Newmanellinae n. subfam. is proposed for five species of tetraclitid barnacles that are referred to two genera. The tropical western Atlantic Newmanella ROSS, 1969 contains N. radiata (Bruguiére), 1789, N. hentscheli (Kolosváry), 1942 and N. kolosvaryi n. sp. from the east coast of Panama. The western Pacific Yamaguchiella n. gen. contains two subgenera. The type species of Yamaguchiella s. s. is N. coerulescens (Spengler), 1790 and that of Rosella n. subgen. is N. vitiata (Darwin), 1854. Tetraclitella Hiro, 1939 contains two distinct groups, the nominotypical Tetraclitella s.s. and Eotetraclitella n. subgen., the type species of which is Tetraclitella darwini (Pilsbry), 1928. Tetraclitella digita Rosell, 1975 from the Philippines is a subjective synonym of T. karandei ROSS, 1971 from India and Taiwan. Tetraclita aoranga Foster, 1978 from New Zealand is assigned to Astroclita Ren and Liu from the South China Sea.

The bioassay experiment carried out on the avoidance of byssal thread attaching of two mussels Mytilus galloprovincialis and Perna viridis to hydroxides which was generated by anodic solution method on the surface of mild steel and pure zinc electrodes respectively. The results were obtained to reveal remarkable efficiency which could not help getting out of the attaching on both metal hydroxides because of being extremely soft and easily broken like a clay and sea bottom mud.
