal, apically acute. Antenna 1 accessory flagellum not forming operculum, terminal article not offset; primary flagellum with strong 2-field callynophore, robust setae absent from proximal articles; calceoli absent. Antenna 2 peduncular article 3 short; articles 3 to 5 not enlarged; flagellum short, calceoli absent. Labrum epistome/upper lip separate; epistome produced equally with upper lip, slightly concave; upper lip not produced. Mandible molar with reduced column and reduced triturating surface; palp attached midway. Maxilla 1 outer plate setal-tooth 7 present, left and right symmetrical, cuspidate distally along inner margin; palp distal margin with apical robust setae. Maxilliped basis without recurved hook.
Pereonites 1–7 dorsally smooth. Gnathopod 1 subchelate; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; basis moderately setose along anterior margin; ischium short; carpus long, longer than propodus, without posterior lobe; propodus small, margins subparallel, sparsely setose along posterior margin, palm moderately acute, entire, straight. Gnathopod 2 propodus palm transverse. Pereopod 5 basis longer than broad, not posteroproximally excavate, posterior margin not serrate. Pereopod 7 basis posterodistally produced, not reaching merus; not posterodistally excavate.
Pleonites 1–3 without mid-dorsal carina, not produced dorsodistally. Epimeron 3 posterior margin smooth, posteroventral corner subquadrate. Urosomite 1 with slight notch. Uropod 3 peduncle without dorsolateral flange; inner and outer rami well developed, outer ramus article 2 short, with plumose setae on both rami.
