Description HEAD + ROSTRUM. Weakly curved in lateral view. ROSTRUM. In lateral view short and very broad, reaching about 0.6 of article 1 of peduncle of antenna 1, anteriorly weakly convex and ventrally straight, blunt-tipped. EYES. Huge, broadly elliptic. PEREION–PLEOSOME TOOTH PATTERN. Pereionites 1–7 and pleonites 1–2 totally smooth; pleonite 3 missing. COXAE 1–3. Tip broadly rounded. COXA 4. Fairly narrow; anterodorsal border straight; anteroventral border slightly convex, these two borders being joined by very broad rounded convexity, which is distinctly projecting forward (anterior corner and anteroventral border forming a regular curve, without discontinuity); anterodorsal border 1.4 x as long as anteroventral border; ventral corner bluntly and obtusely angulate; posteroventral border nearly straight. COXA 5. Broad, posteroventral corner very broadly rounded in lateral view. COXA 6. Posterior border weakly convex; posteroventral corner very broadly rounded. COXA 7. Posterior border nearly straight (inconspicuously concave); posteroventral corner broadly rounded. EPIMERAL PLATES 1–2. Posteroventral angle very obtusely rounded in plate 1 (without any trace of tooth), produced into a small tooth in plate 2. UROSOME. Missing. GNATHOPODS 1–2. Carpus and propodus short and very broad; propodus not expanding distally, palm not reduced. PEREIOPOD 6. Basis of normal width, with posteroproximal process absent, with posterodistal corner rounded or very bluntly angulate. PEREIOPOD 7.
