Malakosaria cecilioi n. sp. (FIg. 16; TAbLE 18) Etymology. NAMED AFTER CECILIO FERNáNDEZ, IN APPRECIATION OF HIS FRIENDSHIP, SUPPORT AND CONTINUOUS ENCOURAgEMENT TO THE FIRST AUTHOR THROUgHOUT HER RESEARCH CAREER. Material examined. HΟlΟtype: CRBA-58239, STN PAT0210DR11, COLONY C. 30 MM LONg, 0.5 MM WIDE, WITH PROXIMAL AND DISTAL PORTIONS, SOME bRANCHES bROKEN. Paratypes: CRBA-58240, STN PAT0209DR14, COLONY C. 30 MM LONg, 0.5 MM WIDE, WITH PROXIMAL AND DISTAL PORTIONS; CRBA-58241, STN PAT1108DR10, COLONY C. 20 MM LONg, 0.5 MM WIDE, WITH PROXIMAL AND DISTAL PORTIONS; ATTACHED TO CORAL. Description. COLONY ERECT, DICHOTOMOUSLY bRANCHINg; COLONY C. 30 MM LONg bY 0.5 MM WIDE. ZOOIDS ELONgATE, ARRANgED bACK TO bACK IN OVERLAPPINg ALTERNATINg PAIRS. FRONTAL-SHIELD CALCIFICATION SMOOTH, IMPERFORATE, EXCEPT FOR A CRESCENTIC ASCOPORE AND SIX SHALLOW, SUbRECTANgULAR TO OVAL EXCAVATIONS AROUND THE SEMICIRCULAR ORIFICE, OF WHICH TWO OCCUR bETWEEN THE ASCOPORE AND THE ORIFICE; bETWEEN EACH PAIR OF PORE-CHAMbERS A MUCH SMALLER CIRCULAR PORE. NO ORAL SPINES, bUT A bLUNT TUbERCLE OCCURS ON EACH DISTOLATERAL CORNER OF THE ORIFICE. OVICELLS NOT PRESENT IN THE AVAILAbLE MATERIAL. Remarks. M. phΟlaramphΟs GOLDSTEIN, 1882 WAS ESTAbLISHED FOR A SPECIMEN COLLECTED FROM MARION ISLAND, SOUTH INDIAN OCEAN, bY THE CHALLENgER EXPEDITION. BUSK (1884) SYNONYMIZED M. phΟlaramphΟs, AND FURTHER MATERIAL COLLECTED FROM HEARD ISLAND, WITH OnchΟpΟra sinclairii BUSK, 1857, DESCRIbED FROM NEW ZEALAND. WHEN REDESCRIbINg THIS LATTER SPECIES, AS Calwellia sinclairii, GORDON (1984) ACCEPTED BUSK’S SYNONYMY CONCERNINg M. phΟlaramphΟs, bUT LATER SHOWED THAT MalakΟsaria IS SEPARAbLE FROM Calwellia (GORDON 1989). IT IS NOW CLEAR THAT M. phΟlaramphΟs IS NOT SYNONYMOUS WITH M. sinclairii FROM NEW ZEALAND bUT IS SYNONYMOUS WITH BUSK’S MATERIAL FROM HEARD ISLAND MISATTRIbUTED TO M. sinclairii. M. phΟlaramphΟs DIFFERS, INTER ALIA, IN HAVINg A PAIR OF SHORT, bLUNT TUbERCLES AT THE DISTOLATERAL CORNERS OF THE ORIFICE AND THESE ARE LACKINg IN M. sinclairii. ...
