Abstract
Heterodina Schotte & Kensley, 2005 is revised with Heterodina qeshmensis sp. nov., described from the subtidal zone of the Qeshm Island, southern Iran. Heterodina qeshmensis sp. nov. is characterized by: unornamented dorsal surfaces, wide and anteriorly concave epistome, and the appendix masculina with sub-parallel margins and not extending beyond the distal margin of the endopod. A key to the species is provided. The penial processes of Heterodina mccaini Schotte & Kensley, 2005 is also re-illustrated.
