PARATYPES: AM P60468, 122 specimens (33 and ♀♀), 3–5 mm, 34°32.09'S 151°12.55'E, 200 m (NSW-797), off Wollongong , New South Wales, Australia, 07 May 1993. Collector: P. Freewater & party on MV “Robin E” ( SEAS project, trap 1, transect 2).

Distribution. Known only from the type locality.

Diagnosis. Pleonites dorsally smooth. Antenna 1 flagellum with 4 articles. Antenna 2 peduncle article 4 shorter than article 5. Epistome produced laterally, epistomal plate present. Labrum shorter than broad, both lobes reduced. Mandibular incisor smooth, transverse. Lacinia mobilis reduced, not expanded laterally. Maxilla 1 outer plate with ST in two parallel rows, palp uni-articulate. Maxilla 2 outer plate not gaping and geniculate. Coxa 4 distally broad. Pereopod 6 basis expanded. Uropod 3 outer ramus 2- articulate. Articulation between urosomites 2 and 3 absent. Telson about as long as broad, rounded, cleft.

Description. Rostrum reduced, inconspicuous. Antenna 1 about as long as antenna 2; accessory flagellum article 2 present. Antenna 2 peduncle articles 3–5 longer than flagellum; article 3 short, about as long as broad. Epistome rectangular, with a long ridge on each side; epistomal plate produced into a small elongate medial ridge covering the entire epistome. Maxilla 1 palp reaching above the apex of outer plate; outer plate distally subrectangular; ST first row with 6 setae (ST1–5, ST7); ST 6 absent; gap between ST 5 and ST 7 present; ST A–C present, part of second row; inner plate with pappose setae. Maxilla 2 ordinary; outer plate setae distally simple; inner plate setae row A covering the entire margin, clearly separated from row B; row A setae pappopectinate; row B setae proximally pappose, distally with cusps present; row C present; row D absent. Maxilliped palp 4-articulate; article 2 distally unproduced; dactylus distally simple, pointed; inner plate not exceeding base of palp article 1; 2 nodular setae; medial setae-row transverse with pectinate setae; distal setae-row present; inner setaerow not; outer plate with outer setae-row marginal, setae long robust; inner setae-row reduced with short and simple setae; row parallel but not appressed to outer setae-row; distal setae-group absent. Labium distally broad, oval. Coxae and bases on the pereopods covered with setae; setae very short. Coxae1–3 contiguous. Pereopod 1 coxa deeper than basis; propodus distally narrowing. Pereopod 2 general appearance like pereopod 1; ischium not elongate, distal posterior margin with plumose setae; propodus distally narrowing, palm absent. Pereopod 4 basis posterior margin with long setae, plumose setae on distal posterior margin; ischium with plumose setae on distal posterior margin. Pereopod 6 basis more than twice as broad as basis on pereopod 5, medially with a row of long plumose setae. Pereopod 7 basis anterior margin straight, distally rounded; medial row ofsetae present, setae short and robust. Oostegites on pereopod 2–5, gills on pereopods 2–7.

Uropods: 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 longer than inner. Telson shorter than peduncle uropod 3; submarginal setae on apex of each lobe present.

Male. Pereopod 2 propodus larger in males than in females, urosome ordinary (similar to females).

Etymology. Named after Dr Traudl Krapp (Bonn), great friend and indefatigable amphipod worker.
