Rayons mous dorsaux (Total) : 7; Rayons mous anaux: 6. Distinguished from other Hemipsilichthys species by the exposed lateral process of cleithrum above pectoral fin insertion very reduced in size, never passing the origin of the pectoral fin spine; and by the arrangement of the hypertrophied odontodes on the lateral margin of head, which are longer posteriorly and slightly turned backwards (Ref. 42856).
