Checked: verified by a taxonomic editorDistribution Antarctic Ocean. [details]

Checked: verified by a taxonomic editorEtymology The specific epithet heterosetosa derives from the Ancient Greek word 'heteros', meaning 'different', and the Latin adjective setosa, meaning 'hairy' or 'bristly', and refers to the different types of chaetae present in the species.  [details]

Checked: verified by a taxonomic editorHabitat Volcanic sand, "found amongst the bristles of Lagisca antarctica during the examination of that form".  [details]

Checked: verified by a taxonomic editorTaxonomy Taxonomy possibly uncertain as based on a now lost and possibly originally damaged type from off Marion Island, but later reported from distant locations by several authors. Also there is confusion with E. anomalochaeta Benham, 1921, and with a name misspelling as 'heterochaeta' perpetuated over several publications by Augener (1913, 1923, 1924). San Martin (2005) described only Australian specimens and did not compare accounts from elsewhere. Barroso et al (2017: 406) reports that "Based on specimens from the Kerguelen Islands, Monro (1939) synonymized [E. anomalochaeta] with E. heterosetosa McIntosh, 1885. However, based on the illustrations provided (Monro 1939: Fig. 9), all the [Kerguelen] material examined by Monro belongs to E. anomalochaeta and not to E. heterosetosa, which is a fairly different species (see San Martín 2005). [According to Barroso et al 2017] Exogone heterosetosa differs from E. anomalochaeta by having the median antenna longer than the combined length of prostomium and palps, by having falcigers with proportionally larger blades, and also by having spiniger-like compound chaetae, which are absent in E. anomalochaeta" [details]

Checked: verified by a taxonomic editorType locality Antarctic Ocean, off Marion Island (46º48'S, 37º49'30"E).  [details]

Checked: verified by a taxonomic editorType specimen The holotype is lost fide Monro (1939: 116 "Unfortunately McIntosh's type specimen is no longer in existence."). The type specimen is not recorded at the Natural History Museum data portal, where only specimens from B.A.N.Z.A.R. Expedition 1929-1931 are listed (these were recorded by Monro 1939 and (fide Barroso et al. 2017) are possibly E. anomalochaeta, not heterosetosa).  [details]
