One record NE of North Island, 2500 m, and one record W of South Island. Etymology. Brucerolis brandtae is named for Professor Angelika Brandt, who studied the phylogeny of serolids and described new serolid genera and species. Remarks. The large size of males and females (up to 40 and 35 mm respectively) of Brucerolis brandtae and the wide anterolateral head lobes with a straight or convex anterior margin are useful characters for identifying this species. Like B. hurleyi and B. osheai, the anterior transverse ridge on the head of B. brandtae has a strongly acute, posteriorly curved dorsal projection immediately adjacent to the insertion of antenna 1 on both sides.	en	Storey, Melissa J., Poore, Gary C.

038EC15CFFD1663BFF5EFC47FB7FFE78.taxon	distribution	Distribution. The type locality and only confirmed record is at 3612 m depth, from a bottom of diatom ooze, 62 ° 26 ' S, 95 ° 44 ' E, Southern Indian Ocean. Remarks. Brucerolis bromleyana can be identified by the small acute projection on the anterolateral margins of pereonite 1, the emarginate tips of epimera 2 and 3 and the short, concave palm on the male pereopod 2 propodus. The only other species with a small acute projection on the anterolateral margins of pereonite 1 are B. maryannae and B. macdonnellae, both from the South Atlantic. Brucerolis maryannae can be distinguished from B. bromleyana by the serrulate anterior margin of the head and pereonite 1 and by the rounded posterior margin of the pleotelson (that of B. bromleyana is concave). Brucerolis macdonnellae also has a rounded posterior margin of the pleotelson and also differs from B. bromleyana by the acute tips of epimera 2 and 3. Poore and Brandt (1997: 15, fig. 3) illustrated a male of “ Acutiserolis sp. ” that shares with these three species an acute projection on the margin of pereonite 1. It differed in a more erect submarginal ridge and more elongate propodus on pereopod 2 and may well represent another similar species of Brucerolis close to or in the Southern Ocean.	en	Storey, Melissa J., Poore, Gary C.

Brucerolis cidaris is diagnosed by its small size, emarginate tips of epimera 2 and 3 and pock-marked anterolateral region of pereonite 1. Brucerolis hurleyi and B. osheai are similar to B. cidaris but both have a covering of long setules on the lower margin of the male pereopod 2, a dorsal curved acute process on the anterior margin of the head and acute tips of epimera 2 and 3.	en	Storey, Melissa J., Poore, Gary C.

This species is named for its distribution on the Lord Howe Rise. Remarks. Brucerolis howensis is most similar to B. nowra (Fig. 1 f), B. victoriensis and B. cidaris, all four with emarginate epimera apices. Brucerolis howensis can be distinguished by the combination of the weak projection of the anterolateral lobes of the head, the concave anterior margin and lack of submarginal sculpture on the dorsal surface of pereonite 1 and male epimeron 3 barely reaching (female epimeron 3 not reaching) the posterior margin of the telson.	en	Storey, Melissa J., Poore, Gary C.

Size. Adult male and female body length 17 − 30 mm. Distribution. New Zealand, western Cook Strait to eastern slope of New Zealand, Chatham Rise, Bounty Plateau, Campbell Plateau, 40 ° ' S − 53 ° S, 168 ° E − 176 ° W, 315 − 1024 m. Etymology. Brucerolis hurleyi is named for Dr Desmond E. Hurley, who first noted morphological variation within what he called Serolis bromleyana around New Zealand. Remarks. Brucerolis hurleyi and B. osheai are similar, both with acute epimera apices, similarly shaped anterior head margin (although in B. hurleyi, the anterolateral corners of head are not continuous with anterior margin of pereonite 1), setose lower margins of the ischium, merus and carpus of male pereopod 2 and setulose carpus and propodus of male pereopod 7. Brucerolis hurleyi can be recognised by: strongly convex propodus palm of male pereopod 2; ventral coxal plates with an anteriorly projecting, circular tubercle on the anterior margin adjacent to the midline suture; lack of setules on the merus of the male pereopod 7; and absence of the colour pattern seen in most individuals of B. osheai. The species is unusual in the possession on antenna 1 flagellum articles of a row of denticles. One unusual adult male specimen (NIWA stn D 9 DR, SE Macquarie Island) has an appendix masculina on pleopods 2 and 3 on both sides.	en	Storey, Melissa J., Poore, Gary C. B.

South Atlantic, western side of South Sandwich island arc between Visokoi and Lesokov Island, 56 ° 43 ' S, 27 ° 41 ' W, 2741 m (only type known). Remarks. Pereonite 1 of Brucerolis macdonnellae and B. bromleyana has an acute projection on the anterolateral margin and prominent submarginal and transverse ridges on the dorsal surface. In as far as the description of the damaged material allows, Brucerolis macdonnellae can be differentiated by the acute tips of epimera 2 and 3, shorter epimeron 3 and shorter, more curved coxal dorsal plates.	en	Storey, Melissa J., Poore, Gary C.

038EC15CFFC7662DFF5EFF52FD88FC95.taxon	distribution	Distribution. South Atlantic, continental rise S of Staten I., northwest Scotia Sea, 55 ° 31.2 ' S, 64 ° 07.5 ' W, 3839 m (only type known). Remarks. Brucerolis maryannae is the only species in the genus to have a serrulate anterior margin of the head and pereonite 1. It shares with B. bromleyana the acute projection on the anterolateral margin of pereonite 1 and emarginate tips of epimera 2 and 3. These features and the long coxal plates and epimera suggest a relationship to this species. Menzies’s (1962) illustration would indicate that the coxal keys and intervening apertures are absent. It may be possible that the keys are not visible in dorsal view on such a small female (18.8 mm) or that the drawing is incorrect.	en	Storey, Melissa J., Poore, Gary C. B.

For Steve O’Shea, who arranged for the loan of the material from New Zealand on which much of this work is based. Remarks. Brucerolis osheai is similar to B. hurleyi but may be distinguished by a more pronounced median posterior tubercle on the head, the anterolateral corners of head continuous with anterior margin of pereonite 1, a generally smaller body with characteristic pigment spots on the antennae, head and pereonites, a setulate lower margin of the male pereopod 7 merus, carpus and propodus and ridged ventral coxae.	en	Storey, Melissa J., Poore, Gary C.

Head, anterolateral margins concave, lateral corners acute and projecting anteriorly (slightly); width between anterolateral corners as wide as maximum span between lateral margins of eyes; head without paired processes on transverse ridge at bases of antennae 1, with obsolete paired tubercles between eyes, with small, blunt median posterior tubercle, with obscure lobes lateral to median posterior tubercle. Pereonite 1 lateral margin anteriorly convex, straight over most of length, lateral margin upturned over anterior half, sharply crested, with sinuous high rounded oblique ridge more or less parallel to margin, separated from it by a shallow trough occupying about one-quarter of width, dorsal surface with obsolete oblique-transverse ridge reaching sinuous ridge. Coxal dorsal plate 2 slightly more than half as long as pereonal tergite 2 width (following plates increasing in length); plate 4 1.5 times as long as half pereonal tergite 4 width; plate 6 extending beyond tip of pleotelson by 2.1 times middorsal length of pleotelson, the pair diverging and then converging slightly apically, curving evenly; pleonal epimeron 2 1.9 times length of pleotelson; pleonal epimeron 3 1.1 times length of pleotelson; pleonal epimera 2 and 3 with acute apices. Ventral coxal plates 2 – 4 with transverse ridges on mesial, anterior and posterior margins outlining a transverse depression. Antenna 1 peduncle articles 3 + 4 1.9 times as long as article 2 (anterior margin); flagellum of about 50 articles. Antenna 2 peduncle article 5 similar length to article 4; flagellum of 18 articles. Pereopod 1 propodus 2.2 times as long as greatest width. Pereopod 2 palm dorsal length 1.9 times greatest width, with short right-angled heel, convex palm with 15 robust setae arranged in oval (several shorter than others). Pereopod 7 carpus 4.7 times as long as greatest width; propodus 5.6 times as long as greatest width, propodus tapering from near base, lower margin straight; dactylus curved, 0.4 times as long as propodus. Pleopod 2 endopod with convex distal margin, sharply tapering to base of appendix masculina. Uropodal exopod 1 length of endopod. Female. Pereonite 1, lateral margin of female convex anteriorly, with distinct step-like interruption and straight posteriorly. Coxal dorsal plate 2 of female 0.6 times as long as half pereonal tergite 2 width; plate 4 of female as long as half pereonal tergite 4 width (following plates increasing in length); plate 6 of female extending beyond tip of pleotelson by 1.9 times middorsal length of pleotelson, the pair diverging and then converging slightly apically, curving evenly. Size. Adult male and female body length: 28 − 38 mm. Distribution. Australia, eastern and southern continental slope of NSW, Vic., Tas. and eastern SA, 34 ° 42 ' S – 41 ° 25 ' S, 1073 − 2010 m. Etymology. For Victoria, the Australian state where most specimens have been taken. Remarks. The submarginal anterolateral groove on pereonite 1, defined by its upturned margin and sharp inner ridge identify Brucerolis victoriensis. The species shares with the non-New Zealand species (B. howensis and B. cidaris) emarginate epimera and absence of projections on the transverse ridge of the head.	en	Storey, Melissa J., Poore, Gary C.
