Head, lateral cephalic lobes subtriangular, apically subacute. Antenna 1 peduncular article 1 without anterodistal lobe; accessory flagellum not forming cap, 5-articulate, terminal article not offset; primary flagellum with strong 1-field callynophore; robust setae absent from proximal articles; calceoli absent. Antenna 2 peduncular article 3 short, articles 3 to 5 not enlarged, brush setae absent; flagellum short; calceoli absent. Labrum, epistome and upper lip separate; epistome less produced than upper lip, straight; upper lip produced, strongly acute apically. Mandible incisor large, left and right symmetrical; molar with asymmetrically reduced column, proximally setose, distally triturating; palp attached about midway, article 2 margins subparallel, article 3 blade-like. Maxilla 1outer plate setal-tooth 7 present, left and right symmetrical, cuspidate distally along inner margin; palp distal margin with apical robust setae. Maxilliped outer plate with one slender and one broad apical robust setae. Gnathopod 1 simple; coxa large, about as long as coxa 2, subrectangular with straight anterior margin; basis moderately to densely setose along anterior margin; ischium long (length 2 × to 4 × breadth); carpus long (length 2 to 4 × breadth), slightly longer than propodus, without posterior lobe; propodus margins tapering distally; dactylus simple. Gnathopod 2 propodus palm transverse, dactylus distinctly shorter than palm. Pereopod 4 coxa with a well-developed posteroventral lobe. Pereopod 5 coxa without distinct lateral ridge; basis about as long as broad, posterior margin weakly or not serrate. Pereopod 7 basis posterodistally produced less than halfway along merus. Pleonite 3 without mid-dorsal carina, not produced dorsodistally, posterodorsal margin not produced. Epimeron 3 posterior margin smooth, posteroventral corner acutely produced, forming weak spine. Urosomite 1not projecting over urosomite 2, dorsally rounded. Uropod 2 inner ramus with slight constriction. Uropod 3 peduncle without dorsolateral flange; outer ramus article 2 short, with few plumose setae on inner ramus.  Telson moderately cleft, without dorsal robust setae, with 2 apical robust setae on each lobe.  Sexually dimorphic characters.Based on paratypemale, 10.2 mm, AM P.69044. Antenna 1 primary flagellum with strong 2-field callynophore; robust setae absent from proximal articles; calceoli present. Antenna peduncular brush setae present; calceoli present. Uropod 3 peduncle without dorsolateral flange; outer ramus article 2 short, with plumose setae on both rami.  Depth range. 820–1312 m.   Remarks.  Parschisturella martrudanand  P. simplexappear to be the only species with truly simple first gnathopods. In  Parschisturella martrudanthe cusps on the medial margin of setal-tooth 7 are distal in  P. martrudan(along most of the medial margin in  P. simplex); the gnathopod 2 dactylus is shorter than the palm in  P. martrudan(fitting the palm in  P. simplex); the dorsal margin of urosomite 1 is evenly rounded in  P. martrudan(straight in  P. simplex) and the telson is moderately cleft (deeply cleft in  P. simplex).   Distribution.  Australia. New South Wales: east of Broken Bay; off Wollongong. Tasmania: east of Fortescue Bay; south-south-east of South East Cape, Main Pedra Hill; east-north-east of Cape Tourville. Victoria: south of Point Hicks. 3390865467 1980-12-10 AM, R, T, FRV Australia 910 -33.65 Broken Bay 1204 152.03334 49 50 1 New South Wales holotype 3390865552 1986-02-11 AM, R, T, FRV Australia 854 -33.733334 Port Jackson 1203 151.95 49 50 1 1 New South Wales paratype 3390865525 1986-02-12 AM, R, T, FRV Australia 969 -33.55 Broken Bay 1204 152.18333 49 50 1 1 New South Wales paratype 3390865550 1993-05-06 1993-05-07 1993-05-06 AM, MV P.
