It is distinguished from Conochitina dolosa Laufeld by a much smaller size and a specific foveolate
5-2 times as numerous as peripheral projections; interval between peripheral cord/keel and abapical suture progressively deeper and more channelled with growth; development of remaining spirals between adapical suture and periphery variable, sometimes distinct, sometimes obsolete; axial sculpture becoming less obvious with growth; apical whorls (not first) somewhat cancellate, becoming more foveolate
with elongate D-shaped pits on later whorls; pliculae in supra-sutural sulcus usually stronger and less close-set than those above peripheral keel.
Less obvious are the shape of the grains, which is dependent on the ratio of P/E, and the type of tectum discontinuities (perforate, microreticulate, foveolate
, or reticulate), which depend on the size of the discontinuities.
The diagnostic characters of Eremulus are (data summarized from descriptions of species): costulae well developed and visible; rostrum rounded; sensilli flagelliform, rarely spindle-shaped (exceptionally with small sensillar head); anterior part of notogaster with transverse foveolate
band; 10 to 11 pairs of notogastral setae; anal and adanal setae simple; epimeral setae branched (1c often setiform); genital and aggenital setae branched (exceptionally setiform).
slits; pollen monosulcate, proximal sculpturing psilate to foveolate
