Abstract: | A new species of pelagic amphipod, Lestrigonus ducrayi sp. nov.,from eastern Australia, is described and illustrated. It isvery similar to Lestrigonus bengalensis Giles, 1887, but isreadily distinguished by a relatively shorter telson (aboutone-third peduncle uropod 3) and, in mature males, pereonites15 are fused as in females. The two species often occurtogether in the same plankton sample; the new species beingmore abundant inshore, although both species seem to preferinshore waters. A key to the species of Lestrigonus is provided. |
