This common yellow species was named by Pruvot-Fol (1930) as a `n.sp. ou var.' from a pale yellow specimen from New Caledonia which she felt resembled the shape and size of the Mediterranean species A. leuckarti. It is most probable that the pale white specimen, tinged with yellow, from New Caledonia, that Risbec (1928) identified with A. leuckarti, is in fact a pale specimen of A. citrina. This speies is very common in eastern Australia and ranges in colour from pale, almost translucent, white, to a deep yellow depending on the colour of the sponge on which it is feeding.
