FIGURE 10. Podoprionides moonamoona sp. nov. Holotype female, AM P.69034. Type locality . Jervis Bay , New South Wales , Australia , 35°03.5'S 150°41'E , 4.5 m depth . Etymology . The species name refers to the type locality. Diagnostic description . Antenna 1 callynophore absent; calceoli absent in male. Eyes present. Mouthpart bundle subconical. Mandible left incisor with straight margin, minutely serrate, right with strongly convex margin, smooth; lacinia mobilis absent; molar absent; palp attached extremely proximally, article 2 longer than article 3. Maxilla 1 outer plate with 9 setal teeth in a 6/3 crown arrangement, outer row with cusps in 1 row; palp apical margin serrate, without apical setae. Maxilliped palp 3-articulate. Gnathopod 1 chelate; ischium short; carpus posterior margin produced into broad triangular lobe; propodus subquadrate, proximal margin produced into strong posteroproximal lobe, palm smooth with a small central bump, posterodistal corner produced into long acute spine, without robust setae. Gnathopod 2 minutely subchelate; carpus much longer than propodus (about 2 x); palm transverse. Pereopod 4 coxa posteroproximal excavation small. Pereopods 5–7 basis with strongly serrate posterior margin; dactylus short, slender. Epimeron 3 posterior margin smooth, posteroventral corner rounded. Uropod 3 peduncle subequal to inner ramus, without distoventral spur; inner ramus shorter than outer ramus; outer ramus 2-articulate, article 2 long; rami without robust setae, without plumose setae. Telson about as long as broad, moderately cleft (about 56%), without dorsal robust setae. Male. Same as female except: Gnathopod 1 palm with large irregular central protrusion; dactylus with irregular protrusion on inner margin. Pereopod 7 merus anterodistal corner with single very large, distally complex robust seta. Remarks. Podoprionides moonamoona differs from both P. incerta and P. akantha in the absence of a callynophore, the ornamentation of gnathopod 1 palm, and the peduncle of uropod 3 subequal to the rami, which is based on our examination of the orginal type of P. incerta .
