The adult medusa of Pteroclava krempfi is described for the first time. Morphology of both newly liberated medusa and hydroid is defined and compared to former descriptions. A distinctive character of the medusa is the presence of telotrichous macrobasic euryteles in exumbrellar pouches above the two perradial atentaculate tentacular bulbs, and the absence of exumbrellar pouches above the two perradial tentaculate tentacular bulbs. The hydroid of the nominal species Zancloidea philippina is reported for the first time since its initial description, confirming its referral to the genus Asyncoryne. The definition of the family Cladocorynidae is discussed and modified, with discussion of the superfamily Zancleoidea.
