Host specimens were sampled in the middle course of the River Sanaga (Cameroon) from January to October 2014. Two new species, Protoancylodiscoides auratum n. sp. from Chrysichthys auratus and Protoancylodiscoides combesi n. sp. from C. auratus, Chrysichthys nigrodigitatus and Chrysichthys longidorsalis, are herein described. These new helminths differ from the congeneric species by the size of the haptoral sclerites, the male copulatory organ length, the diameter and morphology of the vagina. At this stage, the present study suggests that Protoancylodiscoides auratum is oioxenous, while P. combesi is stenoxenous. The two new Protoancylodiscoides species bring to three the number of those parasitizing C. auratus, and to four the number of those described from Chrysichthys spp.

Cichlidogyrus djietoi n. sp. (Fig. 5) Type host. Tylochromis sudanensis Daget. Site. Gills. Type locality. Cross River at Mamf��, Cameroon (05�� 45 ' 58 " N; 9 �� 18 ' 38 " E). Other locality. Munaya River (Cross River tributary) at Akwen Bridge, Cameroon (05�� 45 ' 50 " N; 9 ��03' 39 " E). Specimens deposited. Holotype n�� 37768 and 2 paratypes n�� 37770 RMCA; 2 paratypes n�� HEL 511 MNHN. Etymology. The new species name is dedicated to Dr Djeto of the University of Yaound�� 1, Cameroon, for his technical advice during the manuscript elaboration. Description (based on 10 individuals). Adults 556 (367���658, 9) long. 163 (92���212, 10) wide at level of ovary. Pharynx globular 45 (27���62, 10) in diameter. Long dorsal anchor with guard four times longer than shaft, both thickened, sometimes presence of fenestra, blade regularly curved and not hollow: a = 59 (54���63, 16), b = 41 (36���45, 16), c = 5 (3���11, 16), d = 20 (16���25, 16), e = 11 (9���12, 16). Slightly arched and thick dorsal transverse bar, short auricles: x = 49 (44���58, 9), w = 9 (8���11, 9), y = 18 (14���21, 9), h = 10 (7���13, 17). Ventral anchor not similar to dorsal one, with very short guard and shaft, sometimes presence of numerous fenestra: a = 45 (39���48, 18), b = 42 (38���46, 18), c = 4 (2���5, 18), d = 9 (7���13, 18), e = 12 (10���13, 18). V���shaped ventral transverse bar: x = 55 (49���59, 18), w = 8 (7���10, 9). First marginal hook of medium size, third to seventh marginal hook short: Mh I = 22 (17���25, 18), Mh II = 13 (12���14, 17), Mh III = 22 (19���26, 14), Mh IV = 25 (23���28, 16), Mh V = 24 (22���26, 17), Mh VI = 23 (21���26, 18), Mh VII = 22 (18���25, 18). Tubular, thin and slightly spirally coiled penis (2 turns) starting in a bulb with developed heel: Pe = 41 (39���48, 10), He = 7 (6���9, 10). Accessory piece is a large gutter shaped band, ending in a narrow extremity which is folded back. We did not see a filament linking the AP and the penis: AP = 51 (43���56, 10). Short, arched and funnel shaped vagina: x = 10 (7 + 13, 10), w = 2 (2���3, 10). Remarks. This new species resembles its seven congeners already described from Tylochromis Regan 1920 host species (see above and C. chrysopiformis n. sp.) in having small auricles of the dorsal transverse bar (described as ���two small, hollow outgrowths on the anterior convex face��� by Pariselle & Euzet 1994), a spirally coiled penis and an accessory piece apparently not connected to the base of the penis (except for C. sigmocirrus n. sp. and C. chrysopiformis n. sp.). Cichlidogyrus djietoi n. sp. resembles C. kothiasi, C. muzumanii and C. chrysopiformis n. sp. in having marginal hook pair I more developed (22 ��m, 20.6 ��m, 24 ��m and 25 ��m, respectively), while C. sigmocirrus n. sp., C. pouyaudi, C. berrebii and C. mulimbwai have Mh I of small size (14 ��m, 12.3 ��m, 13.1 ��m and 15 ��m, respectively). By the shape of the penis and that of the accessory piece C. djietoi n. sp. is easily distinguishable from C. mulimbwai: developed (7 ��m) heel and thin short penis (41 ��m), large AP (51 ��m) vs. square heel (5 ��m) and long and thick penis (63 ��m), reduced (19 ��m) AP, respectively. Cichlidogyrus djietoi n. sp. resembles C. kothiasi by the shape of the penis and that of the accessory piece; their main differences are the dimension of sclerotized pieces, always larger in C. djietoi n. sp.: e.g. penis 41 ��m vs. 29 ��m, AP 51 ��m vs. 31 ��m, dorsal anchor length 59 ��m vs. 50 ��m, etc.; and the presence of a sclerotized vagina in C. djietoi n. sp. (vs. absence). Cichlidogyrus djietoi n. sp. resembles C. chrysopiformis n. sp. by the shape of the penis (except for that of the heel: cylindrical vs. flared) and of the accessory piece (extremities are of different shape: folded back vs. ending in three protuberances). The main differences are the dimension of sclerotized pieces of the haptor, always larger in C. djietoi n. sp. [e.g. dorsal anchor length 59 ��m vs. 50 ��m, ventral anchor length 45 ��m vs. 39 ��m, dorsal bar length 49 ��m vs. 41 ��m, etc.], and the shape of the vagina (funnel shaped in C. djietoi n. sp. vs. cylindrical in C. chrysopiformis n. sp.)., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2014, Four new species of Cichlidogyrus (Monogenea, Ancyrocephalidae) from Sarotherodon mvogoi and Tylochromis sudanensis (Teleostei, Cichlidae) in Cameroon, pp. 258-266 in Zootaxa 3881 (3) on page 263, DOI: 10.11646/zootaxa.3881.3.4, http://zenodo.org/record/229946, {"references":["Pariselle, A. & Euzet, L.

Ventral anchor similar to dorsal one but slightly smaller: a = 31 �� 0.8 (29���33, 39), b = 30 �� 0.7 (28���31, 39), c = 3 �� 0.7 (2���5, 39), d = 9 �� 0.7 (7���11, 39), e = 12 �� 0.9 (9���13, 39). Long, thin and V���shaped ventral transverse bar: x = 39 �� 1.7 (35���42, 40), w = 4 (3���5, 20). First and third to seventh marginal hook short: Mh I = 14 �� 0.5 (13���16, 39), Mh II = 12 �� 0.7 (10���13, 30), Mh III = 20 �� 1.1 (17���22, 34), Mh IV = 23 �� 0.9 (21���25, 35), Mh V = 24 �� 1 (21���26, 39), Mh VI = 22 �� 0.9 (20���25, 39), Mh VII = 21 �� 1 (18���23, 36). Tubular sinuous (slightly spirally coiled) penis starting in a bulb with reduced heel, accessory piece is a spirally coiled (1.5 turn) band wrapped round the penis and attached to the penis basal bulb by a very thin filament: Pe = 54 (49���60, 20), He = 2 (2���3, 20), AP = 44 (36���54, 20). No visible vagina. Remarks. This new species resembles its five congeners already described from species of Tylochromis Regan, 1920 [i.e. Cichlidogyrus berrebii Pariselle & Euzet, 1994; Cichlidogyrus kothiasi Pariselle & Euzet, 1994; Cichlidogyrus pouyaudi Pariselle & Euzet, 1994; Cichlidogyrus mulimbwai Muterezi Bukinga, Vanhove, Van Steenberge & Pariselle, 2012 and Cichlidogyrus muzumanii Muterezi Bukinga, Vanhove, Van Steenberge & Pariselle, 2012]; in having small auricles of the dorsal transverse bar (described as ���two small, hollow outgrowths on the anterior convex face��� by Pariselle & Euzet 1994). Its penis is not clearly spirally coiled and its accessory piece seems to be linked to the basal bulb of the penis by a thin filament, these features have not been mentioned for the other species harboured by Tylochromis spp., but they are hardly discernible. Cichlidogyrus sigmocirrus n. sp. resembles C. pouyaudi, C. berrebii, C. mulimbwai in having marginal hook I of small size (14 ��m, 12.3 ��m, 13.1 ��m and 15 ��m, respectively), while C. kothiasi and C. muzumanii have a more developed marginal hook pair I (20.6 ��m and 24 ��m, respectively). By the shape of the penis C. sigmocirrus n. sp. is easily distinguishable from C. mulimbwai: reduced heel (2 ��m) and 41 ��m long vs. developed heel (9 ��m) and 54 ��m, respectively. By the shape of the penis and that of the accessory piece (AP) C. sigmocirrus n. sp. is easily distinguishable from C. berrebii: reduced heel and AP a large ribbon vs. developed heel (massive) and AP a thinner ribbon, respectively, and from C. pouyaudi: reduced heel and smooth ending of AP vs. long heel and thickened AP with ending forming a beak, respectively., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2014, Four new species of Cichlidogyrus (Monogenea, Ancyrocephalidae) from Sarotherodon mvogoi and Tylochromis sudanensis (Teleostei, Cichlidae) in Cameroon, pp. 258-266 in Zootaxa 3881 (3) on page 261, DOI: 10.11646/zootaxa.3881.3.4, http://zenodo.org/record/229946, {"references":["Pariselle, A. & Euzet, L.

Etymology: N amed after Dr Andr�� Gilles (Marseille University) who studied fish genetics as part of the ANR program. Description (based on 8 individuals): adults 417 (347���463) (8) long. 94 (80���106) (8) large at level of penis. Pharynx globular 33 (28���37) (8) in diameter. Short dorsal anchor with guard two times longer than shaft and a regularly curved blade: a = 25 (24���27) (16), b = 20 (18���23) (16), c = 5 (4���6) (16), d = 10 (6���11) (16), e = 9 (8���11) (16). Regularly arched and long dorsal transverse bar, tapering toward the extremities: x = 39 (32���46) (8), w = 4 (3���5) (8), y = 14 (12���16) (8), h = 16 (13���19) (15). Ventral anchor same shape as dorsal, but slightly larger: a = 30 (29���31) (15), b = 26 (23���28) (16), c = 5 (4���7) (16), d = 12 (10���14) (15), e = 11 (10���12) (16). V���shaped and thin ventral transverse bar, branches straight: x = 35 (31���39) (16), w = 5 (4���6) (8). First uncinuli of small size, third to seventh long: U I = 15 (14���16) (14), U II = 12 (11���13) (13), U III = 34 (32���36) (13), U IV = 38 (36���40) (12), U V = 39 (37���40) (12), U VI = 35 (34���38) (14), U VII = 32 (31���33) (13). Male copulatory complex made up of a curved and strong penis, tapering towards its extremity, starting perpendicularly as a large ovoid bulb, a very large trapezoid heel, and a S-shaped accessory piece ending in a large hook with 7���8 tubercles and a triangular expansion on its convex face: Pe = 57 (54���62) (8), He = 13 (10���16) (8), AP = 39 (35���43) (8). Short, S���shaped vagina with thick and wrinkled wall: x = 17 (12���29) (7), w = 3 (2��� 3) (7). Remarks: Considering the morphology of the U 1 of small size, and U III to U VII long, of the MCC (penis with perpendicular and large proximal bulb, S-shaped accessory piece without associated auxiliary plate), and the presence of a sclerotised vagina, C. gillesi n. sp. resembles Cichlidogyrus anthemocolpos Dossou, 1982; Cichlidogyrus bonhommei Pariselle & Euzet, 1998; Cichlidogyrus bouvii Pariselle & Euzet, 1997; Cichlidogyrus dossoui Dou��llou, 1993; Cichlidogyrus douellouae Pariselle, Bilong Bilong & Euzet, 2003; Cichlidogyrus ergensi Dossou, 1982; Cichlidogyrus flexicolpos Pariselle & Euzet, 1995; Cichlidogyrus hemi Pariselle & Euzet, 1998; Cichlidogyrus kouassii N���Douba, Thys van den Audenaerde & Pariselle, 1997; Cichlidogyrus legendrei Pariselle & Euzet, 2003; Cichlidogyrus lemoallei Pariselle & Euzet, 2003; Cichlidogyrus ouedraogoi Pariselle & Euzet, 1996; Cichlidogyrus tiberianus and Cichlidogyrus vexus Pariselle & Euzet, 1995. The new species could be distinguished from all these others by the size and shape of the heel of the penis (large, trapezoid) and as well as that of the vagina (S-shaped, large and wrinkle walled)., Published as part of Pariselle, Antoine, Bitja Nyom, Arnold R. & Bilong Bilong, Charles F., 2013, Checklist of the ancyrocephalids (Monogenea) parasitizing Tilapia species in Cameroon, with the description of three new species in Zootaxa 3599 (1), DOI: 10.5281/zenodo.221201, {"references":["Dossou, C.

ETYMOLOGY. — Hamzati is given for Hamzat, name of the son of the first author of this article. FIG. 5. – Ligophorus hamzati n. sp.: morphological structures as in Fig. 1. Abbreviations: see Material & Methods. Scale bar: 30 µm. DESCRIPTION Flattened adult, 580 ± 33 (410-537) [30] long and 80 ± 10 (65-116) [30] wide at gonad level, pharynx: 26 (20-33) [28] larger diameter. Haptor well demarcated with 14 marginal hooks: 13 ± 0.9 (8-17) [360] long. Dorsal anchor with guard two time longer than shaft: a = 43 ± 4 (34-50) [60]; b = 34 ± 3 (28-39) [60]; c = 6 ± 0.7 (4-7) [60]; d = 13 ± 1.5 (9-16) [60]; e = 7 ± 0.8 (6-9) [60]. Dorsal bar V-shaped: 20 ± 2 (17-24) [30] long, 4 ± 0.7 (3-6) [30] wide and 7 ± 1.1 (5-10) [30] high. Ventral anchor: a = 42 ± 2 (36-45) [60]; b = 34 ± 2 (31-37) [60]; c = 7 ± 0.8 (5-10) [60]; d = 11 ± 1.3 (8-14) [60]; e = 7 ± 0.6 (6-9) [60]. Ventral bar, 39 ± 3 (32-47) [30] long and 9 ± 2 (6-13) [30] wide, with small antero-median protuberance and two lateral and symmetrical expansions: 10 ± 3 (4-18) [30] apart. MCO as copulatory tube: 92 ± 6 (81-100) [30] long, passes through a tubular accessory piece, 48 ± 7 (38-59) [30] long, with bifurcated distal extremity, each branches bifurcated also. Vagina: 51 ± 10 (21-67) [30] long. REMARKS This species is distinguished from all Ligophorus species by the shape of the accessory piece of the copulatory organ, which is bifurcated two times at its distal extremities. DISCUSSION The co-existence of fish hosts with a great difference in Ligophorus species richness is not exceptional. Euzet & Suriano (1977) observed only one species (Lig. angustus Euzet & Suriano, 1977) from Chelon labrosus (Risso, 1827) in the Mediterranean Sea, whereas the other mullet species may be parasitized by at least two species. Six species were reported from Liza carinata by Dmitrieva et al. (2012) and from Liza subviridis by Soo and Lim (2012), and at least 14 species were reported from M. cephalus by Dmitrieva et al. (2012). Similar differences in monogenean species richness were reported from cichlid hosts in West Africa by Pariselle et al. (2003). These authors drew a parallel between parasite species richness and host genetic diversity, which were both shaped by fluctuations of host populations through bottleneck or vicariant events. Therefore, in the case of Ligophorus from studied African mugilids, only the population of Liza bandialensis, which is endemic to a very limited area in Senegal, may have suffered numerous bottleneck events, leading to reductions in its size, and in turn to the loss of all its monogenean parasites. Among the three other widely distributed Liza species in Africa, Liza falcipinnis, which was infected by only one Ligophorus species, may have had a more stable history (and thus, a lower genetic and parasitic diversity) when compared to Liza grandisquamis, which was infected by three Ligophorus species and Liza dumerili, which according to Berrada Rkhami et al. (1993) was infected by over ten Ligophorus species., Published as part of Hafidi, Fouzia El, Diamanka, Arfang, Rkhami, Ouafae Berrada & Pariselle, Antoine, 2013, New species of Ligophorus (Monogenea, Ancyrocephalidae), parasite of Liza spp. (Teleostei, Mugilidae) off the Northwestern African coast, pp. 215-225 in Zoosystema 35 (2) on pages 222-224, DOI: 10.5252/z2013n2a6, http://zenodo.org/record/5160448, {"references":["EUZET L. & SURIANO D.

International audience; A checklist of the 23 species of Ancyrocephalidae (Monogenea) parasitizing Tilapia species sampled from both sides of the Cameroon Volcanic Line is provided. As already reported elsewhere, Cichlidogyrus aegypticus in Cameroon shows two different shape of its vagina, and C. tilapiae, C. arthracanthus and C. tiberianus were found on a wide range of host species. Among the 23 studied species of Monogenea, three are considered new species and are described herein: Cichlidogyrus berminensis n. sp. from Tilapia bemini, characterized by a short penis with marked narrow heel, a simple and straight accessory piece ending in a large hook, and a medium sized pair of uncinuli I; Cichlidogyrus gillesi n. sp. from Tilapia guineensis, characterized by a large and trapezoid heel of the penis and a S-shaped and wrinkle walled vagina; and Scutogyrus vanhovei n. sp. from Tilapia mariae, characterized by the presence of a distinct swollen portion of the penis. From a parasite's point of view, the CVL has no influence on species dispersion/distribution.

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., Published as part of Pariselle, Antoine & Euzet, Louis, 2009, Systematic revision of dactylogyridean parasites (Monogenea) from cichlid fishes in Africa, the Levant and Madagascar, pp. 849-898 in Zoosystema 31 (4) on page 851, DOI: 10.5252/z2009n4a6, http://zenodo.org/record/4520413, {"references":["PAPERNA I. 1963. - Enterogyrus cichlidarum n. gen. n. sp., a monogenetic Trematode parasitic in the intestine of Fish.

Of C. brevicirrus: Haplochromis longirostris (Hilgendorf, 1888), Haplochromis obesus (Boulenger, 1906), Haplochromis obliquidens (Hilgendorf, 1888), Haplochromis sp., Hoplotilapia retrodens (Hilgendorf, 1888) and Tilapia zillii (Gervais, 1848). SITE. — Gills. ADDITIONAL LOCALITIES. — Afram sector, Volta Lake and Adutor lower reaches of the Volta River, Ghana on H.fasciatus; Ghana on Chromidotilapia guentheri (Paperna 1979). REMARKS Paperna (1968) used for this species two spellings: C. dioncus and C. dionchus, as the first one was latter use by Paperna (1979) and other authors, we accept this spelling. Dossou & Birgi (1984) indicated that a proportion of individuals named C. dionchus by Paperna (1968: fig.6, p. 91) correspond to C. falcifer (individuals from Hemichromis fasciatus) and we agree with that. Dossou (1982) indicated that C. dionchus (on Sarotherodon galilaeus) is a valid species. Some hosts were added by Paperna (1979): Pseudocrenilabrus multicolor (Schoeller, 1903), Tilapia rendalli (Boulenger, 1897) and Haplochromis wingatii (Boulenger, 1902), but probably because of the presence of C. cf. brevicirrus, which was synonymised by this author with C. dionchus, when we propose to synonymise C. cf. brevicirrus with C. digitatus. In the same way, Paperna (1979) deposits a paratype (MRAC M.T. 35.586, probably C. cf. brevicirrus) from Tilapia discolor (Günther, 1903) for C. dionchus, we consider this specimen as being a C. digitatus. In the original description by Paperna(1968) the only true C.dionchus was illustrated by the drawing 5 (pl. 1, p. 91) and by the figures of C. brevicirrus in its original description (Paperna & Thurston 1969: 18), this latter species had been synonymised with C. dionchus by Paperna (1979); we agree with this conclusion., Published as part of Pariselle, Antoine & Euzet, Louis, 2009, Systematic revision of dactylogyridean parasites (Monogenea) from cichlid fishes in Africa, the Levant and Madagascar, pp. 849-898 in Zoosystema 31 (4) on page 862, DOI: 10.5252/z2009n4a6, http://zenodo.org/record/4520413, {"references":["PAPERNA I. 1968. - Monogenetic Trematodes collected from fresh water fish in Ghana.

Guinea and Sierra Leone on Sarotherodon occidentalis (Pariselle & Euzet 1997). Of C. halli typicus: lakes Georges, Albert and Edward, Kajansi fish ponds, Uganda on O. niloticus; Lake Albert, Uganda and Volta Lake and lower Volta River, Ghana on S. galilaeus; lakes Georges and Albert; Uganda on O. leucostictus; Kajansi fish ponds, Uganda on introduced O. niloticus vulcani and O. spilurus spilurus. REMARKS Price & Kirk (1967) synonymised Cichlidogyrus with Cleidodiscus Mueller,1934;this was confirmed by Price (1967). Price et al. (1969) rehabilitated Cichlidogyrus with five species (C. arthracanthus, C. bifurcatus, C. bychowskii, C. longicirrus and C. tiberianus), but kept in Cleidodiscus (valid genus) two species (C. halli and C. tilapiae). Paperna (1979) move back to Cichlidogyrus the two Cleidodiscus species found on African cichlid fishes (C. halli and C. tilapiae); this was confirmed by Douëllou (1993). Considering measurements and figures by Paperna (1979:11, pl.2 figs 2, 3) and after the examination of type material, we did not find significant differences between C. halli victorianus and C. halli. So, despite the opinion of Douëllou (1993), we consider that C.h. victorianus had to be synonymised with C. halli. The determination by Ergens (1981) of Tilapia zillii (Gervais, 1848) as host for C. halli in Egypt remains for us doubtful, in fact, this species is only found on mouthbreeders Cichlidae (i.e. genera Oreochromis and Sarotherodon)., Published as part of Pariselle, Antoine & Euzet, Louis, 2009, Systematic revision of dactylogyridean parasites (Monogenea) from cichlid fishes in Africa, the Levant and Madagascar, pp. 849-898 in Zoosystema 31 (4) on page 865, DOI: 10.5252/z2009n4a6, http://zenodo.org/record/4520413, {"references":["PRICE C.

REMARKS Ergens (1981) in Egypt found and re-described C. tiberianus on Tilapia zillii; he indicated that C. tiberianus on Oreochromis niloticus and Haplochromis longirostris found in Uganda by Paperna & Thurston (1969) (with some differences with original descriptions from Ghana or Israel) had to be considered as C. thurstonae. Dossou (1982) in Benin found C. tiberianus on Tilapia zillii, he agreed with Ergens (1981) about the confusion made by Paperna & Th urston (1969) between C. tiberianus and C. thurstonae. Douëllou (1993), according to Ergens (1981), considered that Paperna & Thurston (1969) confused C. tiberianus with C. thurstonae; she added that Paperna (1968, 1969 and 1979) may have made the same error. Pariselle & Euzet (1995c, 1996) found C. tiberianus only from hosts of the sub-genus Coptodon (namely: Tilapia coffea, T.dageti, T.guineensis, T.walteri and T. zillii).All these remarks are leading us to the same conclusion: all individuals described as C. tiberianus from mouthbreeders hosts (genus Oreochromis and Sarotherodon) have been confused with C. thurstonae by Paperna & Thurston (1969) or Paperna (1968, 1969 and 1979)., Published as part of Pariselle, Antoine & Euzet, Louis, 2009, Systematic revision of dactylogyridean parasites (Monogenea) from cichlid fishes in Africa, the Levant and Madagascar, pp. 849-898 in Zoosystema 31 (4) on page 872, DOI: 10.5252/z2009n4a6, http://zenodo.org/record/4520413, {"references":["PAPERNA I. 1960. - Studies on MonogeneticTrematodes in Israel. 2 Monogenetic Trematodes of Cichlids.
