Remarks. Leipsuropus is a monotypic genus recognizable 
by the coalesced pereonites 6-7. Leipsuropus parasiticus 
can be identified from other Australian podocerid species 
by the distinctive dorsoventrally flattened body, which when 
viewed dorsally appears subovoid. 
Distribution. Australia. New South Wales. Port Jackson 
(Haswell, 1879); Botany Bay; Port Stephens; Ulladulla 
(current study). Victoria. Western Port (J. L. Barnard & 
Drummond, 1981). 
Podocerus Leach, 1814 
Podocerus Leach, 1814: 433.—Stebbing, 1906: 700.—J. L. 
Barnard, 1970: 237.—Lincoln, 1979: 570.—Barnard & 
Karaman, 1991: 664. (Type species Podocerus variegatus 
Leach, 1814 by monotypy). 
Platophium Dana, 1852:309.—Dana, 1853:837 (Type species 
Platophium brasiliense Dana, 1853 by monotypy). 
Dexiocerella Haswell, 1885: 107 (Type species Cyrtophium 
dentatum Haswell, 1879 subsequent selection of Barnard 
& Karaman, 1991). 
Diagnosis. Amended after Laubitz, 1984: Pereon depressed, 
with 5-7 segments; urosome of 3 segments. Antennae 1 
accessory flagellum present; maxilla 1 inner plate reduced 
and non-setose or absent, outer plate with 9 spines; maxilla 
2 without facial setae; maxilliped palp 4 blunt; brood plates 
on pereopods 2-4 or 2-5; uropod 2 uniramus or biramus; 
uropod 3 without rami. 
Remarks. The generic description of the uropod 2 is 
expanded to include a uniramus aswell as biramus character 
state, based on the inclusion of P. tamoshanta sp. nov. 
Podocerus akanthius sp. nov.
