Genus Enterogyrus Paperna, 1963 View in CoL

TYPE SPECIES. — Enterogyrus cichlidarum Paperna, 1963 , by original designation.

OTHER SPECIES INCLUDED. — Enterogyrus amieti Bilong Bilong, Euzet & Birgi, 1996 ; E. barombiensis Bilong Bilong, Birgi & Euzet, 1991 ; E. coronatus Pariselle, Lambert & Euzet, 1991 ; E. crassus Bilong Bilong, Birgi & Euzet, 1996 ; E. foratus Pariselle, Lambert & Euzet, 1991 ; E. malmbergi Bilong Bilong, 1988 ; E. melenensis Bilong Bilong, Birgi & Lambert, 1989 .

DIAGNOSIS. — Ancyrocephalidae . Pear-shaped body enlarged posteriorly; thick tegument transversely striated (except on haptor). Four ocellae, members of anterior pair wider apart and smaller than those of posterior, anterior with or without lenses.Pharynx muscular; short oesophagus followed by two lateral intestinal caeca without diverticula, joined posteriorly. Haptor cup-shaped, opening ventrally or in two parts: one bulbous and one peduncular shaped. Two unequal pairs of anchors. One ventral transverse bar, straight or V-shaped. Fourteen equal uncinuli, each with points orientated ventrally (haptor cup-shaped) or anteriorly (haptor bulbous and peduncular shaped).Testis at level of junction of intestinal caeca.Vas deferens encircling left intestinal caeca, widening to form a seminal vesicle, continuing as narrow duct to base of penis. Sub-median tubular and spirally coiled (clockwise) penis, enlarged at base; accessory piece absent. Ovary median pre-testicular, ovoid, sometimes U-shaped.Vagina not observed. Stomach parasite of Levantine and African cichlid fishes.

REMARKS

Two species are not considered in this study because they were described from the stomach of Etroplus suratensis (Block, 1790) in Asia. These species ( Enterogyrus globodiscus (Kulkarni, 1969) and E. papernai Gussev & Fernando, 1973 ) are characterised by having two transverse bars (vs. only one for African and Levantine species), according to Paperna (1979) we think that this difference will be sufficient to justify splitting Enterogyrus into two genera.
