A taxonomic review of the genus Acanella (Cnidaria: Octocorallia: Isididae) in the North Atlantic Ocean, with descriptions of two new species Author France, Scott C. text Zootaxa 2017 2017-09-22 4323 3 359 390 journal article 32016 10.11646/zootaxa.4323.3.2 e6ed2164-d69d-41e9-b0c1-814b1b6b967e 1175-5326 919804 282Cfa84-60F8-464A-Acc4-Bfcbbc69F6A9 Acanella robusta Thomson & Henderson, 1906 Figure 11 Acanella robusta Thomson & Henderson, 1906 : 33 ; Kükenthal, 1919 : 577 . Type : Bay of Bengal , Station 325, 18° 18’ N , 93° 25’ E . 843 fathoms depth. Deposited in the Indian Museum, Calcutta. For description see: Thomson & Henderson 1906 Remarks: We found two specimens with Haplotype H and their morphology corresponds to A. robusta ( Figure 11 ). They have prominently tuberculated sclerites, which give the sclerites a textured appearance that is visible to the naked eye, and small rods in the coenenchyme. A. robusta also differs from A. rigida by its large squat base ( 2 mm ) and large, obliquely arranged sclerites that do not reach the whole length of the polyp, as they do in A. rigida . A. robusta is found deeper than A. rigida (1019̄ 1390 m ; Figure 3 ). Distribution: Our collection has expanded the known locations of A. rigida from the Andaman Sea and Bay of Bengal off the coast of Myanmar ( Burma ) to the Bismark Sea off the coast of Papua New Guinea . The known depth range is expanded to 1019̄ 1542 m .
