Emended diagnosis

Head, rostrum absent, eyes absent or poorly developed. Antennae slender; antenna l peduncular articles 1 – 2 long, article 3 short, accessory flagellum 2-articulated; antenna 2 shorter than 1. Mandibular palp long, with 3 articles; article 2 weakly setose; article 3 slightly falcate, subequal to or longer than article 2, with marginal and terminal setae. Lower lip without inner lobes. Maxilla 1, inner plate triangular, setose medially; outer plate with serrate robust setae distally; palp 2-articulated, with apical robust setae. Maxilla 2, inner plate with medial setae and oblique facial row of setae. Coxae medium-sized, coxa 4 unlobed. Gnathopod 1 small, subchelate; carpus unlobed; propodus shorter than carpus, palm short, almost transverse. Male gnathopod 2 enlarged, subchelate; carpus unlobed, setose posteriorly; propodus long, posterior margin setose, palm very oblique. Female gnathopod 2 feeble, almost simple; propodus smaller than that of male. Pereopods 3 – 7 slender, bases of pereopods 5 – 7 relatively expanded. Uropods biramous; uropod 2 peduncle with mediodistal comb of setae [not recognized in Dulzura melitaformis ( Ledoyer, 1979)   ]; uropod 3 elongate, parviramous [inner ramus much shorter than outer ramus and lacking medial armaments ( Barnard and Barnard 1983)], outer ramus with 2 articles, article 2 less than 20% as long as article l, inner ramus shorter than half length of outer. Telson of ordinary length, cleft, apical end with robust setae.

Remarks

Springthorpe and Lowry (2009) synonymized Protohadzia   with Dulzura   for the reason that distinctions between them have never been strong. However, Lowry and Myers (2013) left Protohadzia   unsynonymized.
