Zevinaella, Shalaeva, Kate & Newman, William A., 2016

Genus Zevinaella gen. nov.

Type species. Scalpellum rodstromi Boone, 1927 .

Diagnosis. Arcoscalpellinae with 12 capitular plates (L2s absent). Umbones of T, S, C, L1, CLs apical. Associated with Crinoidea (Echinodermata).

Composition. Two species: Zevinaella rodstromi ( Boone, 1927) new combination and Zevinaella volentis sp. nov.

Remarks. The more or less closely related T. pentacrinarum ( Pilsbry, 1907) has not been included in the new genus because its L2s are obviously present, its peduncular plates stand in 6 rather than 8 tiers, and it occurs on Neocrinus rather than Stylometra . However, supplementary descriptions of the holotype and additional material of T. pentacrinarum are given below.

Distribution. Atlantic, Western-Central: Caribbean. Known depth range 60 to 510 m.

Habitat. Crinoid assemblages of outer reef slopes.

Etymology. Zevinaella is named in honor of the late Professor Galina Zevina ( 1926–2002) of Moscow State University ( Russia), author of more than a hundred papers and books on barnacles as well as an inspirational, warmhearted teacher and friend, whose untimely death in an automobile accident left a void in cirripedology (cf. Kolbasov et al., 2005).
