We report for the first time from Persian Gulf (Kish Island, Iran). Maximum length is 5 mm in Persian Gulf. We can observe H. cyanomarginata only 2-3 days in March in each year in Kish Island (Iranian Waters).

The shell is bubble-shaped, colored translucent whitish or yellowish, fragile, smooth, with no traces of ornamentation. The spawn is a translucent ribbon with whitish capsules laid in a one and half turn spiral laid flat on the substrate. There are toxic compounds with significant activity as feeding deterrents in H. cyanomarginata.
