Barnard, 1966; <i>H. gigas</i> (Birstein &amp; Vinogradov, 1955); <i>H. glutonis</i> Barnard &amp; Ingram, 1990; <i>H. trioculata</i> Chevreux, 1889; <i>H. wolfendeni</i> (Tattersall, 1909) all have this character. Among these species only <i>H. kapala</i>, <i>H. trioculata</i> and <i>H. wolfendeni</i> have a straight margin on the palm. <i>Hirondellea kapala</i> and <i>H. wolfendeni</i> both have the gnathopod 1 dactylus strongly overlapping the palm. Gnathopod 2 is subchelate in <i>H. kapala</i> but minutely chelate in <i>H. wolfendeni</i>. <b>Distribution.</b> South-eastern Australia in 720–1000 m depth.
