Remarks

bathypelagic.
According to Roe (1975, p.325) as with Scolecithricella laminata (Farran, 1926) it is impossible to place the present species into any of the Scolecithricid genera defined by Bradford (1973), or into any of the remaining genera in this family. Both have some affinity to Lophothrix but also show a general resemblance to Amallothrix.
