Diagnosis
Genus of the family
Dzhulfitidae
with moderately large conch; maximum adult diameters are between 80 and
95 mm
. Subadult and adult stages with rectangular and compressed whorl profile. Subadult stage with weak to moderately strong lateral ribs; adult stage with weak ornament. Suture line with an external lobe that is much shorter than the adventive lobe.
Remarks
Stoyanowites
is separated from most of the other genera of the family
Dzhulfitidae
by the short external lobe, which does not reach the depth of the adventive and lateral lobes. Only
Dzhulfites
is similar in this respect, but this genus is characterised by coarse ventrolateral nodes absent in
Stoyanowites
.
