Description. Based on holotype female, 9.3 mm, AM P36906 View Materials . Head much deeper than long, anterior margin with notch extended into a slit; rostrum present, cone-shaped; eye present, ventrally tapered. Antenna 1 peduncular article 1 not ball-shaped proximally, distal margin with small medial spine; peduncular article 2 medium length; flagellum without callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1, without calceoli. Mouthpart bundle subconical. Epistome/upper lip with broad mid-anterior bulge (lateral view). Mandible lacinia mobilis a stemmed, distally-cusped blade; accessory setal row with intermediate setae; palp article 2 with 2 posterodistal setae, article 3 without A3-seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus subequal in length to propodus; propodus, posterior margin without robust setae. Gnathopod 2 palm acute, with no lateral robust setae, 4 medial robust setae. Pereopods 3 and 4 merus and carpus without setal fringe. Pereopod 4 coxa with anterior margin slightly obtuse, posterior margin rounded, anteroventral corner rounded. Pereopods 5–7 with distal articles elongate, dactyli long and slender. Pereopod 5 basis expanded posteriorly, rounded with sloping posteroproximal shoulder. Pereopod 7 basis rounded posteriorly, posteroventral corner rounded, posteroventral margin straight.

Epimeron 3 posterior margin smooth, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 10 robust setae; outer ramus without large spines between robust setae. Uropod 2 inner ramus moderately constricted. Uropod 3 rami lanceolate; without plumose setae; outer ramus 1-articulate. Telson moderately cleft (about 32 %).

Etymology. The specific name is taken from the research vessel Kimbla, which collected the type material.

Remarks. Most species of Bamarooka ( B. bathycephala , B. dinjerra , B. endota and B. kimbla ) have ventrally tapered eyes. Bamarooka kimbla differs from all of these species in the cone-shaped rostrum.

Distribution. Northeastern Australia; 150 m depth.
