Remark: Tanzanian populations are regarded as belonging to an undescribed species <i>C.</i> sp. "bifrenatus" by Ref. 95611. A revision of the conspecifity of the populations of <i>Chalinochromis popelini</i> on the eastern and western coast of Lake Tanganyika is necessary.
Comments: Rubble-dweller; sedentary; builds nest in the rubble; feeds on invertebrates growing on rocks which are hidden by the biocover (Ref. 6770).
