Abstract
The new subfamily Lockhartiinae presents a peculiar umbilical structure characterized by umbilical cavities that are delimited by successive foliar walls and numerous parallel umbilical piles. The shells are always low-trochospiral, with an equatorial to axial diameter ratio always above 1. The dorsal side of the shell bears heavy ornaments from more or less thickened limbate spiral and cameral sutures to ribbed or cancellate ornaments. Four genera (Rotalispira n. gen., Lockhartia, Dictyoconoides, Sakesaria) and 19 species (R. scarsellai, R. pyrenaica n. sp., L. praehaimei, L. haimei, L. retiata, L. diversa, L. roeae, L. conditi, L. hunti, L. tipperi, D. flemingi, D. kohaticus, D. cooki, S. cotteri, S. costulata, S. cylindrata, S. pyrum, S. somalica, S. trichilata) are described and illustrated.
