Distribution map of Candacia worthingtoni by geographical zones
China Seas (East China Sea), Pacif. (W equatorial), Australia (Great Barrier), New Calédonia, SE Fidji Is., New Zealand (NW North Island), Kermadec Is.
N: 4 (Pacif. W: 4)
(348) F: 1,78-1,5; M: 1,84-1,7; (909) F: 1,73-2,4; M: 1,78-1,9; {F: 1,50-2,40; M: 1,70-1,90}

The mean female size is 1.853 mm (n = 4; SD = 0.3848), and the mean male size is 1.805 mm (n = 4; SD = 0.0854). The size ratio (male : female) is about 0.97
Rem.: depth ?; epipelagic.
Similar to C. bispinosa but may be distinguished (cf;inBradford-Grieve, 1999, p.178).
