Halecium balei Fraser, 1911 : 46 [new replacement name for Halecium gracile Bale, 1888 , not Halecium gracile Verrill, 1874 ]. Syntypes . NMV F58760 : Australia , New South Wales , Port Stephens , on Aglaophenia sp., labelled as “co-types”; two microslides ( Stranks 1993: 6 ). Type locality. Australia : Port Stephens and Port Jackson ( Bale 1888 ). Current status. ? Invalid. Remarks. Halecium balei was proposed by Fraser (1911) as a replacement name for H. gracile Bale, 1888 , recognized as an invalid junior primary homonym of H. gracile Verrill, 1874 . In turn, H. balei has been held to be a junior subjective synonym of H. delicatulum Coughtrey, 1876 ( Vervoort & Watson 2003 ), although the status of the species is still open to question ( Galea et al . 2014 : 15). As an objective synonym of H. gracile Bale, 1888 , Halecium balei Fraser, 1911 has the same name-bearing type material (ICZN Art. 72.7), namely that at the NMV (NMV F58760 ). A search for type material of H. gracile in collections at the Australian Museum, Sydney, was unsuccessful (Stephen Keable, personal communication, 24 January 2017 ).
