- Citation:Helicosphaera intermedia Martini, 1965
Description: Like H. carterae but central-area spanned by curved disjunct bar (i.e. the bar behaves as a discrete crystal unit)
Remarks: Also similar to H. euphratis, but there are discrete opening above and below the ba, whereas in H. euphratis the bar virtually fills the central area.
Range: NP21 to NN12.
