Description. Based on holotype female, 7.5 mm, NMV J13937 View Materials . Head much deeper than long, anterior margin with notch extended into a slit; rostrum present, anteriorly truncated; eye present, ventrally tapered. Antenna 1 peduncular article 1 not ball-shaped proximally, distal margin without a 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 1 posterodistal seta, article 3 without A3-seta. Maxilliped outer plate with distal margin smooth, medial margin without notch.

Gnathopod 1 carpus subequal in length to propodus (0.9×); propodus, posterior margin without robust setae. Gnathopod 2 palm slightly acute, with no lateral robust setae, 3 medial robust setae. Pereopods 3 and 4 merus and

0.1 mm; remainder represent 0.2 mm.

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. Pereopod 7 basis rounded posteriorly, posteroventral corner rounded, posteroventral margin curved.

Epimeron 3 posterior margin smooth, with notch well above rounded posteroventral corner. Uropod 1 peduncle dorsolateral margin with 8 robust setae; outer ramus without large spines between robust setae. Uropod 2 inner ramus slightly   constricted. Uropod 3 rami lanceolate; without plumose setae; outer ramus 1-articulate. Telson slightly cleft   (about 28%).

Male (sexually dimorphic characters). Based on paratype male, 5.9 mm, NMV J13938 View Materials . Antenna 1 flagellum with callynophore. Antenna 2 flagellum with calceoli. Mandible palp article 2 with 10 posterodistal setae. Gnathopod 2 palm with 1 medial robust seta   .

Etymology. The specific name is an Australian Aboriginal word meaning “beautiful”.

Remarks. Most species of Bamarooka   ( B. bathycephala   , B. dinjerra   , B. endota   and B. kimbla   ) have ventrally tapered eyes. Bamarooka endota   and B. dinjerra   are very similar. They differ in the basis of pereopod 5, which is almost round in B. endota   and has a sloped proximal posterior shoulder in B. dinjerra   .

Although B. endota   and B. bathycephala   both occur in Bass Strait in similar depth range, the two species have not been taken in the same samples. Bamarooka bathycephala   is found most often on clean sand bottoms whereas B. endota   is most often found on muddy sand.

Habitat. Bamarooka endota   occurs on fine and coarse sediments.

Distribution. Southeastern Australia, from central NSW to Bass Strait; 40–175 m depth.
