Type locality. Southeast of Broken Bay , NSW, Australia, Tasman Sea, 33°37'S 152°04'E GoogleMaps to 33°39'S 152°02'E, 896– 924 m depth.

Description. Based on holotype female, 11.5 mm, AM P36868 View Materials . Head much deeper than long, anterior margin with notch extended into a slit; rostrum present, anteriorly rounded; eye present or apparently absent, elongate, reniform. Antenna 1 peduncular article 1 ball-shaped proximally (slightly), distal margin with large medial spine; peduncular article 2 long, length 2× breadth; flagellum without callynophore, calceoli absent. Antenna 2 flagellum about as long as that of antenna 1. Mouthpart bundle subquadrate. Mandible lacinia mobilis a stemmed distolaterally cusped blade; accessory setal row with intermediate setae; palp article 2 without posterodistal setae, article 3 without A3-seta. Maxilliped outer plate with distal margin serrate (minutely), medial margin without notch.

Gnathopod 1 carpus longer than propodus (1.3×); propodus, posterior margin with robust setae. Gnathopod 2 palm acute, with 1 lateral robust seta, 1 medial robust seta. Pereopods 3 and 4 merus and carpus without setal fringe. Pereopod 4 coxa with anterior margin slightly obtuse, posterior margin straight, anteroventral corner rounded. Pereopods 5–7 with distal articles elongate, dactyls short and slender. Pereopod 5 basis expanded posteriorly, rounded. Pereopod 7 basis subrectangular, posteroventral corner subquadrate, posteroventral margin straight.

Epimeron 3 posterior margin smooth, with notch immediately above acute posteroventral corner. Uropod 1 peduncle dorsolateral margin with 12 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 2-articulate. Telson moderately cleft (about 35%).

Etymology. Named for the former New South Wales Fisheries Research Vessel, the FRV Kapala , which made many valuable collections of marine invertebrates off the coast of New South Wales.

Remarks. All three Indo-West Pacific species of Bathyamaryllis are very similar. Bathyamaryllis kapala can be distinguished from B. perezii by the shape of coxa 4, which has a slightly obtuse anterior margin and a straight posterior margin in B. kapala , but subparallel anterior and posterior margins in B. perezii . It can be distinguished from B. ouvea by the shape of the rostrum, which is rounded in B. kapala and truncated in B. ouvea .

Habitat. Bathyamaryllis kapala has been collected from sand and mud bottoms but its habitat is generally not known.

Distribution. Southeastern Australia, Tasman Sea; 896– 1840 m depth.
