From editor or global species database
Taxonomy Benham (1921) notes the similarity to the previously described E. heterosetosa, and takes trouble to note two differences between the two, but his comparison is with Ehlers' (1897) heterosetosa record from Magellan area rather than with McIntosh's original description (Marion Island).
Barroso et al (2017: 403) record and describe specimens attributed to the species from offshore Brazilian waters (20-23 S) in the Atlantic. Also, AM W27057 specimens, part of the Australian specimens which San Martin (2005) identified as E. heterosetosa, are re-identified by Barroso et al as E. anomalochaeta. This may indicate the two species are still confusable, even by experts. [details]
Type locality Benham (1921: 25) gives the location as from both Commonwealth Bay, Antarctica (67 S), which he lists first, and also subantarctic Macquarie Island (about 54.5 S). There is no indication otherwise that one site was more significant than the other for material. There is no information on the location at Macquarie other than it was intertidal. At Commonwealth Bay collection was Station A at from 4 to 7.5 m, 67 S, 142.6 E. [details]
Type material Uncertain. The Australian Museum lists only 17 specimens from Macquarie Island (collected by Hamilton) as syntypes. There is apparently no record there of the Commonwealth Bay Antarctic material collected by McClean. The Macquarie specimens are registered as W.617 Macquarie Island, -54.6167° 158.85° (54° 37' S , 158° 51' E). This location is inland, and seemingly a generic location for the island itself (mapping precision stated as 10km-100km). These geocoordinates must be disregarded as an accurate location, and the true shore location was probably never recorded. [details]
