Hughes: southern Australian podocerid amphipods 
75 
ventromedial spine; outer ramus about half the length of 
inner ramus. Uropod 3 uniramus, rami without apical setae. 
Telson apically rounded, dorsal lobe absent, without lateral 
or apical setae. 
Female (sexually dimorphic characters) based on female 
specimen, 3.6 mm, AM P.86216. 
Gnathopod 1 basis without anterodistal robust setae; 
carpus rectolinear, twice as long as broad; propodus 
rectolinear, twice as long as broad, palm margin smooth, 
weakly convex, without palm defining margin or robust setae; 
dactylus posterior margin with 3 serrate teeth. Gnathopod 
2 basis anterior margin subquadrate, without robust setae; 
merus lobes 1.3 times as long as broad, anterior margin 
apically subacute, without robust setae; propodus spherical, 
1.2 times as long as broad, anterior margin with clusters of 
long slender setae, palm convex, smooth, about half length 
of propodus, without distal shelf, palm defined by corner 
with 3 robust setae. 
Remarks. Cyrtophium minutum is superficially similar 
to another Australian species Podocerus lobatus in the 
male gnathopod 1 propodus palm without robust setae and 
gnathopod 2 propodus palm sculpting with distal and palm 
defining tooth. In C. minutum antenna 1 is subequal in length 
to antenna 2, while antenna 1 is shorter than antenna 2 in 
P. lobatus. Cyrtophium minutum has a body plan which is 
tending towards dorsoventrally flattened. 
Distribution. Australia. New South Wales. Port Jackson 
(Haswell, 1879), Port Stephens, Ulladulla (current study). 
Victoria. Gabo Island (current study).
