Notes 
From editor or global species database
Checked: verified by a taxonomic editorDiagnosis Atelecrinus with centrodorsal usually tapering from the base; fulcral tubercles moderately to strongly developed; basals inflated interradially, forming continuations of usually well-developed ridges on centrodorsal; angle of radial profiles usually >90º; Iax2 hexagonal with weakly- to well-developed lateral knob- or ear-like lobes, or short diverging lateral margins; exterior margin of IIbr1 and IIbr2 and usually interior margin of IIbr3+4 flattened, often with a thick ridge along the edge. [details]

Checked: verified by a taxonomic editorDistribution N and W of the British Isles, Gulf of Mexico, S Blake Plateau, Strait of Florida, Bahamas, E Caribbean Sea and Brazil. Bathymetric range: 640–1450 (possibly 1454) m, with one Bahamian record from 2793–2825 m. A. helgae appears to occur in deeper water than A. balanoides wherever the two co-occur (maximum possible ranges given): 1061–1400 vs. 512–781 m in the Gulf of Mexico; 1003–1454 vs. 514–733 m in the Strait of Florida; 1450–2825 vs. 658–714 m in the Bahamas, and 866–1257 vs. 598–838 m in the Lesser Antilles. (USNM E17842 was collected somewhere between 733–1281 m off Tobago.) A. helgae also generally occurs at shallower depths at higher latitudes. Records from the Blake Plateau (805–897 m), NE Atlantic (698–900 m) and Brazil (640–763 m) are shallower than those for the Gulf of Mexico, Bahamas and Caribbean Sea (chiefly 1003–1454 m with one record off Barbados in 866 m), though this must also reflect varying oceanographic conditions: the Gulf of Mexico records are deeper than those from the Blake Plateau at similar latitudes. [details]
