A description and differential diagnosis of a new species, <i>Pachycordyle kubotai</i>, is presented. Hydroid colonies, hydranths, and gonophores of this species are described in detail. Peculiarities of medusoid development and oocyte maturation are analyzed. The genus <i>Pachycordyle</i> is rediagnosed and an identification key to species assigned to it is provided. <i>Clavopsella</i> is regarded as congeneric with <i>Pachycordyle</i>. <i>Thieliana</i> is established as a new genus for species subsequently and erroneously assigned to <i>Clavopsella</i>. The taxonomic status of species referable to Thieliana is discussed. Justification is provided for our position that these genera belong to the family Clavidae. Characteristics of genera assigned to the family Clavidae are summarized. Data on the geographic distribution and ecology of the species of <i>Cordylophora, Pachycordyle</i>, and <i>Thieliana</i>, referred here to the subfamily Cordylophorinae, are presented.}, number={S1}, journal={Scientia Marina}, author={Stepanjants, Sofia D. and Timoshkin, Oleg A. and Anokhin, Boris A. and Napara, Tatiana O.}, year={2000}, month={Dec.}, pages={225–236} }
