“…The present study shows that Adeuomphalus is certainly related to the latter family and that the radula is a very promising, indicative character for the assignment of skeneiform species into the superfamily Seguenzioidea. Many other deep‐sea genera classified by some authors in Skeneidae have radulae characteristic of seguenziids or eucycline trochids: Akritogyra Warén, 1992; Anekes Bouchet & Warén, 1979, Benthobrookula Clarke, 1961, Granigyra Dall, 1889; Lissotesta Iredale, 1915, Moelleriopsis Bush, 1897, Retigyra Warén, 1989, Trenchia & Vetulonia Dall, 1913 (see Warén & Bouchet 1989; Hickman & McLean 1990; Warén 1992, 1993, 1996; Zelaya et al . 2006).…”

1 Kano, Y. (2008). Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep-sea habitats. -Zoologica Scripta, 37, 1-21. Bayesian and maximum-likelihood phylogenies of Vetigastropoda (Mollusca: Gastropoda) were reconstructed by separate and combined analyses of one mitochondrial (cytochrome oxidase I, COI) and two nuclear (histone H3 and 18S rRNA) gene sequences, with an emphasis on dense taxonomic sampling. More than 70 vetigastropod species belonging to 13 families and 25 subfamilies constituted a robust clade against the two outgroup clades Neomphalina and Cocculinoidea. The phylogenetically controversial family Seguenziidae appeared as a derived Vetigastropoda and constituted a highly supported clade with eucycline and cataegine trochids, and three skeneimorphs (Adeuomphalus, Ventsia and Xyloskenea). These taxa herein treated as the superfamily Seguenzioidea are morphologically very diverse and grouped only by the combination of symplesiomorphies in the shell, radular and head-foot characters. Anatomical peculiarities of Seguenziidae, including the presence of the penis and seminal receptacle, are all apomorphic conditions independently derived from those in higher gastropod clades, as a consequence of the small size and in response to deep-sea habitats, where sperm storage seems to be especially beneficial with low numerical density of individuals and limited periodic cues for gametogenesis. Indeed, internal or semi-internal fertilization has been evolved at least six times in Vetigastropoda, essentially in deep-sea lineages, with weak phylogenetic constraints. Other new vetigastropod clades with high support values include: Turbinidae + Tegulinae (Trochidae) + Skeneidae s.s., Clypeosectidae + Lepetodrilidae, Anatominae (Scissurellidae) + Bathyxylophila (Skeneidae) and Lepetodriloidea + Scissurellidae + Bathyxylophila.

Samples of a soft-bottom community from the continental slope of Campos Basin, off southeast Brazil, were obtained between 2001 and 2003 by the Research Vessel "Astro-Garoupa" with a 0.25 m 2 box corer or by dredging with a Charcot dredge. A total of 177 samples were taken at depths ranging from 700 to 1950 m. Mollusks were present at all of the stations and among Gastropoda the Turridae showed the highest diversity. Within the family Cochlespirinae we found: Leucosyrinx tenoceras (Dall, 1889), L. verrillii (Dall, 1881), expanding the known distribution of the latter species farther south, and L.? subgrundifera (Dall, 1888), which is the first record of this species for the South Atlantic and the shallowest depth at which it has ever been found. Within the family Drilliinae we found Splendrillia centimata (Dall, 1889), also the first record of this species for the South Atlantic and its shallowest depth. Within the subfamily Oenopotinae we describe here three new species in the genus Oenopota Mörch, 1852: O. seraphina n. sp., O. diabula n. sp. and O. carioca n. sp.

“…With optimized sampling technologies (e.g., Agassiz Trawl with an inlet of 500 µm mesh size), a more detailed study of deep sea bottom communities, including organisms of all sizes, is possible. The new material permitted the study of the minute species in Brookula and the newly established genus Benthobrookula (see Zelaya et al 2006), including the comparision of several new species described during the last few decades (Clarke 1961, Dell 1990, Numanami & Okutani 1991, Numanami 1996, Absalão et al 2001, Absalão & Pimenta 2005, Zelaya et al 2006. Absalão et al (2001) and Zelaya et al (2006) illustrated and described all primary types of the species of Brookula from the Southern Atlantic Ocean.…”

However, despite their efforts to clarify the taxonomic status of the described species of Brookula, there is no agreement about the systematic position of the genus within the Vetigastropoda.…”

“…Absalão et al (2001) and Absalão & Pimenta (2005) followed Warén (1992), who provisionally placed the genus Brookula in the trochid subfamily Eucyclinae; other authors placed the genus in the families Skeneidae (= "Cyclostrematidae" of authors, non P. Fischer, 1885) (e.g., Iredale 1912, Thiele 1925, Clarke 1961, 1962, Kay 1979, Hickman & McLean 1990, Dell 1990, Numanami & Okutani 1991, Numanami 1996, Tsuchida & Hori 1996, Lindner 1999 Barros et al 2001, Zelaya 2005 or in the family Liotiidae (e.g., Finlay 1924, Powell 1937, 1951, 1960; but see Powell 1979). To highlight the unresolved systematic status of the genus Zelaya et al (2006) placed the taxon under Trochoidea. Surprisingly, they transferred all so far known Antarctic Brookula species to Benthobrookula Iredale, 1912 only due to differences in protoconch diameter and ornamentation in both genera.…”

Among benthic mollusc samples from the deep Southern Atlantic Ocean collected during various expeditions of the German Research Vessel Polarstern were several representatives of the genus Brookula, of which four new deep water records are presented herein. Two of the species, B. bohni sp. nov. and B. charleenae sp. nov. are described and differences to congeners are given. For Brookula argentina (Zelaya, Absalão & Pimenta, 2006) and B. exquisita Clarke, 1961 range extensions are provided. The problematic use of the genus Benthobrookula instead of the genus Brookula is discussed and the use of the genus name Benthobrookula is discouraged until more detailed data on morphology and anatomy are available. For the first time the soft part gross morphology of Brookula pfefferi Powell, 1951 has been investigated and illustrated. Brookula decussata (Pelseneer, 1903) has to be regarded as a potential senior synonym of B. pfefferi. Examination of the type material has shown that B. antarctica Dell, 1990 does not differ from B. strebeli Powell, 1951 and the former becomes a junior synonym of B. strebeli. Morphometric data for all Brookula species from the Subantarctic and Antarctic waters of the Southern Atlantic Ocean are also provided, allowing a total of nine species to be included in this sector.
