Brucerolis gen. n., and Acutiserolis Brandt, 1988, deep-water southern genera of isopods (Crustacea, Isopoda, Serolidae)
Acutiserolis Brandt is rediagnosed (coxal dorsal plates 2–5 slot into each other with no aperture between; coxal plate 6 has a blunt process on its anterior margin slotting into a groove on coxa 5 and isolating an oval aperture; with prominent middorsal pereonal and pleonal spines; pleotelson with a...

| Summary: | Acutiserolis Brandt is rediagnosed (coxal dorsal plates 2–5 slot into each other with no aperture between; coxal plate 6 has a blunt process on its anterior margin slotting into a groove on coxa 5 and isolating an oval aperture; with prominent middorsal pereonal and pleonal spines; pleotelson with a sharp middorsal keel, upturned posteriorly; and sharply defined longitudinal sublateral keels ending acutely) and confined to the type species, Serolis spinosa Kussakin, 1967, and two species of Cuspidoserolis Brandt, 1988 syn. n. Brucerolis gen. n. , (type species Brucerolis nowra sp. n. ) is erected for species previously assigned to Acutiserolis but from which it differs inthe coxal dorsal plates 2–6 interacting only by means of key-like lobes, coxal plate 6 exceeding the pleotelson by at least the pleotelson length, middorsal spines being absent or obscure, and the pleotelson lacking ridges and keels. Four other species are included: Brucerolis bromleyana (Willemöes-Suhm, 1876); B. cidaris (Poore & Brandt, 1997); B. macdonnellae (Menzies, 1962); and possibly B. maryannae (Menzies, 1962). |
