Paralibrotus Stephensen, 1923 (Fig. 28) Paralibrotus Stephensen, 1923: 61.—J.L. Barnard, 1969: 356.— Barnard & Karaman, 1991: 512. Type species. Paralibrotus setosus Stephensen, 1923, monotypy. Included species. Paralibrotus includes 1 species: P. setosus Stephensen, 1923 Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum forming cap covering callynophore. Antenna 2 without brush setae. Mandible molar a weakly setose flap. Maxilla 1 outer plate with 8 well developed setal-teeth in modified 7/4 crown . Maxilla 2 inner plate significantly shorter than outer plate. Gnathopod 1 simple coxa 1 large, about as long as coxa 2, subrectangular with straight anterior margin ischium short (length less than 2 × breadth); carpus short (length 1 to 2 × breadth); propodus margins tapering distally. Uropod 2 inner ramus not constricted. Telson entire . Remarks. Paralibrotus has a number of highly derived characters which make it difficult to characterize. Based on the gnathopod 1 large coxa and short carpus, and an entire telson it is most similar to Onisimus . It differs mainly in the reduced flap-like molar and the simple first gnathopod. : Published as part of Lowry, J. K. & Kilgallen, N.
