Diagnosis. Dactylogyridae . Body comprising cephalic region, trunk, peduncle and haptor. Tegument smooth. Head organs and two pairs of cephalic lobes present. Eyespots 4. Mouth ventral; pharynx muscular; intestinal caeca two, confluent posteriorly to testis. Common genital pore mid-ventral, at level of intestinal bifurcation. Gonads intercaecal, tandem; germarium anterior to testis. Vas deferens loops left intestinal caecum; seminal vesicle a simple dilation of vas deferens. Copulatory complex comprising male copulatory organ (MCO) and accessory piece. MCO sclerotized, clockwise; accessory piece articulated to base of MCO by delicate process. Seminal receptacle present, anterior to germarium; vaginal aperture dextral, sclerotized; vaginal duct a sclerotized tube. Vitelline follicles dense, overlapping caeca. Haptor armed with seven pairs of hooks with ancyrocephaline distribution ( Mizelle 1936), ventral and dorsal pairs of anchors, and ventral and dorsal bars. Hooks of each hook pair well-differentiated from the remaining pairs; shaft varying in robustness, proximal end of shaft of pairs 1–3, 6–7 with variably sclerotized expansions. Ventral and dorsal bars elongate, distinct. Anchors of distinct morphology and size; both with short deep, elongate superficial roots. Dorsal anchor with grooved shaft, bifid point. Parasites of the gill filaments of B. cupido ( Perciformes : Cichlidae ).
