 Description   
Length of females 3±4 mm, males unknown.  
Rostrum very small.  
Antennae short. Antenna 1 longer than antenna 2; ¯agellum four-articulate; accessory ¯agellum article 2 present. Antenna 2 peduncle (articles 3±5) longer than ¯agellum; article 3 short, about as long as broad; article 4 as long as article 5.  
Epistome produced laterally, rectangular, with a long ridge on each side; epistomal plate (medial keel) produced into a small elongate medial ridge covering the entire epistome.  
Mouthparts not elongate or pointed.  
Mandible incisor transverse, smooth; left lacinia mobilis present, reduced, laterally straight, not conical.  
Maxilla 1 palp uni-articulate, rectangular, apex reaching above the apex of outer plate; outer plate distally rounded; ST in two parallel rows, ®rst marginal and second submarginal, ST ®rst row with six setae (ST1±5, ST7), ST 1 ordinary (similar to ST 2±4), gap between ST 5 and ST 7; ST A±C present, part of second row; inner plate without a well developed shoulder, setae pappose.  
Maxilla 2 ordinary; outer plate setae distally without hooks or cleft; inner plate setae row A covering the entire margin, clearly separated from row B, row A setae pappose and pappopectinate, ®rst three or four setae diOEerentiated from the other setae (weakly pappopectinate); row B setae proximally pappose, distally with cusps; row C present; row D absent.  
Maxilliped palp four-articulate; article 2 distally unproduced; dactylus distally simple (pointed); inner plate not exceeding base of palp article 3, with three nodular setae; medial setae-row present, reduced to one or two setae but diOEerentiated from distal row, transverse, setae simple; distal setae-row present; inner setae-row present, row not reduced (more than two setae), setae not conspicuously large; outer plate outer setae-row present, marginal, setae attached normally, long, robust, straight; inner setae-row present but strongly reduced, setae short, simple, slender, parallel but not appressed to outer setae-row; distal setae-group absent.  
Labrum weakly elongate; lobes asymmetrical, right lobe not reduced, left lobe reduced.  
Labium distally broad, oval.  
Coxal plates and basis on the pereopods smooth.  
Coxae 1±3 contiguous.  
Pereopod 1 coxal plate not as deep as basis; propodus subovate.  
Pereopod 2 longer and thinner than pereopod 1; ischium elongate, ratio length:- breadth exceeding 1.5; distal posterior margin with plumose setae; propodus subovate; palm absent.  
Pereopod 4 coxa posteroventral lobe large, reaching about the base of pereon segment 7; basis anterior margin without long setae, posterior margin with long setae, plumose setae on distal anterior margin, no plumose setae on distal posterior margin; ischium with plumose setae on posterior distal margin.  
Pereopod 6 basis posteriorly expanded, expansion conspicuous, rounded posteriorly, with a row of long plumose setae.  
Pereopod 7 basis anterior margin straight, distally rounded; with a medial row of setae, setae short and robust.  
Oostegites on pereopods 3±5. Gills on pereopods 2±6.  
Pleonites 1±3 dorsally smooth.  
Urosome: articulation present between urosome segments 2 and 3. Uropod 1 peduncle longer than rami, outer ramus longer than inner. Uropod 2 peduncle longer than rami, outer ramus longer than inner. Uropod 3 peduncle longer than half the length of rami, outer ramus two-articulate, outer ramus longer than inner.  
Telson as long as broad; shorter than uropod 3 peduncle, cleft, apically rounded, submarginal setae on apex of each lobe.  
 Males. Unknown.   
 Etymology   
The present species is named after the locality where the species was collected; Wollongong, New South Wales.  
 Remarks   
 The present species is separated from all of its congeners by the relatively long and strongly asymmetric labrum. See also Remarks under A. lowryi.
